How long must you waite to call in ask Discover for credit line increase. My last increase was about 6 weeks when I got an increase of 1500 to cl of 27K.
There is no set time frame. Most people wait 30-60 days between requests. There have been reports of CLI as close together as 21 days, though, so anything is possible. You can also do your requests online in a matter of 20-30 seconds rather than having to call in.
My 3rd statement cuts July 2nd... curious as to whether I get an auto CLI
Mine is cutting around the same time. Hopefully there will be some CLI for us.
