Hi guys, I'm looking for hints / tips / advice on flying long distance with a 3 year old & 18 month old. We are going overseas in December for 5 weeks & our flight will be 11 hours there & 13.5 hours back. Mr 3 year old will have his own seat but Mr 18 month old will be on our laps. I have an iPad / iPhone for games & movies (any recommendations here?) with their own headphones. Thanks...
