So regionals do the 5am departures out of the smaller cities to get people into the hubs and do the late departures out of hubs back to the smaller cities, called outstations.

Republic and a lot of other regionals like to cut costs, so they set up outstation bases at these smaller airports where crew rooms and maintenance hangars are cheaper. If you're willing to move, these can be nice for FO's because the cost of living is typically cheaper. However, if you commute there is a good probability you'll have to go in the night before or leave the day after your trips due to the early starts and late finishes. Also, if you don't live in a hub, you're probably looking at a 2 leg commute through a hub.
