First to report: Southwest post 4Q profit

Catching up to yesterday's first fourth-quarter earnings report, here's the story of  how Southwest made money in the last three monhs and for the year. From this story, you can also link to a news brief about Southwest's plans to drop service to Allentown's Lehigh Valley International Airport and to Harrisburg as it restructures what had been the AirTran route network. Apparently those two cities don't fit into the new Southwest business model.
