I an not worried about BD following suit as they have put out their position on the letter I got on 2/28/11 and just opened. It noted that 100 miles per $1000 up to $200000 which is the norm. then it goes on with more language for amounts over that. I would not expect to see a change on AA miles status from them for 6 months to a year after a letter this detailed. They do not have brick-and-mortar infrastructure so their costs have to be lower overall so they are likely going to keep the loyal AA customers and get some more from the bank making the change.
