Republic is not a commuter friendly airline. Management has stated numerous times (on video) they want you to live in base. Outstations will be impossible to get commutable on both ends, but with seniority you will be able to hold commutable on one end.

ORD is a hub and very commutable. It’s also senior for FOs and very senior for captains (about 12 years to hold reserve, 15 years for a line). If you live on the east coast DCA or even EWR isn’t too bad. Stay away from outstations.
