Just to specify about the pay.
AMF doesn't pay per diem, a regional does.
At AMF I was making less than 1900$ A month after taxes and before Heath insurance and 401K. In a regional, because of the per diem, I'm making more than 2300-2400$ a month.
After one year at AMF the pay raise is about one dollar per hour, basically you maintain the same low pay. In a regional you go from an average of 22$ an hour to an average of 30-35$ an hour, so the pay raise is significant. Of course regionals are different and you won't be rich in any case but I should do my research.
You are absolutely right the the companies are playing at paying the pilots lower and lower, that's what AMF does and if you go for it your are doing exactly that. In the regional world because of that 10k pilots have just voted down the new contract because they want to be paid and treated better and that's the only time in the aviation industry when the management needs pilot.
Said that, if AMF offers a turbine PIC position in a part 135 company they should also pay a turbine PIC salary. In this very website you'll find that a part 135 capt makes an average of 50-90K in a part 135 corporate, at AMF you'll make 25K.
They give you a PIC job but they'll pay you less than a SIC.
You can find this numbers on this very same website!
As I sad, recruiters will tell you whatever you want to hear but I have my pay checks in my hands and they don't lie.
Finally, what's the point to fly as a PIC at AMF to go for a SIC job after that?
