Beginning June 1, and ending August 31, guests at Comfort Inn, Comfort Suites, Quality, Clarion, Sleep Inn and MainStay Suites brand hotels in the U.S. and the Caribbean can earn 500 American AAdvantage miles per stay, instead of the standard 250 miles. Guests at Econo Lodge and Rodeway Inn brand hotels can earn 300 miles per stay, instead of the standard 150 miles.

This promotion follows an earlier Triple Miles promotion with several other airlines and reminds us that miles aren’t just the reward currency of Marriott and Hilton. Considering the average daily rate of these hotels — this may be one of the best bonus ratios to dollars spent of any current bonus offers.

Fine Print: To receive double miles, guests must stay at a qualifying rate and provide their American Airlines AAdvantage number upon check-in.
