That is still on the table, but no details yet.
After linking their World of Hyatt and AAdvantageŽ accounts, certain World of Hyatt members with World of Hyatt Explorist elite status or higher may, from time to time, be selected for the opportunity to participate in offers to earn AAdvantageŽ elite status by traveling on eligible American Airlines flights during the designated offer period.
Check your AAdvantageŽ account page to see if you have been selected for the opportunity to participate in an AAdvantageŽ elite status offer, and, if so, for further details on AAdvantageŽ elite status offer opportunities. Additionally, American Airlines or World of Hyatt will inform you in the event you are selected for the opportunity to participate in an AAdvantageŽ elite status offer.
