I have had an AAdvantage Visa since 2002, after they technically "stopped offering" it. I have always preferred Visa because of international acceptance. When I signed up, they said that when it expired, I would be switched to a Master Card. They just renewed it again, with no attempt to move me over to Visa. Admittedly when I signed up, I had to forfeit some miles (I think it was 10K for Visa, 12.5K for MC or something like that). I definitely don't receive 2 miles for AA purchases.
