i detest flying, but i love to travel..
usually we are with 3 kids in tow, so my choices are easy and not messy, but they work. string cheese, yogurt, dried fruit, veggie sticks with dip, and pb and j sandwiches, triscuits, etc. i tried sushi once, my 9 yr olds favorite food, hit a rough patch in the air...soy and wasabi everywhere. eat what you need to and save your appetite for real food when you get there.
