Southwest Airlines has established a dominant presence in several U.S. airports, distinguishing itself from the traditional legacy carriers like United Airlines, American Airlines, and Delta Air Lines. While these three airlines dominate air travel in most U.S. cities, Southwest has carved out significant market shares in select locations.
At Pittsburgh International Airport (PIT), Southwest holds the strongest position since legacy airlines' departure. The airline capitalized on the void left by US Airways after its collapse and removal of its hub at Pittsburgh in 2004. "The carrier has maintained the strongest position in this market since the departure of legacy airlines," with a current market share of 26.11%, surpassing its nearest competitor.
Dallas Love Field (DAL) serves as a major operating base for Southwest, which commands over 96% of flights there. The repeal of the Wright Amendment allowed Southwest to expand its operations significantly at DAL. "Southwest's presence at this airport demonstrates an interesting phenomenon," showing how legislative changes can impact airline dominance.
