Changing CC
My guess is that I've had lifetime 600K in CC spend and promos, 2.6MM BIS and 2.1MM bonus miles.
At the moment I've got 730K RDM unused and been thinking about switching out of the AA CC anyway. I'm concerned about too many eggs in that AA basket what with capacity cuts, someday not having access to expanded EXP award availabiltiy, AA possibly repricing awards due to fuel costs, maybe even someday a bankruptcy.
While losing 50K of CC spend a year toward the next MM isn't that big a deal, this looks like a good time to switch to a different card anyway.
