Airport stores are no longer just for duty-free products. Rather, today's travelers are treated to selections ranging from high-tech toys to high-end fashion. Here are 10 of the world's best airports for putting a dent in your wallet.

Changi International, Singapore
Changi is the largest retailer in Singapore, and the store consistently ranks number one among airport shopping experiences worldwide. The emphasis is on luxury goods, with outlets for names like Burberry, Hermès, and Chloé (which opened its first-ever airport boutique here). In Changi's stores, travelers can get serious and plunk down $8,000 for a limited-edition bottle of Rémy Martin cognac sporting a diamond-embedded stopper or, like one shopper did while waiting for a flight, drop $100,000 on designer jewelry. www.changiairport.com

John F. Kennedy International Airport, New York
An impressive number of upscale boutiques, including Ferragamo and Bulgari, can be found in JFK's multiple passenger terminals. Whether you want to pick up a jeweled Bohème fountain pen to use while you're working on our crossword puzzle, an 18-karat-gold Roadster watch from Cartier to keep track of the current time zone, or a coffee-table tome about Botticelli from the Met Store, it can all be found right here. www.kennedyairport.com
