You didn't mention it but I am assuming that you are actually purchasing a seat for your son? I know that you don't HAVE to up until the age of 2 but I wouldn't DREAM of traveling with a baby/toddler who didn't have their own seat. It is, first of all, completely unsafe (I can't believe they even offer this option) - they can bounce out of your lap so easily. Secondly, the thought of holding him for the entire trip is horrible! We travel A LOT (in laws are overseas) with our 4 kids so all I can say is bring his car seat and stroller right to the gate - make sure your carseat is FAA approved (the flight attendants sometime check them and make a big deal out of this). We always travel with portable DVD players and favorite movies/shows. Lots of snacks and high hopes that he sleeps for most of it - the time of the flight is important (we like to fly at night into the a.m. so there is sleep involved). I don't think the airline makes a difference - being well prepared does! Best of luck!
