Aviator Red (#1 for me, as I have 2 Red cards): AF hit on 10/31, called tonight. AF waived and given the offer for 5k miles for $1k/90 days. Accepted. Only about $5k in spending in the past 12 months, which was to hit a previous bonus offer. Haven't used the card since January.
Guess I'll repeat this charade in March/April with card #2. They recently sent me an upgrade offer to the Aviator Silver on card #2, but I have no interest in it.
