Your decision to book a Christmas morning flight saved you a bundle — and it's a good thing, because you just realized you forgot to cross a few very important people off your gift list (oops). Luckily, the airport is a veritable treasure trove nifty items, and we're not talking the overpriced tchotchkes they peddle to tourists. One quick glance at your airport directory and you’ll know you’ve struck gold: these "malls" offer everything from the snazzy "invention shop" Brookstone to Best Buy kiosks; it varies from airport to airport. Through a quick search, we found totally giftworthy venues including Brooks Brothers (Dallas Fort Worth), Montblanc (Miami), Fossil (New York’s JFK) and the clothing store Mango (San Francisco). Make the most of your terminal sprint by using an app, like GateGuru or Airport Zoom, to view the shops and a map on your way to the airport.
