The FAA says it. "The FAA does not require the use of CRS's on commercial airplanes".
It was in response to the question "Does the FAA require children on commercial flights to be in child restraint systems (CRS)?"
That is a broad question, and I stand by my understanding that no child must be in a carseat on an airplane.
Do I feel it's insane for a little one to NOT be in a seat? Yes. Even though we did the lapbaby thing for one roundtrip flight (and I was dreading the way home but had no extra money to buy DS a seat), I now realize how dangerous it was.
And DS was in a carseat on the plane until he was 3.5 and I just couldn't deal with bringing the seat on a half-full plane, and the gate agent asked, again, if I wanted to check it and I said yes.
But the FAA, as well as all FAs I've ever talked carseats with, has stated that there is absolutely NO rule/law that any child needs to be in a CARseat on an airplane. They just have to be in the lapbelt.
Perhaps some flight attendants, who deal with the public, can chime in?
Found the 2005 news release where they announced the
change.
