Ok, here's a win-win proposition if you have an American Airlines AAdvantage frequent flyer account that has miles that are going to expire. You can convert miles into dollars in a UPromise college savings account. Each year you can convert up to 50,000 miles. American Airlines will fund your UPromise account with one dollar for every 200 miles you convert. 50,000 miles will become $250.
As an extra benefit the transfer from AA to UPromise will generate activity in your AAdvantage account which will update your milage expiration date for any miles you may have subject to expiration.
