They have us live at the destination towns served in that region, rather than at the hub. For example, for CLE ops they have us based at BFD, DUJ and PKB, rather than in CLE. This is mainly due to logistical issues with overnighting us in these small towns. IAD and ATL may prove to be the same situation. BIL is the crew base for MT ops, since it proved less difficult to have crews overnight at outstations than find permanent lodging for them.
