It depends on if you are doing a small package (UPS) run or one of the remaining bank runs.

The bank runs operate Monday morning to Friday evening and operate out of the base. Most are multiple legs each way. They may or may not include a layover at an apartment or hotel during the day.

The small package runs are generally outstation based (meaning you live at the "out" location and spend time at a layover at the base at night.) They usually fly inbound on Monday evening and back out in the morning, finishing up on either Friday or Saturday morning.

Most new hires start in the PA31 (though some have started in the BE99 right off the bat.) How quickly you move up from that is dependant on what runs come up and how willing you are to move around to take them. If you are adamant about staying in a location it will take longer to transition to bigger equipment.
