Ramp training is 7 days (not sure about CSA). It's paid at the straight time rate, with no per diem. Your hotel is paid for, but plan on sharing a room with someone. And yes, the 95% on city codes is true, even in ramp class; when I was there several years ago, a couple people were almost sent home because of it. Hope this helps. Good luck!
By the way, where in the world are we hiring?!
