![Massive Cuts: Southwest Airlines Ends 7 Routes From This Important Airport [List & Map]](https://www.mogazmasr.com/uploads/2026/06/29/southwest-airlines-st-louis-cuts-c37ffdc3_800w.webp)
Southwest Airlines will cut seven routes from St. Louis Lambert International Airport in the third quarter of 2026, trimming service that it flew in the same period a year earlier. The moves remove short-haul flights to Des Moines, Little Rock, Tulsa, Wichita and Oklahoma City, along with service to Long Beach and San Jose.
The cuts matter now because Southwest still has 9,945 scheduled departures from St. Louis in Q3 2026, leaving the airport as the carrier’s 11th-busiest base even after the reductions. Domestic flying accounts for 9,819 of those departures, or 98.73%, while the seven dropped routes together would have offered 1,608,629 one-way seats.
Five of the seven routes are the kind of shorter Midwest flights that once added up to only 107 departures from St. Louis last year, and Oklahoma City had 108. Long Beach had 34 flights and San Jose had five, making the two California routes small pieces of the network even before the latest schedule change. Southwest is also keeping 126 flights to foreign airports from St. Louis, with Cancun accounting for 112 of those rotations and Montego Bay, Punta Cana and San Jose del Cabo continuing to appear in the schedule.
That is why the airline’s message cuts against the math. Southwest says it is fully committed to the Gateway City and looks forward to serving the market for years to come, even as it pulls back from seven city pairs and looks to focus more of its capacity through Nashville International Airport. The shift away from point-to-point flying is part of the same strategy, and it helps explain why the carrier can be expanding in one place while taking away direct service in another.
St. Louis has long been a key base for Southwest, and Cirium’s records show how sharply the airline has built and reset the operation over time, from 20,641 flights in 2004 to 40,450 flights and 6,109,086 seats in 2019. The latest reduction does not erase that history, but it does show a carrier narrowing its network even at an airport where it still moves a large volume of passengers. What Southwest decides next for St. Louis, and how much more capacity it shifts toward Nashville, is the question now hanging over the schedule.
