I am fond of Cartier Roadster Sport, but I haven't seen it in duty free shops yet. Burberry London is a duty free favorite, but it sounds like you probably have sampled it already. You can find Chanel Egoiste, not the Platinum version, in airport shops. But that's more than two years old. How about Dior Fahrenheit 32? Chanel Allure Homme Blanche?
