For those flying into Asia for business, being comfortable during the 20-plus hour flight is well worth the expense. Singapore Airlines has some of the most extravagant first-class features of any airline. Passengers choose between Dom Perignon and Krug champagne, and can have food whenever they want it, whether it is a five-course blowout or a quick bite. Singapore Airlines' first-class experience is all about pampering its fliers. Each first-class passenger is given an exquisite toiletry kit from Ferragamo, and is supplied with sleep suits and slippers from Givenchy. With 82-inch long seats that flatten into beds with sheets, a down duvet, and oversize pillows, you'll wish the plane would never land.

COST: From New York to Shanghai (each way): $8,751.
