Neither of my Barclay cards have seen any CLI action for close to a year. The last time my Rewards card received an increase was in April of '15. My Apple card received one last October. I've been calling once in awhile to see if they could reduce my APRs. I then ask if there are any promotions or SP CLIs available. That was working before but it hasn't in awhile. I tried doing that today. I figured I'd start with the Rewards card because it gets the most use and I'd like to see that one grow more. The front line representitive stopped me in my tracks. She told me the current APR is the lowest available for my account at this time. And of course there were no other promotions available. I didn't bother asking about my Apple card.
I looked into my account tonight and found that my Barclay Apple card received an auto-CLI. It would from $4400. to $7400. That's about a 68% increase. A very nice surprise! Funny thing is this card doesn't get much use but it's received more increases than my Rewards card. That one is pretty much my daily driver. I gave the Apple card some extra use over the last few weeks then bam... an increase. It might be a coincidence or the extra use helped make it happen.
