Southwest Airlines will pull out of Chicago O’Hare International Airport (ORD) and Washington Dulles International Airport (IAD) entirely on June 4, 2026. The announcement came March 13, 2026, and covers all flights scheduled to operate from either airport on or after that date — a firm end to what the carrier itself acknowledges has been a years-long struggle to make both high-cost, slot-constrained airports work inside its low-fare model.
The Exit — What’s Confirmed
Southwest launched O’Hare service on Valentine’s Day 2021, betting it could carve out a viable presence alongside the American and United hubs that dominate the airport. It never really took. By 2024, the carrier had already slashed O’Hare frequencies and exited Houston Intercontinental (IAH) — a structurally similar situation, with a dominant Southwest base across town at Hobby. That IAH parallel runs deeper than it might appear: Southwest first tried and abandoned IAH as far back as 1992, just one year after beginning operations there. O’Hare is now repeating that pattern.
The June 4 withdrawal eliminates more than 300 flights from ORD and vacates Southwest’s three gates there. Those gates are widely expected to be absorbed by American or United under the airport’s use-it-or-lose-it gate allocation policy.
Dulles tells a parallel story. Southwest has operated at IAD since October 2006, but the operation stagnated after the 2012 AirTran merger handed the airline initial access to Reagan National (DCA) — a far more convenient airport for most D.C.-area travelers — and was further marginalized when the American/US Airways merger in 2014/2015 produced a significant slot divestiture that greatly expanded Southwest’s DCA presence. Denver was the one consistent route Southwest maintained at Dulles throughout that period; Phoenix was added later. By early 2026, the entire Dulles network had contracted to just those two routes. The Metropolitan Washington Airports Authority, which operates IAD, said it was “disappointed” by the decision and expressed hope Southwest would return someday.
Consolidation at Midway and BWI
Southwest isn’t abandoning Chicago or Washington. It’s retreating to stronger ground.
At Midway (MDW) — where Southwest has operated for 41 years since 1985 — the airline will offer up to 244 daily departures serving more than 80 nonstop destinations. Every one of the 15 markets currently served from O’Hare will remain accessible from Midway, meaning passengers lose a departure airport, not a destination. Cirium schedule data shows Southwest operating more than 90% of MDW’s departures in 2026, cementing its grip on the airport.
In the Washington region, Southwest remains the second-largest carrier by seats at Reagan National after American and maintains its large BWI operation. Affected Dulles passengers can rebook to DCA, BWI, Philadelphia, or Richmond without paying a fare difference.
Where the Aircraft Are Going
The aircraft freed from ORD and IAD aren’t being parked — they’re funding a 31-route expansion. Most notably, Southwest launches inaugural service to Anchorage’s Ted Stevens International Airport on May 15, 2026, with daily nonstop flights from both Denver and Las Vegas. New international leisure routes include Orlando to St. Maarten and Las Vegas to San Jose, Costa Rica.
Adam Decaire, Southwest’s SVP of network planning, framed the redeployment plainly:
“We are continuing to add more Southwest service for our customers in the places where we’re already strong. We will meet our customers where they are with an enhanced product that complements our best-in-class reliability and service.”
The Bigger Picture — Southwest 2.0
These exits don’t happen in isolation. Southwest is mid-transformation. Assigned seating launched in 2026, with numbered boarding groups — 1 through 8 — replacing the open free-for-all on January 27, 2026 as part of that same initiative, and new fare buckets (Basic, Choice, Choice Preferred, and Choice Extra) restructure the ticket-buying experience. CEO Bob Jordan has also floated first-class cabins, airport lounges, and intercontinental flying as longer-term possibilities.
The carrier posted a net income of $441 million for full-year 2025 and is projecting stronger returns in 2026 as the transformation matures.
The O’Hare withdrawal also lands at a politically charged moment for the airport. With more than 3,000 flights per day scheduled this summer, the FAA and DOT have already ordered ORD to reduce its schedule amid chronic congestion — the Chicago Department of Aviation arguing the airport can handle 2,800 daily operations while the FAA pushes for a cap of 2,400. Losing Southwest’s three gates and 300-plus flights gives the legacy carriers more room to maneuver, though analysts note it could reduce price competition on certain O’Hare routes.
Flights scheduled on or before June 3 operate as planned.
