Aviator Red.
I have two. My favorite one (which is a keeper) with 10K bonus miles with AF paid every year and seems to get the 15K bonus if spend $500/$500/$500 every year as well just before the AF hits.
Then my 2nd, not so favorite. Opened a year ago. No 10K bonus with AF. Never got the 15K bonus offer. Called to close. Retentions made no offers of any kind, no AF waive or any bonus points. Closed card.
