Here's the deal. 10k, 12mo training contract for FOs non-prorated. $18hr with a 60hr monthly guarantee. If/when you upgrade it's another 10k, 12mo non-prorated. Per diem only on overnights at $1.25. FO training is done in house but captain initial is done at Flight Safety in Wichita. Oh when you head out there you pay all of your expenses for lodging and food is out of your own pocket and upon successful completion of training, you may file an expensive form for at least the lodging.
I still have friends there so I won't tell any stories about what happens in flight ops but when I had my exit interview, I was shown a piece of paper that had a bunch of numbers on it. This was all of my paychecks from my time there and how much from each paycheck I was undercharged for insurance or something. They ended up garnishing my final paycheck for money I didn't know I owed them. That's the ACO experience right there.
