Thanks to Frequent Flyer Bonuses for sharing the new Hyatt 2014 summer promotion. From May 1, 2014 to Aug 31, 2014, you can earn triple airline miles for each stay after the first stay for a max of 15 stays. For example:
Stay 1=500 bonus miles
Stay 2-15=1,500 bonus miles per stay
Below are each participating airline you can register for. You can only register for one and when you earn airline miles, you cannot earn Hyatt Points; however, you still will be able to earn credits towards status. I’m assuming cash+points will also count towards this promotion.
Air France/KLM Flying Blue – Registration
American AAdvantage – Registration
ANA All Nippon Mileage Club – Registration
British Airways Executive Club – Registration
Japan Airline Mileage Bank – Registration
Jet Airways JetPrivelage – Registration
Lufthansa Miles & More – Registration
United MileagePlus – Registration
Also here is a post of how you can maximize your savings on Hyatt stays.
