Wow, time passes, I can’t believe it’s been 2.5 years now since this card was discontinued. With the launch of the Strata cards seemingly shelved for the time being, I feel like those of grandfathered in are just waiting to see what ends up happening with this card. (I do acknowledge Citi has a history of supporting discontinued cards for years, so it’s possible they’ll just keep servicing these for years with no changes.)
Those are the last 5x categories for any card that didn't require any sort of portal shopping (that i'm aware of). Silly of me to give it up ~5 years ago. Nothing uncapped even at 4x in my research.
