Do you mean it's not a hub for city pairs like DL flying there from ATL? Those DL pilots could be based in LAX, DFW, CVG, NYC, ATL, or any other crew cities I'm forgetting. They might fly to BWI and turn around and go back to ATL, and finish up the day in JAX...just a make believe day. Or, they might stay overnight in BWI and fly to ATL or another DL hub the next morning. Only at the end of the trip do they have to return to the flight crew base (although there's a good chance that they'd stop in sometime during the trip anyway).
