I fly tons with Aidan and have since his birth. Make sure you pee in the airport. It's best to gate-check your stroller and car seat. DO NOT check it with your luggage. I gate-check the car seat to my final destination, but if I have a layover, I gate-check the stroller to my layover stop. Family Assist bathrooms in airports ROCK. Make sure you have a carrier- mei tais are awesome because you can use them on the front/back. I used my Beco this past trip, because it was easier to carry A on my back in the Beco than it would have been to hip-carry him in the Psling.
