The problem with this, is when people get Barclays to allow a PC, it is typically them changing a co-branded card into the Rewards card. When I finally got my Apple card PC'd (Called 5 times), I was only offered the Rewards card or Apple with iTunes rewards.
Are you looking to get the card with the AF? Because I think most lenders make you wait til 12 or 13 months to change AF cards.
I have a Barclay Rewards Card and wanna change to Barclay Arrival!! is there a possibility to do that??
Usually a PC doesn't get the signup bonus. So you would be losing 40,000 miles because you are not applying for a new card.
