I've had AMEX Biz Plat the last 2 years. My annual fee just posted on 12/24, going up from $450 to $595, so I'm planning to cancel the card this month. But before canceling, I'd like to take advantage of the $200 airline credit for 2020 by booking $99 WN flights.
But if I get the credit this week and then cancel the card 2 weeks later to avoid paying the AF, am I risking clawbacks of the credit, or shutdowns of my other AMEX cards, or should I be safe if I've had it open and paid AF the past 2 years?
I know it's risky to play games with AMEX sign-up bonuses, but I don't see anything in the T&C that would be an issue for using this credit. But considering reports of other clawbacks they've been doing months later, I'm nervous about their new aggression and don't want to get in trouble with them. Any advice or DP?
