American Airlines has informed us that as of tomorrow June 5th, AA will be removing the ability to view X & R upgrade inventory which will affect channels, including ExpertFlyer.com. Here is the official statement from American: As such, starting tomorrow X & R classes will be removed from the AA Award & Upgrade search. In addition, any Active Flight Alert for X or R on an AA flight will be changed to Expired. Please note this change does not affect A/C inventory, only X/R. There is currently a thread in the AA forum on the subject here: http://milepoint.com/forums/threads/no-more-x-r-upgrade-inventory-visibility-expertflyer.37404/ Thank you for your understanding in this matter and continued support of ExpertFlyer.com
