If you're travelling by plane, you have two options. One, buy, wrap, and ship all your gifts far enough in advance that Santa (and UPS) can deliver them on time. Or two, get super creative with what constitutes a gift. Going to the beach with a kid who's grown two inches since the Summer? Guess who's getting new swimsuits and sandals!? Flying across the country to see the grandparents? Bring on the gift cards! Compact, packable, and functional are on your wish list.
