I think OP is interested in highest "initial" CL's. Most prime cards will grow over time if you are prudent in their use and payment. But some CCC's have a better record for higher than average initial CL's.
The CL's I listed were my highest "initial" or opening CL's.
I just applied for the Chase Southwest Airlines card. I've flown them a bit for work and was booking more personal flights...
I got an instant approval for $2000.00, however, about 5 days later, I got an email congratulating my approval and... it noted a $20,500.00 credit line!!!! No kidding! At first, I thought it was some sort of typo, but the card just came in the mail and it's definitely at 20k+.
One thing too keep in mind - they do charge an annual fee (of $59.00), which I am really against, but I overlooked that because they give me two flight credits (you need 16 for a free round-trip ticket) each anniversary.
That's a nice limit, stonewell! Congrats, and welcome to the forums!
I''ve considered app'ing for this card. I like Southwest as an airline, and could use the free flights (to Vegas, of course!), but I'm not a big fan of Chase these days. That's the only thing holding me back.
