I was recently and pleasantly surprised with an auto CLI on my Capital One Platinum 'Credit Steps'...from $300 to $2300! I've only had the card since October 2013 and was told the maximum increase by the 7th statement would only be $200 -- for a total credit line of $500. So what a surprise!
Today I decided to request that card be pc'd to a QS.....APPROVED via online chat! The new card, cashback and no APR benefits start in 7-10 days.
If you have 'Credit Steps' use the card almost up to the max and pay it off 100% by the statement cut date. Do this every month for 4 statements and you may get an early surprise too!
Congrats! Thanks for sharing.
