Mileopoly posts about a 20% Saver Award Rebate for United Elites that have a Mileage Plus Visa card.
Registration is required.
As a non-elite with United, it did still allow me to register for the promotion. This is more than likely a targeted offer and whether or not that means any miles rebate for me remains to be seen.
The award must be booked between before December 15th, 2010 and must be on United or United Express metal and is good for up to two people on the same reservation. Your 20% miles rebate will be posted to your account four to six weeks after you fly.
