Called in today to inquire about upgrading from Red to Silver and was told that it will be available July 1 after the merger goes through and to check back then. I believe the merger for Barclays is the conversion of all current US Airways Mastercards to the AA Aviators Card since AA & US have merged the mileage programs already and have already received the "single operating certificate" from the FAA. Maybe Barclays wants to get everyone on its Aviators Platform before going forward.
