The southwest airlines louis cuts remove nonstops to Des Moines, Little Rock, Tulsa, Wichita, Oklahoma City, Long Beach, and San Jose as the carrier reallocates capacity toward Nashville and connecting traffic.
Key Takeaways
- Seven STL routes that operated in Q3 2025 will not run in Q3 2026, per Cirium schedule comparisons cited by Simple Flying.
- Five Midwest markets each had about 107 to 108 departures last summer; California links to Long Beach and San Jose had far fewer flights.
- St. Louis remains Southwest's 11th-busiest base with 9,945 planned Q3 departures and more than 1.6 million one-way seats.

Why Is Southwest Cutting Routes From St. Louis?
Simple Flying reports that Southwest is focusing more capacity through Nashville International Airport while moving away from its historic point-to-point model. Nomad Lawyer describes the St. Louis pullback as part of a portfolio optimization strategy driven by fuel costs, operational efficiency, and shifting passenger demand.
The Suncoast Post notes similar patterns elsewhere in Southwest's network, including trimming thinner seasonal routes and concentrating flying through stronger connecting markets. Chicago O'Hare service ended in June 2026 as the airline consolidated Chicago operations at Midway.
Which Seven Routes Are Being Dropped?
According to Cirium data cited by Simple Flying, the eliminated St. Louis routes are Des Moines, Little Rock, Tulsa, Wichita, Oklahoma City, Long Beach, and San Jose. Four Midwest destinations each logged 107 departures from STL in Q3 2025, with seat totals between 15,845 and 17,829. Oklahoma City had 108 flights.
Long Beach saw 34 departures and San Jose just five during the same period last year. Nomad Lawyer confirms seven regional routes will end in Q3 2026 but does not independently list each city pair.
How Large Is Southwest's Remaining St. Louis Operation?
Despite the cuts, St. Louis stays a major Southwest base. Cirium figures show 9,945 scheduled Q3 departures in 2026, ranking STL as the airline's 11th-busiest airport. Those flights will offer roughly 1,608,629 one-way seats.
Domestic service accounts for 98.73 percent of departures. Top remaining destinations include Denver (610 flights), Orlando (545), Dallas Love Field (512), Chicago Midway (458), and Las Vegas (433). Only 126 international rotations are planned, led by Cancun.
What Should St. Louis Travelers Do Now?
Passengers who relied on the discontinued nonstops may need connecting flights through Denver, Nashville, Chicago Midway, or other Southwest hubs. Nomad Lawyer advises checking directly with the airline for rebooking options, since transition policies vary by ticket.
The airline's stated commitment to St. Louis suggests the hub is not being abandoned, but the route map is tightening. For more on how data-driven networks are reshaping travel, see our Future Tech & AI Wonders coverage.
