Why are frequent flyers all over the U.S. suddenly craving cheese? And more specifically, Emmi Swiss Knight Fondues and Snack Wedges? Because recently, with every purchase of specially marked packages, frequent flyers could earn 500 American AAdvantage miles. Yep, frequent flyers from Albuquerque to Tukahoe dusted off the ole fondue set their granny gave them in 1979 in preparation for lots and lots of cheese parties.

The cheese hunt was so popular, in fact, that Emmi backtracked and posted this on their Web site: “Due to the popularity of this promotion, our supply of AAdvantage miles has been exhausted.” They went on to state that if you had a valid offer code, you could redeem for one free Swiss Army Knife — a value of $20. Ouch. But then, magically, the mileage offer came back — but this time, only two codes from two boxes of cheese can be turned into miles — through Jan. 31. See http://www.emmiusa.com
