I'm also one of the few that never got transferred from BofA to Barclays, so I still have a US Airways Visa from them. Wonder what will happen to that.
Depending on the contracts, we may see some overlap like we did with the HP/US merger, with both Barclays and Citi offering cards, at least for a while.
I'm certain that at this point no decision has been made on which to keep. So like with pretty much everything else, it's going to be business as usual for the rest of 2013.
