This indeed should be a wake up call for the airport. WN also had gate arguements with FLL and moved a good portion of their flights to WPB. Airports have not figured out that the game is changing again, they are now a part of compition, where as before, they called most of the shots. BWI has had very good management in the past, and look how they have grown. There is a new team in place at BWI now and it will be interesting to see if they can continue to attract new flights and airlines v scaring them away like San Fran.
