The decision to not require seats is one of the best regulatory decisions I have ever heard of, and I wish this kind of thought process was more present in all kinds of places. The funny thing is that, I bet if it were used more broadly, given the absolutely enormous safety advantage that flying has over basically any other mode of transportation, there would be a non trivial number of other flight safety regulations that would get reconsidered.

5h agoHN ↗

Going back to pre-9/11 security screening would probably save lives. The extra time & hassle required to get through security (and the fact that only passengers can go through) means that some people drive instead of fly. Driving is less safe than flying, so some of those people die in car wrecks.

5h agoHN ↗

The extra time & hassle required to get through security (and the fact that only passengers can go through) means that some people drive instead of fly.

I suspect it leads to more people not travelling at all (or much shorter distances) and net saves lives in both the relatively immediate travel sense and even moreso in the broader analysis including net carbon emissions and their effect in climate change.

(It is still a mix of corrupt corporatism and authoritarian conditioning that should be ended for that reason.)

4h agoHN ↗

I'm not sure I disagree. I don't have numbers but, anecdotally, you sure hear a lot of "But flying is such a hassle" which is sorta true but not sure how much more than it's ever been especially if you're willing to pay a bit more. I'm not sure how many people translate that into "So I'll just drive 1,000 miles instead."

In Europe (and the US Northeast Corridor), I do favor trains to avoid going to and dealing with airports, but they're no panacea either. And I say this as someone with the various passes that make flying easier.

4h agoHN ↗

I can drive for 5 hours, or take the 1 hour flight. The one hour flight has a total time of over 5 hours when you include getting to the airport, clearing security and getting bags at the other end. Plus I will not have a vehicle. For one person the cost is probably a wash, for two or more driving will be cheaper. 1000 miles does tip towards flying. Under 300 miles driving is going to be way less hassle to drive.

3h agoHN ↗

It has very little to do with security though. I usually go through security in 5 minutes at my home airport. I do leave a lot more time than that partially because my car company sort of insists on it. (Of course, the car company is another cost.)

Honestly, it would be faster and possibly cheaper for me to drive to Manhattan than take the train--in which case security doesn't enter in at all. And certainly for two people. But I hate driving into Manhattan.

2h agoHN ↗

International trains have security too nowadays. In fact they're trying to feel an awful lot like planes...

It is what it is. Governments can't risk the bad publicity of a terrorist attack. A car accident doesn't even make the news.

4h agoHN ↗

While I don't disagree and I think a lot of it is just nonsense security theater, it is probably worth noting that incidents of airline terrorism have fallen completely off the map in this new regime.

Not sure how old you are but bombings and hijackings of airplanes were just kind of a common fact of life when I was a kid and I was there on 9/11 as well.

There's at least some element of Chesterton's fence that could come into play here.

4h agoHN ↗

Locking the cockpit doors and beaching the social contract that no one gets hurt in a hijacking stopped it, not TSA.

1h agoHN ↗

The trade-off here is that there's at least one instance where a protocol gap and a locked door led to intentional CFIT (Germanwings 9525)

1h agoHN ↗

The biggest difference to hijackings post 9/11 has nothing to do with pre-boarding security: Locking the cockpit door.

4h agoHN ↗

I would argue that high speed regional rail would address this as well. How many flights from regional airports to major hubs could be eliminated with a decent train?

4h agoHN ↗

If you're comparing HSR to air travel with post 9/11 security then there's a a moderate number. However, once you have HSR that moves a significant amount of people, you WILL get post 9/11 security there as well, taking the number to approximately zero.

1h agoHN ↗

Plenty of places operate much more dense transit without that level of security.

Trains, even HSR have essentially zero hijacking risk relative to airplanes, and proper safety interlocks make them very difficult to use the vehicle as a weapon.

At that point, your terrorism risk is approximately on level with any other dense transportation interconnect.

3h agoHN ↗

Regular rail is already this, and for much of the Northeast is already roughly at or near time parity with flying, all things considered. If you have to arrive at the airport 2 hours early, and it takes 30 minutes-1 hour to leave by whatever means (renting a car, waiting for a bus or Uber, etc. + baggage return and simply walking through the airport), and then another 30 minutes-hour to actually arrive at your destination, arriving at your local station 10 minutes before departure and arriving in the city center/local destination station starts to look really attractive for flights of <2 hours/train rides of <6 hours.

3h agoHN ↗

High speed rail is only cost-effective between major cities that are within a few hundred miles or so. Otherwise you don't have enough passengers to recoup the cost of building & maintaining the rail system.

For example: Spokane to Seattle is about 230 miles in a straight line, or 280 miles driving. A flight takes less than an hour (not even 40 minutes of which is spent in the air) and costs $80-130 one way. A train traveling 200mph nonstop would take 1 hour 24 minutes. Building high speed rail costs $20-$200 million per mile (the upper end of that is California HSR). If we optimistically assume $20m/mile, constructing the line will cost $5.6b. If all SEA-GEG passengers (677k per year) choose to take rail instead of flying, and we want the project to pay for itself after 50 years, then each ticket will need to cost $165. This also assumes no cost to maintain or operate the rail line.

2h agoHN ↗

You sent me down a rabbit hole, thank you, reading about the current state of Cascadia HSR, what it would take to make the current 79mph tracks capable of 110mph or 125mph (spoiler, 110mph is barely worthwhile and 125mph is an overt waste of effort), etc. The more I look at the numbers, the more I think the future does not look like HSR in the PNW. Wildly expensive, low ridership.

I wonder if we could not get most of the benefit by doing substantially cheaper options like separating freight from rail on major routes, electrifying parts of it where feasible. And maybe taking specific segments in areas where the track conditions are already favorable and increasing the maximum speeds on those segments. Probably two-thirds of the route between Portland and Salem, for example, is already suitable with modest upgrades to hit 125 mph. And basically all modern trains are capable of that speed already.

2h agoHN ↗

Do you have any evidence on this? As a personal anecdote, driving is as much a hassle if not more than flying, depending on the distance. I care more about cost first and time second. Even if you buffer in getting to the airport 2 hours early, flying is almost certainly the fastest (compared to driving and train, if available) unless you're flying from like, bos -> nyc. Security at airports hasnt felt like a hassle for me in years (at least the past six years).

I had two recent trips to the same destination. I drove once because it was so much cheaper (during the world cup when air fare was jacked up) compared to the train or flying. I flew the other time, because it was only a little more expensive and flying is faster and less of a hassle, actually.

Additionally, given the article talks about families, the cost comes down a lot with multiple people in one car vs multiple plane tickets. If we want to make travel safer by putting fewer cars on the road, make alternatives cheaper. They're already more convenient to me...

3h agoHN ↗

The FAA has one of my favorite examples of thoughtful rulemaking. They haven't banned flying with a baby on your lap, because the extra cost would mean many parents would drive instead.

Is this really why the rule was made? Did they really have safety of driving in mind or is this just in the interest of the profits of airlines?

It seems like if they really had safety in mind there are better solutions:

* Subsidize the 2nd seat for parents with children from tax dollars

* Criminalize many intentional driving violations

* Build high speed rail

1h agoHN ↗

Is this really why the rule was made? Did they really have safety of driving in mind or is this just in the interest of the profits of airlines?

Yes. There are multiple public documents showing this, ex:

The FAA has determined it is not appropriate to mandate the use of CRSs in aircraft now. We remain concerned that if we require children under 2 years old to be in an approved restraint system (which requires a passenger seat), affected operators might find it necessary to charge a fare for transporting these children. (Currently most, if not all, operators do not charge a fare for children under 2 years old who are held in an adult's lap.) In turn, for economic reasons some adults might decide to drive in automobiles to their destinations rather than fly. The FAA is concerned because automobile injury and fatality rates are higher than aircraft injury and fatality rates. As a result, there would be a net increase in transportation injuries and fatalities as families opt, for economic reasons, to drive rather than fly to their destinations.

https://www.federalregister.gov/documents/2005/08/26/05-1678...

* Subsidize the 2nd seat for parents with children from tax dollars

That's not something the FAA or DOT can do.

* Criminalize many intentional driving violations

That's not something the FAA or DOT can do.

* Build high speed rail

That's not something the FAA or DOT (unilaterally) can do.

3h agoHN ↗

What happens when you factor in the downstream effects of carbon emissions (based on whatever the best projects are right now)?

5h agoHN ↗

Sort of tangential to the rulemaking discussion but I’ve had two flight attendants note that unbuckling the carrier during takeoff and landing is required due to the risk of breaking the child’s back.

If the adult is pitched forward with the child strapped to their chest (facing inward) then they risk bending the child’s spine backwards.

5h agoHN ↗

The rules don't say that you have to hold your baby facing forward, and front-facing baby carriers are also banned during takeoff & landing.

5h agoHN ↗

"All things considered" is easily attacked by vultures and businesses typically pick it apart.

PFAS bans are another where the whole class is likely hazardous but EPA will continue chasing specific molecules rather than consider the whole class.

Now adays, chem engineering will just put different monomers in and move on untill 20 years and we find, all things considered, it still reaches humans at toxic levels.

5h agoHN ↗

There is a deeper issue, in a crash, a poorly secured rigid baby carrier seat becomes a potentially lethal projectile. Worst comes to worst, today, the projectile is an infant. An infant is substantially softer and less massive than a rigid seat containing an infant.

For soft babywearing carriers, the outlook is also grim. The kinematics of the baby, adult, carrier and airplane seat lead to crush injuries that are worse than the poorly restrained arm hold version.

Could there be a solution here that straps around a seat to give babies a safe seat?

Yes, but it wouldn't necessarily be easy to use or consumer friendly. The ideal solution would have the baby with their back facing front, and the attached carrier facing inwards towards the seat. It would have to be carefully specced and tested so no unverified, third-party seats... Logically extrapolated, in this scenario, the airline becomes responsible for the baby's wellbeing. And I don't think that's a good place for the airlines to be?

5h agoHN ↗

Is a rigid carrier more dangerous as a projectile, or more so as an obstacle to evacuation?

5h agoHN ↗

Lethal projectile. 2x more mass = 2x more energy.

In this scenario, there isn't going to be evacuation. At best, it's search and rescue. At worst, search and recovery.

The poorly attached rigid seat, with a well-secured infant, increases the infant's odds of survival, but the mass increase reduces everyone else's odds of survival (including other infants and caregivers).

There are designs and policies where it becomes "worth it." But it would have to be study to figure out at what point the tradeoff becomes worth it.

It's a grim outcome, but great safety engineering is built on the worst case taken seriously.

4h agoHN ↗

I've only done one return flight with Thai Airways (LHR-BKK) with a child seat, but it's only allowed by a window seat or in the middle seat in a 3x3x3 configuration. Probably standard but I didn't check for a while.

(Sorry, meant to reply to parent)

1h agoHN ↗

Pretty much the same experience I've had on other carriers. Where you can/can't put them is pretty logical.

4h agoHN ↗

In this scenario, there isn't going to be evacuation. At best, it's search and rescue. At worst, search and recovery.

Scenarios without evacuations are ones where nearly everyone or everyone is already dead. That’s not a case to optimize for.

5h agoHN ↗

Not sure how much we need to optimize for this. Plane crashes are rare. I'm happy to risk a baby seat crashing into me if my plane crashes if it means the 99.99987% of the flights are slightly better.

5h agoHN ↗

Turbulence that loosens objects is very common.

My guy a car seat will do nothing in a crash.

3h agoHN ↗

Yeah we're flying in aluminum cans with hundreds of pounds of luggage above our heads held in by doors with doors that regularly malfunction. The occasional baby seat that might become a projectile seems low on the list of things likely to impact me, much less change the outcome appreciably in a crash.

2h agoHN ↗

Plus, everyone's poorly secured laptops and phones flying around.

1h agoHN ↗

In this context the baby that isn't strapped in is the loose object. The use of car seats and harnesses is not just about a full loss of control of the aircraft and resulting crash.

1h agoHN ↗

This isn't about car seats, it's about baby carriers, and it's not about protecting you in a car crash:

When our babies were little, carriers were massively helpful in flying. The baby likes it, and your arms are free.

The carrier means the baby can sleep wherever we are, and I can have my hands free. If you can breastfeed in the carrier, even better because the baby can eat as you’re navigating the airport, etc. Carrying the baby centered on your body is easier on your back than carrying them in the carseat. Plus it’s good for walking / sightseeing at your destination.

5h agoHN ↗

The math is more that benefits aren't that great and the dangers are pretty big, especially if someone fails to properly secure the carrier and you get a rejected takeoff

4h agoHN ↗

Really? Flight staff are checking to make sure everyone wears a seatbelt. Check the carriers, too. Seems like a non-issue.

What parent in their right mind is bothering to bring a baby carrier and can’t manage to secure it?

4h agoHN ↗

attaching a baby carrier / car seat to a vehicle seems easy, but a recent study showed that about half of US drivers had their seats installed incorrectly, and these are vehicles where the driver has unlimited time and resources to get it right.

I can't imagine that percentage goes up when strapped for time and under pressure during aircraft boarding.

https://www.nhtsa.gov/press-releases/national-car-seat-check...

4h agoHN ↗

Vehicles are also more dangerous which should tell you something about the actual impact on safety.

50m agoHN ↗

What's most important is what's inside the vehicle. People outside it are usually lower class and therefore not worthy of serious consideration.

Driving small humans around in anything less than a hummvee is neglect. /s

4h agoHN ↗

Importantly, though, a crewmember doesn't stop by to check if you strapped the car sear correctly

2h agoHN ↗

In my experience they always stopped by to check that the seat was certified and that you knew how to install it. For aircraft install though it's usually simpler than a car because the only way to do it is a belt pass through.

4h agoHN ↗

I remember the very first time I installed a car seat, I rigorously followed the instructions, verifying each step both textually and by image. After that, we had it inspected by the local FD who said "you did it wrong" and rearranged it in a way that looked wrong to me (some detail with the straps and routing). I still don't know who did it right.

4h agoHN ↗

Same experience. My wife and spent more than an hour trying to get it all right, then went to the inspection facility, and they completely re-did it all. I now have teenagers, but still don't actually know how to install a seat correctly.

56m agoHN ↗

Maybe car seats have gotten easier but with my two young kids I've had to install and uninstall car seats dozens of times. 5 out 6 different car seats. It only takes like 2 minutes to do it right.

1h agoHN ↗

The installation mode for planes is actually easier due to the standardization of the actual seat belts versus for cars the carriers will have different instructions depending on whether UAS is present, belt install, top tether, etc. In an aircraft there's really only one way to do it which is passing the belt through.

4h agoHN ↗

Usually what I see happen is that people will wait until they are done checking seatbelts and then take them off.

What parent in their right mind

As a parent, you would be extremely saddened to learn that many are not.

2h agoHN ↗

My experience has been that as long as your car seat has the right certification they are allowed and the flight staff do check both that it has the certification sticker and that you've installed then correctly. The installation mode for planes is typically significantly simpler than in a car because it's just the belt pass through and seat angle. There's nowhere to attach a top tether.

4h agoHN ↗

I do (barely) buy this for car seats. It obviously makes no sense for the baby carriers that the article is talking about.

2h agoHN ↗

Indeed. This is the same type of bankrupt government logic that classifies a slingshot as a firearm.

2h agoHN ↗

Also, car seats are actually allowed as long as they have the right certification sticker.

1h agoHN ↗

Nobody is going to survive a crash where a 3 lb soft wearable baby carrier is travelling at a high enough relative speed to do any damage.

1h agoHN ↗

Not a crash. A badly-secured heavy object will injure someone in turbulence where otherwise no injury would have occurred.

11m agoHN ↗

Soft wearable baby carriers are not heavy.

5h agoHN ↗

I'll bet that is less of an issue than the issue of evacuation.

Currently, aircraft seatbelts are designed for very quick release when needed with no training or muscle memory needed, shove your hand at your waist and pull the metal flap and it immediately comes apart. This seems like it could be an issue with baby carriers, since a) you can probably expect a bit more complex arrangement of straps buckles and b) lack of muscle memory or training on presumably a different style of carrier than what you ever ever use outside an airplane.

A second issue that comes to mind, how to do seating arrangements? Imagine a parent struggling to remove baby during a emergency. Imagine a 3 seat row window side, where others are stuck waiting for parent to release baby.

This seems like a certification nightmare

4h agoHN ↗

You are only allowed to have the carrier in the window seat from the flights I’ve been on.

1h agoHN ↗

Certified rigid car seats are already allowed onboard and pretty much every airline you've ever flown on has clear guidelines on which seats they can be placed in for exactly that reason.

4h agoHN ↗

I think the challenge here might be that, as the article says, this is all just hypothetical and hasn't been empirically tested. It also sounds like a lot of the reasoning predates modern babywearing equipment quite a bit.

With our kids, we used two different devices. One was just a long strip of cloth that you tie in a special way. The other was a more structured carrier with straps and buckles and all that good stuff. For both of them, the child faces toward the parent, so they would be rear-facing relative to the plane. And both have an option to fully support the head. The main purpose there is just to protect their neck while sleeping or during moderate activity, but it would offer at least some additional protection against neck injuries in a crash, rough landing, or during periods of turbulence.

Perhaps crush injuries are more likely with the baby strapped to you, but honestly I would be more worried about a parent holding their baby being more likely to drop them in the aisle during an evacuation, which would be more likely to endanger everyone behind them on the plane as well.

4h agoHN ↗

I think this is very true. the general consensus from NCPS techs we've talked to is that the most likely fatal injury to a child is spinal - their heads are extremely heavy relative to the rest of their body in infancy so the 'safest' seats tend to be the ones that distribute kinetics away or absorb it (like rear-facing seats where the sudden 'stop' pushes into the seat rather than having the baby's head fly forward)

that said, I've also heard that the US standards for car seats is piss poor relative to the rest of the world's. something about how they only test one head-on crash at 35mph and then extrapolate all the data from there. Germany's ADAC is supposedly the gold standard and I can see why - their tests are intensely comprehensive and granular, in the way you'd actually want them to be, and many of the seats rated safe by American standards fail ADAC: https://www.besafe.com/en/safety-tips/tests-awards/adac/

if there were to be a plane-oriented solution, the last place I'd trust it to be taken forward is in the USA especially given how easily corruptible safety-oriented institutions are here

3h agoHN ↗

I've also heard that the US standards for car seats is piss poor relative to the rest of the world's

How do you define piss poor? The stats show that the US minimum standards still reduce fatal injury risks substantially. And your comparison point for 'rest of the world' is a German automobile club, not a government regulation. Would the better comparison be to ECE R129 for the EU?

something about how they only test one head-on crash at 35mph and then extrapolate all the data from there

You know that the information is readily available and you could avoid spreading misinformation with a 10 second search, right?

The US regulation, FMVSS 213/213A, does a frontal crash at 30 mph as well as a side crash test at 30 mph. For apples-to-apples comparison, the EU regulation does a 31 mph frontal crash test and a 19 mph side test. All of the governmental tests are done on a standardized test bench. The German auto club test is 40 mph frontal and 31 mph side, done in a regular car.

There are also organizations in the US that do testing and ranking beyond the regulatory minimums.

1h agoHN ↗

I mean, you're right about side crashes but I'm reading that the NHTSA didn't implement this until 2022. and regardless, if all that were true the infant mortality rates per capita from car crashes would prove your point

so what do those stats say vs Germany, Sweden, the EU average? all very easily searchable, no mechanistic theorycrafting required. how does the US fare? certainly not multiple times worse across the board, right?

40m agoHN ↗

if all that were true the infant mortality rates per capita from car crashes would prove your point

Would it? How much of the statistics are attributable to a difference in standards vs the higher average speed and larger average vehicles in the US? Physics is a harsh mistress, both of those factors have a lot of effect on crash energy.

1h agoHN ↗

IMO it's not necessarily unreasonable to use standards/evaluations set by a private industry group for this kind of thing.

US automobile safety ratings/improvements over time are largely driven by IIHS (Insurance Institute for Highway Safety). It's a private group but is the standard yardstick manufacturers expect to be tested against and fills in a lot of gaps in NHTSA official crash tests.

It wouldn't be strange to see IIIS plus NHTSA criteria used colloquially to describe "US crash standards" when talking about cars even if not fully defined by regulation.

"UL Listed" products or the International Building Code (the base model broadly followed with modifications by each state) are also "national standards" but not set by regulation.

2h agoHN ↗

The vast majority of the rest of the world simply doesn't use car seats at all. Even here in the US, in my very multinational city, I only see one demographic that consistently uses car seats at all, regardless of economic status.

2h agoHN ↗

Sometimes, I wonder what the societal costs of the ever increasing car seat requirements are.

I wouldn't want a third kid just because I don't want to deal with carseats anymore.

1h agoHN ↗

I wouldn't want a third kid just because I don't want to deal with carseats anymore.

By the time you had your third, would the oldest still even be in a carseat?

But even then, three car seats is doable even in small cars: https://www.jefftk.com/p/three-car-seats

1h agoHN ↗

I meant that I do not want to deal with taking a kid in and out of car seats, or traveling with car seats, or taking them in and out of cars, for more years of my life.

43m agoHN ↗

I work in child car seat development and I can second that the main issue for our mechanical engineers is preventing neck injuries. Rearward-facing car seats really are a lot better on that front.

ADAC is indeed the main test, but even more difficult than getting a good ADAC score is passing the plus test[1], which focuses on neck spinal forces.

Logically extrapolated, in this scenario, the airline becomes responsible for the baby's wellbeing. And I don't think that's a good place for the airlines to be?

Aren't airlines responsible for the well-being of everyone on a plane? That seems like it kind of goes with the territory of charging money for hurtling people across the sky in a giant metal box.

4h agoHN ↗

I think this is ill-phrased, but true. It isn't about being responsible for wellbeing, it is about legal liability in case of accidents.

If you (as the airline) did what the rules where that everybody else follows and the FAA mandates and the baby dies you can argue you did everything correctly and the rules are at fault.

If you however go your own special, non-FAA-approved solution, typically the burden of proof that this special solution is at least up to par with existing certified standards is on you, the airline and if a baby dies it is on you alone to defend that solution.

Meaning from the standpoint of an airline there is not a lot to gain, but much to lose if they do things outside established standards.

This may sound idiotic, but it also prevents other "creative" solutions where airlines sacrifice safety willingly to spend less money.

3h agoHN ↗

I don't disagree with that. To me, that implies that there should be better established standards. The parent comment described some of the mechanisms, but stopped short of suggesting that they become standard, which I think is why I was sort of confused.

3h agoHN ↗

This may sound idiotic, but it also prevents other "creative" solutions where airlines sacrifice safety willingly to spend less money.

Everyone loves to say this from the comfort of their arm chair somewhere in an ivory tower but literally every aviation and adjacent workplace has a phrase to the tune of "here we cut stupid corners, cutting smart ones is illegal"

Which is to say, the do-gooders in their infinite wisdom have blocked progress on various axis, some of them no-brainers, some of them the most reasonable ones, because once upon a time someone took it too far and something happened. So all investigation of where to save money, where to find improvement, etc, etc, happens on axis of optimization that are frequently absurd. This is where most of the "creative" solutions you deride come from.

4h agoHN ↗

Yes, but it wouldn't necessarily be easy to use or consumer friendly. The ideal solution would have the baby with their back facing front, and the attached carrier facing inwards towards the seat.

There is an existing international standard (ISO 13216) for child safety seats in cars:

* https://en.wikipedia.org/wiki/Isofix

Fun fact all these rules act as contraception. Who wants to have a third child when you can’t actually squeeze three car seats into the back of a car.

That’s great? You shouldn’t have kids if you can’t stand the slightest temporary inconvenience such as… providing them safe transportation.

Got any data to back up the fact?

I got anecdata of people shopping for gargantuan 3-row SUVs so they can accommodate the third child seat. Most people don’t seem to mind as it’s “only” a monthly payment. (Over 8 years it’s a fortune in interest let alone the actual cost of the vehicle but most people don’t think that far ahead)

Yeah but people like suvs :) thats why there are fewer minivan and sedan choices these days.

A minivan cost $60,000 more practical would be smaller car seats.

To add my and data as someone who recently got a third child: number one question i get askes is whether we are going to move (we live in an apartment in the city) number two is a comment about cars size. So I am pretty sure people consider this when they think about having another child.

For soft babywearing carriers, the outlook is also grim. The kinematics of the baby, adult, carrier and airplane seat lead to crush injuries that are worse than the poorly restrained arm hold version.

The point is that the "return" - in a vanishingly tiny number of cases, the kinematics is very slightly better (maybe I buy that it is slightly better, without doing research, but it can't possibly be much better) - is not at all worth the "investment" - every single parent of every single baby on every single flight having to put up with a very real annoyance.

how common are airpoane crash injuries?

4h agoHN ↗

There is a deeper issue, in a crash,

you'll be dead so it won't matter much.

2h agoHN ↗

The vast majority of airplane incidents with injuries are not a total loss with most people dead.

Hard landings, rough turbulence, runway excursions, etc are far more common and also situations where differences in restraints make meaningful differences in outcomes.

4h agoHN ↗

Most airlines offer bassinets for babies. You can only get them in front rows where they get attached to the wall in front of the seats. They’ve got a mesh top that your supposed to keep zipped up while the baby is in there.

4h agoHN ↗

Bassinets are only available in the wide-body airplanes, and only a few select domestic US routes are even flying those. And even then, the plane bassinets are tiny, and most infants outgrow them by 6mo. And purely anecdotal observation is that most flights I've been on had way more infants in the cabin than places to install bassinets.

Worst comes to worst

I only ever heard/said this. Seeing it in print, I suddenly realize it must be "worse comes to worst"

There is an easy and FAA-approved child restraint system called CARES. My wife and I purchased one and used it with great success. The flight attendants had never seen one, so it comes with a card for you to show them.

https://www.amsafe.com/kidsflysafe-com/

3h agoHN ↗

Haven't you got pushback that it blocks the tray table of the seat behind you? I've only heard very mixed things about CARES.

3h agoHN ↗

It did work with the tray tables at the time (underneath, while open or shut). This was about 4 years ago when we last used it. Passenger behind us was more curious than upset.

2h agoHN ↗

We actively use ours and it's never been an issue. Simply, lift the tray on the chair behind you, slip the harness over, and close the tray. Normally, families with small children get to pre-board, so we have it setup before the other passengers have arrived. Even after, we've never had any push back.

Notably, though, German carriers like Lufthansa do not allow it, which I believe is due to German regulations. Outside of that, we've never had an issue in either the U.S. or Europe, but occasionally we need to show the airline a copy of their policy from their website on one of our phones. They weren't mean about it, but may not have seen one. Generally, the senior flight attendant is experienced enough to know the rules.

Our kids were huge, so we used it from before they were a year old and it has been very helpful.

CARES is for a completely different group of kids than TFA - infants vs small children...

a poorly secured rigid baby carrier seat becomes a potentially lethal projectile

Rigid carriers are already permitted on planes, as long as they're FAA approved (which many are). You attach them with the seatbelt, and the flight attendants check.

What I'm proposing in this post is that the FAA not require parents to remove lab infants from babywearing carriers.

3h agoHN ↗

From the comments here, many people don’t get the difference. If you’ve never flown with a kid, there is a nuance that is easy to miss.

I was going to make a comment earlier about how my kids travelled in car seats years ago before I realized you were talking about lap kids without their own seat.

3h agoHN ↗

Any suggestions on how I might clean up the wording? Currently I have: "In fact, one specific place where I'd like to see this thinking applied is adjacent to this rule: babywearing carriers on planes."

3h agoHN ↗

Maybe just include an example picture/diagram?

2h agoHN ↗

1h agoHN ↗

Good idea! Changed "Carriers" to "Babywearing Carriers"

1h agoHN ↗

I'm surprised at the amount of people here confusing carriers with car seats. It seemed obvious enough to me in the article. It's about wearing babies on the plane, not babies sitting in their own seat.

1h agoHN ↗

There indeed seem to be a lot of folks commenting who think being able to safely have a car seat on a plane would be a revolutionary change, when that's the part that's a solved problem.

It isn't that surprising given that hackernews tends to skew tin demographics towards young men. And people who don't read articles but have strong opinions on everything.

29m agoHN ↗

I've updated the title to include "babywearing" to try to make it clearer.

3h agoHN ↗

I don't think that's actually what the FAA has reasoned.

FAA calls all of these devices, in general, child restraint systems. Rigid seats with harnesses are allowed under FAA rules. The real consideration is blocked egress, since a large, rigid device strapped to a seat could actually make egress more challenging. That is covered in a more subjective advisory circular, which allows airlines to make policy, e.g., it may only be used at a window seat of a non-exit row.

Since FAA just this month has decided to start enforcing a 1992 rule requiring even so much as a paper cup to be stowed before pushback citing the egress concern, we might even expect some new policy on this.

a poorly secured rigid baby carrier seat becomes a potentially lethal projectile

Too smaht for me to understand.

Can you explain your reasoning why is that the case with carrier seats but not with <literally_every_other_hard_object> including human bodies and their skulls which are way sturdier than plastic moldings?

2h agoHN ↗

Humans are restrained by seatbelts, which are checked by cabin crew.

2h agoHN ↗

You're right, I forgot that's impossible with a carrier seat.

1h agoHN ↗

What do you think people are attaching the already approved rigid car seats to the aircraft with?

1h agoHN ↗

The argument, quoted by the GP, is about improperly restrained seats. They are only talking about those.

1h agoHN ↗

The GP also seems to think that having rigid car seats on plane would be a net new thing. They are already allowed and flight crew already check that it has the right certification and is attached correctly - this is much easier on a plane because the only way to attach them is the seat belt versus most seats have at least 3 different ways to attach in a car.

3h agoHN ↗

Can you link your kinematics? Modern science is much closer to the priests of old. Academics leverage their credentials to present untested predictions as science. Their ideas are considered correct because of their expertise and the institutions they belong to, not because the ideas have been thoroughly tested.

This is religion, not science.

2h agoHN ↗

If you have lethal babies and/or lethal rigid carriers flying around an airplane in a crash, I think you've got a severe enough crash that most of these arguments are picking bellybutton lint. I'd vastly prefer the FAA focus on the rulemaking around ensuring that I'm not in such a crash than worry about what happens if I'm in such a crash. The chances that I get into an accident which is severe enough that I get killed by a flying baby, but I would have otherwise survived, are exceptionally low.

54m agoHN ↗

A heavy rigid object can cause injury in regular turbulence. No crash needed. That would be the danger I’d want tested for. And unless the person bringing the carrier is expected to be liable when their carrier injures someone, it winds up being another liability for the airlines.

35m agoHN ↗

Rigid carriers are allowed today, and get belted in. The post is about allowing soft babywearing carriers.

Thing is a rigid car seat is what you ARE allowed.

2h agoHN ↗

a poorly secured rigid baby carrier seat becomes a potentially lethal projectile.

No it doesn't.

1h agoHN ↗

That solution already exists actually. You buy a ticket/seat for the infant and use an FAA approved carrier. For example, the nuna pipa rx is FAA approved for this use.

It's not a popular choice because you have to pay full price for the seat, so lap-carrying the baby can save quite a bit of money. Once the baby is 2, you can no longer lap carry them, so that option goes away. There's FAA approved options for small children for whom the lap belt would be inappropriate that are different from the infant seats.

4h agoHN ↗

What, you don't want to allow Verizon on planes?

5h agoHN ↗

Strongly agree. I’ve been made to multiple times to wake up a sleeping baby that was strapped to my chest and it feels absurd for everyone involved.

4h agoHN ↗

This never happened to me when I had babies, thank god, but I would almost certainly have politely said "no" to this request. It isn't very fair to the flight attendant who is just trying to do their job, to force them to figure out how to handle an uncooperative parent with a sleeping baby, but IMO it's a very reasonable battle to pick. I think essentially every flight attendant would just let it go.

4h agoHN ↗

Flight attendants, like mostly anyone else, have a job to do. Much of their job involves keeping hundreds of people safe at the same time. Not obeying a FA's order is a federal crime and could be a felony.

4h agoHN ↗

I am aware of that, and also would politely reply "no" to being asked to wake my baby up for no good reason. It is extremely unlikely that this would lead to a felony conviction. It would make the flight attendant's life harder, which I would lament, but being politely told "no" by a parent is not the kind of uncooperative disruption that the laws around obedience to flight attendants are designed to avoid. This is not the same kind of problem as running up and down the aisles yelling and being disruptive.

Having said all that, if I thought I could get the baby out of the sling without waking them up, I'd probably try that first though. (I'm pretty sure most flight attendants aren't enforcing this silly rule to begin with, because I'm pretty sure I would have experienced it if they were, I used these slings / carriers all the time, including on planes.)

3h agoHN ↗

a flight attendant was annoyed that my diaper bag was in front of feet instead of in front of my feet by 3 more inches. While feeding a fussy baby as a parent traveling alone, with no hands free, I gave then a look of "are you serious?"...while I proceedes to make my daughter cry quite a bit to shove the bag a bit more.

Just being a flight attendant doesn't make them great humans to be around.

2h agoHN ↗

It is extremely unlikely that this would lead to a felony conviction

Uh, you'd be surprised. Once you refuse, they are going to insist, and if you still refuse to comply, or they're going to return to the gate and have your ass removed. They don't pick and choose which rules to enforce.

And yes, they do enforce this rule. We experienced it all the time when my son was a baby.

3h agoHN ↗

I think essentially every flight attendant would just let it go.

I predict they will not let it go, and it will escalate to escorting you off the plane. It's a violation of federal law to allow you to keep your child strapped in, and the attendant risks losing their job.

2h agoHN ↗

Just be very careful with this. Flight attendants have the force of law behind them and you never know when they'll decide the right way to handle an uncooperative passenger is to have police meet the plane when you land.

5h agoHN ↗

If they do then I hope there is an additional rule forcing the guardian to purchase an adjacent seat, so there's no risk of someone (me) being guilt tripped into swapping seats.

5h agoHN ↗

This is addressed in the first paragraph of the article.

The FAA has one of my favorite examples of thoughtful rulemaking. They haven't banned flying with a baby on your lap, because the extra cost would mean many parents would drive instead. Since driving is far less safe than flying, a ban would lead to more deaths. I'd love to see more of this "all things considered" thinking around bans.

5h agoHN ↗

This is extremely dubious logic with very bad stats.

Vast majority of accidents happen on regular driven known routes not road trips.

I would expect far better from the FAA.

4h agoHN ↗

Vast majority of accidents happen on regular driven known routes not road trips.

It is possible for this to be true while also simultaneously it being true that road trips are more at risk of accidents than regular routes.

Vast majority of accidents happen on regular driven known routes not road trips.

I always heard people say most crashes happen close to home and I never thought twice about what they were actually saying.

Then one day it hit me: most people don't regularly drive far from home, so of course of accidents happen close to home.

4h agoHN ↗

You can't circle around this because simply put per million miles flew the fatality rate is significantly lower than that of driving

3h agoHN ↗

Most accidents happen close to home because most driving happens close to home it says nothing of the risk of road trips - I expect better from HN commenters.

4h agoHN ↗

This sounds like a different problem than the one this post is about. For baby-in-lap, no one is being guilt tripped into switching seats because the baby doesn’t have a seat.

If you’re being guilt tripped into switching seats so that a family with a young child can sit together, consider blaming the airline for not automatically seating a young child next to their guardian.

3h agoHN ↗

Blame the airline for not automatically seating people who buy tickets together... together. It's just a trick to get travelers to pay extra.

3h agoHN ↗

It’s absolutely a trick to get travelers to pay extra, but I can grudgingly accept the nickel and diming when my party consists of adults. When one of the members of my party is a literal 3 year old, it becomes ridiculous.

5h agoHN ↗

I prefer the Fran Lebowitz suggestion : a separate plane with no seats for children, they can float round the whole trip from takeoff to landing. also let's option the adult plane with opening windows so we can smoke again.

here's the /s for those of you who are tonedeaf.

5h agoHN ↗

It's only fair, since they allow planes on aircraft carriers.

4h agoHN ↗

Would that lead to a fractal of planes and carriers?

4h agoHN ↗

When I read the title I thought it was referring to communications carriers (cell phone companies.)

4h agoHN ↗

As a parent of 3 kids and an extensive baby-carrier user, I see your argument but I think you're lacking consideration of the failure modes.

Yes, almost every baby carrier would likely restrain the infant better than add-on infant belt if the adult lap belt rides up over the infant carrier, the infant's going to be crushed between the adult and the belt. Not a good outcome.

Thus you're likely going to need FAA-approved infant carriers, same way as you'd need FAA-approved car seats you can take on planes.

4h agoHN ↗

I dunno, I flew UK-IRL this summer and in both directions I just threaded the baby-belt (standard issue here, the cabin crew hand them out before the safety briefing) around the carrier and the sleeping baby.

In a full on crash situation infants are not going to do well, so optimising for much more likely turbulence injuries (for which having the baby strapped as securely as possible is definitely a good idea!) seems more important.

4h agoHN ↗

You're doing perfect is the enemy of better.

4h agoHN ↗

It's been awhile since I used one so maybe I'm misremembering, but isn't the brace position for a lap infant basically the same as what a rear facing soft baby carrier does naturally?

It seems strange to disallow the carrier, have the belt that loops through the adult belt but then if the plane is going down you have to get them into the same position they'll be in in the carrier anyway!

4h agoHN ↗

Relatedly, I wish I could bring my electric wheelchair with me in the cabin. I went on a work trip to Paris in April and sitting in a regular seat was just as uncomfortable as I remember. Fortunately, halfway through the first flight one of the attendants noticed my caregiver frequently repositioning me and had the other person in our row move elsewhere so that I could lie down across two seats. American Airlines allowed me to do that on the return flight as well.

I was quite worried that my wheelchair would break in some way like I've experienced several times before but everything went quite smoothly! AI helped tremendously with planning, e.g. here's Claude: https://claude.ai/public/artifacts/6c977d23-1b7c-4a00-a7aa-d...

4h agoHN ↗

Oh no, you have to take your baby out and hold it during all the times when you have to have everything stowed and can't do much of anything else anyway, whatever shall we do, won't someone think of the children? This is a non-issue, and not worthy of a blog post.

4h agoHN ↗

People are free to write whatever they want on their blogs, and you are free to not read their post or comment about it.

I really don't understand people who accept inconveniences for themselves or for other people without any interest in examining whether those inconveniences are serving any useful purpose. Everything like this should be interrogated. Yes, most things don't matter at all, but we still shouldn't do them if they're dumb. Some things - like this example - matter a bit more. It's not the end of the world, but waking up a sleeping baby can easily ruin the rest of a family's day. If there is a good reason for that, then no biggie, if the reason is nonsensical, then no.

4h agoHN ↗

The FAA has one of my favorite examples of thoughtful rulemaking. They haven't banned flying with a baby on your lap, because the extra cost would mean many parents would drive instead. Since driving is far less safe than flying, a ban would lead to more deaths. I'd love to see more of this "all things considered" thinking around bans.

In terms of CO2e, a familiy of 2 + a kid driving a car instead of flying results in quite a bit of less emissions. Depending on the assumed mortality per tonne CO2e, driving might lead to a lot less deaths.

This is of course quite unreliable data, but one example of just to say how "all things considered" is very hard and almost always still comes down to a judgement call.

4h agoHN ↗

Of course, not everything needs to be decided by the FAA. Sometimes they could let people make decisions for themselves.

3h agoHN ↗

Yes. This. We all - and especially parents - spend all day every day evaluating risks. The FAA does not need to decide for me the level of risk between holding a baby in my arms vs having it in a sling during take off and landing. That's very silly.

2h agoHN ↗

For real. For something like car seats, arguably the regulation was what we needed to get them adopted. This though, seems as necessary as government regulators deciding if I can babywear my child when walking down the street. The relative risks and benefits are impossible to fully compare with this issue, and the impact on other people is nil whether it's baby in lap or baby in carrier.

4h agoHN ↗

I think what’s better is modular seats. The interior of the airplane is empty with harnesses all over the floor, and based on the passengers the seats get customized. A baby? A carrier seat is put there. Disabled? They can use their own as long as it fulfills the specs. Fat person? Combo seat. Someone wants to sleep? A bed-like is added, and so on. Plus the arrangement inside can be easily reshaped for best experience

4h agoHN ↗

How much time are you imagining the crew have got between flights to tidy up the plane for the next flight?

4h agoHN ↗

It’s not a big issue, by the time they are loading/unloading the luggage, it can be done. It should be designed in a way that can be easily attached or detached, or even automated/robot based rails does the job quickly.

So for example: while booking you get to select those options, and while they load the luggage, an app on some crew tablet quickly arrange the seats and hit submit, the rails automatically do the jobs! Ycombinator, prepare that VC funds!! ;)

3h agoHN ↗

They get 22 minutes on most US domestic flights and that includes deboarding.

3h agoHN ↗

I don't know what your flying experience is, but mine is that you're lucky if the cleaning crews have a chance to make a quick sweep of the cabin before the next flight's occupants begin loading. I'm usually towards the back of the plane and the cleaning crews are already 10-15 rows into the plane by the time my row can exit.

There's no way, in my experience, that they'd have time for something like that. Especially since anything that moves will invariably have mechanical issues from time to time. I've had to sit in a broken seat before because they simply do not have time to fix it between flights.

4h agoHN ↗

From sled tests done by Australia in 2022:

A lap-belt restrained adult dummy in an aircraft seat, with an infant dummy in a carrier, was subjected to a 9G dynamic sled test. The severity of the pulse was based on the results of a static load test. The commercially available infant carriers tested were not able to restrain infants under crash situations.

https://www.atsb.gov.au/publications/research-and-analysis-r...

3h agoHN ↗

The missing comparison is to a parent holding the baby in their arms, which I expect would also fail a 9G test. We're not making babies safer by requiring parents to take them out of babywearing carriers.

3h agoHN ↗

Exactly. There is no way most parents could keep ahold of a child during 9Gs, unless they have the grip strength to lift several tons.

4h agoHN ↗

Personally I think babies shouldn’t be allowed on planes.

4h agoHN ↗

Tangentially related ... US school buses don't have seatbelts.

3h agoHN ↗

I think this is a way that airlines and the FFA could continue to grow in consideration. At some point the economics of flying with children starts to make less and less sense. I just flew with a toddler that was under 2 from the mainland US to Hawaii and back. The toddler is just under 2 so he was considered a lap child to fly free. However at 2 the child for most airlines graduates to a full price ticket. At that point it seems less and less likely for families to want to fly over driving. Then add more children you are spending something of a small fortune to fly anywhere. It seems like the airlines could capture more business if they could price into their model a discounted ticket for children older than 2 but under a certain age (ie. 13 or 10).

3h agoHN ↗

But why? They weigh slightly less, but take up a seat. Why should a child be subsidized. Planes are typically full or close to full. The airline doesn't really care what age the butt is in the seat, just that it's a revenue passenger.

3h agoHN ↗

Yeah, and as someone who just travelled with three young kids I don’t think my party cost the airline less than our number of seats, probably a lot more. We required more attention from staff, made a bigger mess, and didn’t bring less stuff per person just because the kids are small.

Kids are already subsidized with free gate checking of strollers (to be fair, so are other things like skis on Alaska).

35m agoHN ↗

You all have some fair points. I was thinking about it as more of a business opportunity for the airlines to attract more families to fly over driving. As I said before the economics start to become more prohibitive to fly vs driving the more passengers. Its not unreasonable to think this way. Airlines give out other incentives for loyalty or just generally having enough airline points. Why not like family packages to attract families that wouldn't otherwise go to get more business

3h agoHN ↗

If people decide to have children, they should adapt to the world; expecting the world to adapt to them is insane.

I have a unique perspective on this as a former federal rulemaker. One thing you should know is that when it comes to rulemaking, the FAA isn't an ordinary rulemaker--they do the most of it and they're the best in the business. When I went to my intro to rule making classes, the FAA always rolled deep.

If you want a change and you want to make sure the right people see your request, I suggest you start here:

https://www.transportation.gov/regulations/petitions

3h agoHN ↗

Why doesn't the FAA usually implement the changes the NTSB raises after learning from crashes?

They do when appropriate after considering all concerns. The NTSB is solely concerned with safety. The best rulemaking is not literally safety-first or nothing would actually get done.

2h agoHN ↗

As a student pilot, I got confused by a sign in the aeronautical charts, and wrote to the faa.

I got to present in front of the aeronautical charting group, they discussed, and took up my change. It was a surreal experience. The level of depth, care, and just breadth of considerations to flip every possible stone to make flying infinitessimally safer was truly awe inspiring. The fact that me, a at-the-time-not-yet-even private pilot, was heard and taken super seriously, was equally amazing. Fully agree -- these people are the best in the biz.

I'm OK with it if the carrier can be hermetically closed so that no sound can escape from it :)

2h agoHN ↗

We should also allow window seat people to have their table down during take-off and landing. The only reason for it is delaying evacuation but in window you only delay yourself. Makes no sense to mandate that.

59m agoHN ↗

Absolutely not. Ban all babies on planes. Or at least in biz class. Many flights I have taken have been ruined by a crying baby. The pressure, the claustrophobia. The baby is very uncomfortable.

Don’t bring them, you are ruining everyone else’s vacation.
