I don't fly often, but when I do, I collect my United miles... I've not used them for anything yet, but this is tempting:
As an elite member, Mileage Plus now offers another satisfying way to redeem your miles. For a limited time, you can redeem miles for Dining Dough, a leading provider of dining certificates. Redeem as few as 1,000 miles for a $25.00 certificate or 5,000 miles for $125 in certificates?valid at more than 6,000 restaurants nationwide!
Enjoy Dining Dough in your hometown...or the next time you touch down at your favorite United domestic destination!
