In the past I've not had much luck with BoA (today that would be US Bank and Citi-branded cards) but last summer I gave them another shot which resulted in the red Cash Rewards Visa with a SL of $2k .... I though here we go again with BoA and their toy limits. In January this year the request a CLI showed up so I punched it and asked for $10k - instantly approved...now its a reasonable limit. In February I said okay lets push our luck with BoA and go for the blue Travel Rewards cand, instant approval $18k SL,,, yes a bit surprised, but now we are getting somewhere. Yesterday the request a CLI on the Cash Rewards card showed up again, so of course I punched it and asked for $15k, instant approval new CL $15k. The CLI request is still showing on my accounts, but I'm not going to get greedy as most of my cards are in the $15 to 20k range, I'm good and I think I might just become a BoA fan after all. 
Pipe meet Boa meet Guy meet Cli meet $$$$$$
Just keep going about it like you been with them in the same exact way.
They will grow and grow and keep growing like Jack and The Beanstalk.
BofA Really Rocks!
