AA had a great program they ended last year. I had that card for years, it really wasn’t your typical credit card, but it was a card where you could pay for your tickets over 6 months interest free, which worked out great for my wife and I. I had that card for over 20 years and used it probably 75 times through the years. Not sure why they ended it, just got a letter last year saying it would no longer be available.
