SFOIntern, it seems to me that Southwest will likely ramp up at BWI when MetroJet shuts down. On some routes Metrojet competes heavily with WN--six daily flights, for instance, on BWI-PVD. MetroJet has been packed every time I've flown it or seen their BWI departure lounge this year. They're carrying pax (tho probably fewer right now). MJ's cost structure doesn't allow it to make money at WN fares. It seems to me Southwest could easily add three or four flights on BWI-PVD (factoring in post 9/11 traffic drop) and make money.
Multiply that to three quarters of MJ's 55 daily flights at BWI, and you'd see a 20 percent ramp up (approx 150 daily WN departures to approx 190). My own eyeball assessment of BWI suggests that WN could put 20 percent more flights through its 21 gates. It'd be a bit of a squeeze, but it could be done.
Figure that US will pull the 1992 a**hole maneuver again and sit on empty gates at BWI....let them. The new concourse A expansion will be done in 2002 (things are *really* moving at BWI, has anyone seen it recently?). Southwest will have room.
Now they just need to backfill ROC, SYR, and other medium-haul markets at which they'd make a killing from BWI.
