I chalk this one up to marketing going in opposite directions. With the upcoming SM destruction trying to poach O/D ORD-LHR pax from UA, AA, BA is going to be VERY difficult. Instead, poaching by *A or OW for long haul biz in DL hubs is a much greater concern now.
Any pre-existing dreams by DL of poaching ORD/LHR O/D customers from AA/UA hubs in 2015 is a dead letter unless AA/UA make their FF programs even worse.
