Southwest Airline provides low-fare air transportation service among 64 airports in 34 states in the USA (2009). Although the airline industry suffered a major blow from the terrorist attack of September 11th, 2001 and the 2008/2009 economic crisis, the company is still holding strong; while other airline companies are in debt or have gone bankrupt. The major success th their continued success seems due to their low-cost model and competitors being aware that they cannot match Southwest Airline' low prices. Southwest Airlines has the reputation of being able to force a competitor into bankruptcy.
