Congrats for getting unsecured! Yes, I'd try for an increase online. After you fill out the info, it will tell you if they need to pull a CR. After submitting your request, if it specifically tells you that they need to pull your report, you can immediately cancel your request with no harm done, or you can continue with a hp.
Hopefully, you'll get an instant approval or two day message (no denials are allowed at Christmastime!) Good luck to you!

Mine unsecured on 10/27 and they kept denying my CLI requests, until the next statement cut then I got a $3,950 CLI
Wow! Congrats to you on a very awesome increase! You've got to feel great!
