US Air used to have 35-40 percent of the pax traffice out of BWI. Enter Southwest. Today, Southwest has 35-40 percent of the traffic out of BWI. My source is the USA Today (so it has to be true) of a few days ago. I would bet that Southwest will not go to PHL to fly around empty planes. Whatever number of flights they have, they will be full or SWA will leave town.
For those that think Southwest offers a crap product and that only the "real majors" can operate a lavish flight, I invite you to buy a ticket on Northwest Airlines. Spend a couple hundo more for the ticket, and unless the flight is over 2 hours wheels up to wheels down, first class gets what coach gets. ONE bag of pretzels and a drink of choice. Everyone on a Southwest plane has more choices and variety.
Norfwest has figured that since only 2% of first passengers actually bought a first class ticket, why give them first class service. This sounds familiar...........yes that's right, Southwest only has one class in the cabin.
Bottom line is that pax want to get somewhere and have some dough when they get there and not spend it all on the ticket. Unfortunately, the "real majors" are a little slow to figure this out.
