Yet Another Way to Earn Miles

We've all done it. Forgotten that we had a gift card to a retailer or never used the full amount on the card. Now you're left with funds that will most likely go unused, money down the drain. Well, if you're a United MileagePlus member, you are in luck.

United Continental wants your unused gift cards...and in return, you get miles.

Sounds like a pretty sweet deal to me.

The airline just launched a new program that will reward members of its frequent-flier program with miles in exchange for their unused gift cards. United said the program was the first of its kind.

There are more than 60 retailers participating--Barnes & Noble, Home Depot, Pottery Barn, to name a few. Members just log on to their accounts, find the retailer for their card and enter the information. The amount left on the card will be converted to miles and deposited in their account. There is a minimum balance of $25, and cards cannot be combined to reach that limit.
