I didn't see this coming. Got a letter in the mail today stating my new CL is now $10,500. Previous CL was $6800.
Card is hardly used. For all of 2018, I may have ran a total of $300 thru it.
A little history, because I know some of you will want to know. Card started out as a PLCC with a $500 limit back in 2015. Less than 6 months later it was converted to a MC with a CL of around $2k I think. Eventually getting up to $6800. No effort on my part was done to make this card grow. FICO 08 score across the big three currently range from 760 to 800.
