Got my amtrak card last summer, had a really low limit of 2k. Then was able to get a SP increase to 4k. and 3 or 4% apr reduction. Did one small BT. Then about 5 months ago, paid off BT, I asked for 15, and it gave me the full amount. Using it heavily since. So today, thinking that there was no chance that they would approve the full 25k, and give me the 20k I desired, nope, full 25k approved. So yeah, I probably left some money on the table, and I am totally ok with that. I may try again in the next 2 weeks to use the same inquiry and go for more, but I am pleased. If it ends up not working out a 2nd time, I am not even going to call in and ask because this is adequate as is and dont want to look greedy. And it wasn't until just a few weeks ago that my amex cli had reported (from 15k to 24k) and then recently the request link showed up on boa. This is really one of my favorite cards since I use amtrak so much, and especially where my Amex SPG isnt accepted, its almost 3 cents a point in value.
This forum has been so helpful. To think 2 years ago all I had was a $500 limit credit one, 6k limit care credit, and a 500 limit buckle card. I think this CLI will come in handy later this year to leverage a BBR approval hopefully.
Also with all of these horrific storms and damages, I may just use 20-25% of the limit for some repairs not covered by insurance. I would love to run the repairs through this card, then debt shuffle them to my capital one as it has no BT fee, then BT it back to this card to wash out the 3% bt fee, but I am not going to do that. 0% until feb 2018.
I am excited to see what happens with my double cash next month when I try a SP cli. And see if I can get another APR reduction on this Amtrak card.
