@alarmguy , as I have posted before, you are a master of the credit card explotation game. 99 percent of the American population can't do or accomplish what you do with credit cards. If a minority percentage of credit card users accomplished what you accomplish with your credit cards, these two percent cash back offers and the like would be very uncommon.
I have a lot more to do in life than play credit card reward games and rebate games. Not a hit on those that invest the time to play those games, just not a match for me.
As far as Citibank and Barclays. American Airlines is under duress in many ways at this time. I am typing this sitting on a American Airlines 737.
American Airlines had a good and balanced partner with Barclays. I loved my Barclays card and their customer service when I occasionally needed it. Now American Airlines partners with what is arguably the most nastiest major bank in US history. Not a good way for American Airlines to motivate a flyer like me to want a American Airlines credit card.
Of note, in the last year I cancelled my Citibank American Airlines credit card after having it for I believe two decades. I never used the card, but kept the card for the Admiral Club membership. Th annual fee on the card was nearing $1k USD annually, so I decided to just pay directly for Admiral Club membership.
On a side note, many iof my peers and myself have Citibank corporate cards. Simply a horrible card, especially if used regularly OCONUS. Customer service beyond brutal.
