We heard of and ordered a Sit-N-Stroll stroller. It converts from car seat to stroller to booster chair and back. It is FAA aproved and you can wheel it between the seats of the airplane. We got it this week and it s easy to use and VERY plush and comfortable. This way, we can use it at home in one of our cars and not have to lug around a stroller and car seat or rent one. Hope this helps.
