Reply #128: I took my two year old on a three-leg cross country flight

then did the same thing home a week and a half later.

He slept through most of it, because I kept him awake and busy as long as possible the day before. When he was awake, he snacked, looked out the window a bit and was really well behaved.

I think the big tricks are to have plenty of food and snacks so there's no ear pressure trouble or hungry bellies, and to make sure the kid is at any age in their own seat and in a carseat- that way they're in a familiar space where they already know the rules.
