- For every three stays at SPG properties (W®, St. Regis®, Sheraton and more) from May 1 through July 31, 2010, you’ll earn a Free Weekend Night Award redeemable through December 19, 2010.
- For every stay at Sheraton hotels in North America (United States, Canada and the Caribbean) from May 1 through July 31, 2010, you’ll earn 1,000 AAdvantage® bonus miles.
- There’s no limit to your earnings, so you can earn a wealth of Free Weekend Night Awards while collecting thousands of AAdvantage® miles!
This is a pretty sweet promotion if you are already going to take AAdvantage of the SPG free weekend night promotion. There is also a 3,000 American Mile promotion for every Hyatt stay, which is better in my opinion, and a 5,000 Delta Sky mile promotion with every Marriott stay.
