Southwest Airlines exits multiple airports as Boeing troubles weigh

Southwest Airlines announced Thursday that the carrier is pulling out of several airports as it contends with financial fallout from Boeing delays. 

CEO Bob Jordan warned in Southwest's latest earnings report that the carrier has intensified its network optimization efforts to address underperforming markets. 

As a result of these efforts, the Texas-based carrier is closing operations at Houston's George Bush Intercontinental Airport in Houston, the Bellingham International Airport in Washington, the Cozumel International Airport in Mexico and the Syracuse Hancock International Airport in New York.
