I think something possible would be something like
$999 Membership Fee
5x Airfare, Hotels
2x Gas & Groceries no limit
2x Restaurants
$250 Airline Credit
$250 Saks Credit
$250 Uber Credit
$250 Hotel Credit
Hilton Diamond
Marriott Platinum
Delta Silver (at most)
Or something to this effect. Sort of a “platinum card on steroids” would be my imagination as to what is viable. I think the card will either be just sub $1000 or perhaps $1250 or $1500. I doubt they go any higher with the AF than that. I’d also be surprised for there to be an initiation fee.
