Ok, so for airplanes I guess it is sort of moot. If your car seat fits and you paid for a ticket (or happen to have an empty seat next to you), I guess you just strap it in as best you can given the only seat belt that is there...not like you can take it to get checked. On a side note, we did have ONLY ONE airline flight attendant tell us if our son was in his child seat, he had to be at the window (I can only assume in case of evacuation so his seat doesn't block our exit).
But for rental cars, what do people do? We are actually in rental cars or borrowed cars while traveling at least as much if not more than we are in our own car (we live in Manhattan and seldom drive, but do have a car). In fact, our 16 month old son has logged about 40,000 air miles.
Since most rentals are new, they likely have the
LATCH system, but is that sufficient? I mean, it isn't like you can go get the seat inspected every time you stop by Avis...
Do people just do the best they can, or...?
