I have done with and without carseats on the plane, when dd was 1 it helped her sleep on the plane, other than that, I decided it wasn't worth it to drag my car seats on. I'm a car seat fanatic as well, and my 6 yr old son is not allowed to ride in anyones car without a 5 pt harness still. I keep my arms across them when landing just as a 'mom' thing I guess.
About gate checking car seats, we did this several times, and then last trip with AA we were told we couldn't gate check them (at the gate) and that we would have to go all the way back out and check them as luggage. I was almost in tears because that would make us miss our flight! Finally the lady decided to let me get by with it 'this one time' and let us gate check. SO please check with your airline about gate checking. When you do check them as luggage make sure they have a cover on them, and they don't have any checked baggage fees applied.
About ON the airplane with kids. I agree about giving kids decongestant (recommened by our ped), you can take this in a carry on, just make sure to tell them at security that you have liquid childrens meds with you.
Also Lollipops help at take off and landing for the sucking, and it helps keep the kids quiet for a few minutes
Take kleenex with you to blow their noses during takeoff and landing..we do this every minute or so when ear pressure builds, it helps to pop their ears. The 6 yr old may be able to pinch his/her nose and blow very gently.
DVD's are great! Alot of people use their laptops for dvd players on the planes, but we have taken a portable dvd player as well, whichever you prefer! We let the kids each take a backpack with coloring stuff and other small toys, and they have a blanket in the backpack also (airplanes are often cold!). We have snacks divied out for them and easy to grab.
My kids just love being on the airplane! I hope you have a good trip!
