Here Are the 7 Routes Southwest Airlines Is Cutting From St. Louis

Southwest Airlines is reducing its footprint at St. Louis Lambert International Airport, despite the airport being one of the busiest in the country. These moves come as part of a broader network restructuring, eliminating seven nonstop routes while shifting aircraft toward stronger-performing markets. The changes, according to the airline carrier, are in an effort to reshape its domestic network to improve profitability, optimize aircraft utilization, and respond to changing passenger demand.

7 Less Routes Coming Out Of St. Louis; Southwest Airlines Says

According to recent schedule filings analyzed by aviation data providers, Southwest Airlines will discontinue seven routes coming out of St. Louis during the third quarter of 2026. While the airport remains one of the airline's largest operating bases, the latest reductions suggest that demand on these routes may be dropping, prompting the company to shift focus to higher-demand destinations in an effort to improve the company’s overall financial performance.

Southwest Airlines announced that the seven nonstop routes being removed from St. Louis include Little Rock in Arkansas, Des Moines in Iowa, Omaha in Nebraska, Tulsa in Oklahoma, Oklahoma City in Oklahoma, Wichita in Kansas, and San Francisco in California.

The cuts to these destinations include the nonstop, direct flights. So, it doesn’t mean that customers will not be able to reach these destinations through the airline. It just means that they will have to take connecting flights via other focus cities such as Dallas Love Field, Chicago Midway, Denver, Nashville, and Phoenix. The airline has emphasized that these flight route adjustments are part of its routine planning process, so they are not out of the ordinary and are actually designed to better align the airline’s travel capacity with customer demand.

Interestingly, St. Louis remains one of the airline's most important airports when it comes to customer use. Data shows that Southwest Airlines still controls roughly 61% of all seat capacity at Lambert International Airport in St. Louis, during the third quarter, offering approximately 3.2 million two-way seats. However, this number still represents an 8% decline in seating compared with the same period a year ago, suggesting that it has been hit with a decline despite its dominance.

Other Routes Hit By The Restructuring

The cuts to the St. Louis routes by Southwest Airlines come only weeks after it announced major cuts to its Florida routes. Over the past year, the Dallas-based carrier has reduced or eliminated dozens of domestic and international routes, while also exiting airports such as Chicago O'Hare and Washington Dulles. Florida, in particular, has seen significant service reductions as the airline reallocates aircraft to markets generating stronger returns.

Earlier this month, aviation website Simple Flying reported that the airline carrier is eliminating 43 routes connected to Florida between June 2026 and March 2027. This means that the cuts in St. Louis routes are only part of a much larger restructuring taking place across Southwest Airlines' network. 

According to the report, airports in Fort Lauderdale, Miami, Palm Beach, Orlando, Tampa, Fort Myers, Jacksonville, Panama City, Pensacola, Sarasota, and West Palm Beach are all affected by the reductions. Several of the discontinued routes were introduced only recently, highlighting how quickly the carrier has reassessed demand and profitability in certain markets. 

South Florida took the most hits, with Fort Lauderdale-Hollywood International Airport, Miami International Airport, and Palm Beach International Airport losing multiple nonstop connections from Southwest Airlines. Despite the route reductions, the airline remains one of Florida's largest carriers and continues to operate hundreds of daily flights across the state. 

Other US states that have also been affected by the Southwest Airlines restructuring include its complete exit from Chicago O'Hare International Airport and Washington Dulles International Airport. There have also been reductions at major hubs such as Atlanta.
