Southwest Airlines Pulls Out of Chicago O'Hare and Washington Dulles

Southwest Airlines will end service at Chicago O'Hare International Airport and Washington Dulles International Airport on June 4, 2026, marking a significant network contraction for the Dallas-based carrier.

A company spokesperson described both exits as part of Southwest's "ongoing efforts to refine its network." The airline is in the middle of a broader transformation under CEO Bob Jordan that includes assigned seating, checked bag fees, and potential additions like first-class cabins and airport lounges.

The O'Hare departure closes a chapter that began in 2021 during a pandemic-era expansion. Performance there never met expectations, and Southwest already pulled back from four O'Hare markets in 2024. The airline holds three gates at the airport, which American and United — both aggressively expanding at ORD — may absorb.

Southwest remains the dominant carrier at Chicago Midway, operating more than 90% of departures there in 2026.

The Dulles exit ends roughly 20 years of service. Southwest's presence at IAD diminished steadily after it began flying from Reagan National in 2012 following the AirTran merger. Only the Denver route remained consistent.

The Metropolitan Washington Airports Authority expressed disappointment and hope that Southwest would eventually return.

Affected passengers can rebook at no cost. O'Hare travelers may switch to Midway, Indianapolis, or Milwaukee. Dulles passengers can choose Baltimore/Washington, Reagan National, Philadelphia, or Richmond. Full refunds are also available.
