I would guess if you joined recently you should see one in the mail.
I joined recently but I probably won't get the invite if it's a Chase card. When I got the Continental, a Chase person called and was all "WTF are you trying to do with all these cards?". Once I get the extra 25K on Continental and confirm there's no need for a Houston trip in April, I'll cancel that one and should have better luck getting a United deal. Really trying to get this lined up so I end up with 100K+ United miles after the merger.
How many Chase cards did you get until the "WTF" call? I might be getting close to this
I'd already had a non-travel miles card and my car payment (I buy brand-new cars I want and finance what I don't pay with my down payment). Got Marriott first, no problem. Got Priority Club and they called to say they were going to shift credit limits between cards, told them I didn't care. Got Hyatt, no problem. Applied for Continental, was taking a while, they came out with the $50 statement credit in the meantime, applied again, they called asking if I wanted 2 continental cards and also stating my credit limit wouldn't be much on it as I had 5 other chase accounts, told them I just wanted one and I didn't care what the limit was and in fact $1000 was fine as that's more than enough to get a plane ticket.
Will probably cancel out Continental and Hyatt by summer. Then get United.
