I've been using my Chast Hyatt card a lot for the last three months, at least more than usual. They have the point bonus going on for $4,000 spend over three months, so I have hit that in about 70 days. Yesterday I logged in and see my card I've had slightly over a year moved from 5k limit to 6k.
So a $1000 CLI that I did not ask for, but they also never told me about it at all. That's surprising as I get notified from Chase about practically everything I swear, but nothing about the CLI at all. I'll take it as I never expected a CLI on a Chase card, but 1k seems pretty small. Made a single payment of over $1700 last month paying it off for the month as usual but more than double any prior payment at a single time. Assuming that the usage and payment size triggered something.
