http://overheadbin.msnbc.msn.com/_n...h-tv-spend-money-at-the-airport-to-earn-miles If you’re willing to watch a little TV, you could earn thousands of extra miles for your airline frequent flier account. If you’re buying a book or getting a massage at the airport, you could earn even more. Here are two easy ways to bulk up that mileage account: e-Miles, which has been around since late 2006, currently offers miles on Continental, Delta, Frontier and US Airways, and points for Hilton Hotels, in exchange for watching 30-second ads online. In addition to the miles you get for watching the ad and answering short surveys, you can squeeze out extra miles by clicking through to an advertiser’s website or, of course, buying the product or service being peddled. If you’re already at the airport, there’s a far easier way to bank extra miles. Many parking, dining and retail outlets in more than 100 airports in the United State participate in the Thanks Again program. Travelers who register their debit or credit cards (even affiliated ones that already offer miles) can earn cash back rewards and miles for purchases. Participating airlines listed on the Thanks Again site currently include Alaska, Continental, United, Delta and US Airways. The latest addition to the Thanks Again traveler reward program is XpressSpa, which offers spa services, product and travel accessories in 41 locations in 16 airports.
