On a contract with Airborne starting salary, if not experienced in type, for F/O for the first 6 months is 135$ per day whether yo fly or not. Overtime I believe was somehwere around 40$ per hour above 75 hours.
If one is rated before joining the company salary is 175$ per day with increases every year. Overtime is paid at 70$ per hour above 75 hours.
Sorry for the late reply. Had to work a bit.
