What cards do you already have and what are their CLs and UT. Also what is your AAOA and AoYA? Are those FICO scores?
Cards are as is in profile... Currently 4/24, two with 10K plus limits. AAoA shows as 9 years due to student loans. Utilization stays around 5%.
All scores in 750 range according to Fico scores.
My impression is that you would be approved.
I wouldn't worry about prequal neccessarily. I didn't have any prequal with Chase and got a CSR with 45k SL. I would definitely be looking at the CSR over the CSP. I'm not sure why anyone who could get either would get the CSP as long as they travel at all.
