Never travel without a book or two, a deck of cards or some small non-electronic game of some sort, and snacks such as trail mix, peanuts, granola, or breakfast bars. We seldom fly anywhere, we drive to where we want to go, but the same holds true even more so for car travel. When traveling with children I always pack a "goodie bag"---snacks, crayons, activity books, small magnetic games, etc. It just makes for nicer trips. I even pack one for myself--- projects that need hand sewing, quilting magazines or books, snacks, etc. I really feel for these people and can't imagine being stuck in an airport for days on end.
