Opened my Discover account about 80 days ago with a SL of $6,500.
Went for the CLI button and got a $500 bump to $7,000.
Just a note, I asked for a CLI maybe 2 weeks ago and was denied for "Recent cash activity" on the account. I needed $ to tip the valet on January 3rd and didn't have my debit card with me, so I took $20 out of an ATM on my Disco and immediately paid it from my phone. Apparently, they forgave it quickly.
