I didn't want to de-rail the GTC discussion, but if you have the Chase sapphire reserve I would suggest getting the Hilton Aspire card, there are some great benefits to it. $250 dollars for airline fees but I have gotten gift cards with American Airlines with no issues. $250 dollar resort credit at Hilton resorts. A free hotel stay once a year. And probably the best perk is automatic Diamond status with Hilton.
Chase waives the annual fee for AD. I am not sure if we can share referral codes but I would happily share mine via PM to get 20K hilton points.
