Right on the 6 month cycle, Citi approved the following increases:
Costco: 8,500 to 12,500 (Started at 7K Oct 2017. 1500 SP CLI at 6 months)
Double Cash: 21,500 to 23,000 (Started at 7.9K March 2017. HP CLI to 20K Oct 2017)
FICO score: 740 as of 9/25/18 per the score they provide.
I was only expecting $1500 on both so the Costco was a great surprise. I've been using it more and more. 4% Gas, 3% Restaurants and Travel is awesome. Double Cash I only use for concert tickets that require a Citi card for pre-sales. Most of my spend goes on Discover or Chase Freedom for the 5% categories.
It's been SP increases like these that have helped me to not go stir crazy while I wait for my accounts to age.
