Hourly rate x1000 and monthly guarantee x hourly rate x 12 are both only general estimations that will not be very accurate. As mentioned on the previous page it depends on the individual companies pay policies (cancelation pay, minimum daily guarantee, trip rig, etc.)
At Skywest I typically fly four ~23 hour 4-day trips resulting in around 92 hours credit for the month. Your results would vary based on the types of trips you bid and how much you want to work.
