I got some Aviator Red BT checks in the mail...3% fee for a 15-month 0% BT...nothing too amazing, but I figured I'd call to see if they had anything better to offer.
Nothing at first, but on checking some other part of their computer system, the rep found +1k AA miles for the combination of $250+ spend in March and $250+ in April. The amounts seemed kind of silly in the context of my overall spend, but I guess it's commensurate with what I've actually put on the card.
Up to 3x AA miles on general spend when I've no other bonuses to pursue and will hit the BBP cap this year? I'll take it.
