Last month, Southwest Airlines ( LUV ) announced that it would stop flying to four airports in the United States and Mexico in a cost-cutting move. The Dallas-based carrier plans to end service and close operations at Bellingham International Airport, Cozumel International Airport, Houston's George Bush Intercontinental Airport, and Syracuse Hancock International Airport. Southwest ( LUV ) also plans to implement capacity reductions at both Hartsfield-Jackson Atlanta International Airport and Chicago O'Hare International Airport as part of a network optimization effort.
