One of the prizes in the American Airlines 40th anniversary game and sweepstakes is 20% off a Hyatt stay. American and Hyatt launched a double dip partnership two years ago.
When you win the Hyatt prize though it’s not 20% off a single stay, instead you’re sent a coupon code for 20% off the standard rate at a specific set of hotels which is usable by anyone and reusable. Here it is.
