WASHINGTON, D.C.— Southwest Airlines (WN) has announced plans to discontinue operations at two major U.S. airports as part of its broader network restructuring strategy. The airline will end flights to Chicago O’Hare International Airport (ORD) and Washington Dulles International Airport (IAD) starting June 4, reducing its footprint in two of the country’s busiest aviation markets.
The decision reflects the carrier’s ongoing effort to refine its network and improve profitability while strengthening operations at other airports. Despite the exit from ORD and IAD, Southwest will continue to serve the Chicago and Washington metropolitan areas through Chicago Midway International Airport (MDW), Baltimore/Washington International Thurgood Marshall Airport (BWI), and Ronald Reagan Washington National Airport (DCA).
Southwest Exit Plan from 2 Airports
Southwest confirmed that flights to both Chicago O’Hare and Washington Dulles will end on June 4. The airline described the change as part of its long-term network optimization strategy aimed at improving route performance and operational efficiency.
The decision comes during a period of major transformation for the Dallas-based carrier. Southwest has been exploring new revenue strategies, including seat assignments, baggage fee adjustments, and other initiatives designed to strengthen financial performance.
Company leadership has also signaled broader future changes. Potential developments could include premium seating options, dedicated airport lounges, and even long-haul international flights beyond the airline’s current network.
Southwest’s Chicago Strategy Shift
Southwest began flying to Chicago O’Hare in 2021 during a large network expansion that took place at the height of the pandemic. The airline launched service to multiple new airports across the United States as travel demand patterns changed.
However, the operation at O’Hare never expanded as expected. Several routes from the airport were already reduced in 2024 after the airline determined that some markets did not meet its financial targets, reported The Points Guy.
Competition at O’Hare has also intensified. American Airlines and United Airlines have been rapidly adding flights in order to maintain valuable gate space under the airport’s use-it-or-lose-it policy.
This aggressive expansion has created operational pressure at the airport. Federal regulators have even implemented temporary limits on flights during peak periods to reduce congestion and improve air traffic flow.
Southwest’s exit from O’Hare will likely free up its gates for other airlines operating there. At the same time, the carrier maintains a dominant presence at Chicago Midway, where it is expected to operate more than 90 percent of departures in 2026.
Dulles Operations End for WN
Southwest’s departure from Washington Dulles marks the end of more than two decades of service at the airport. The airline originally launched flights there to expand its presence in the Washington region.
Over time, however, the airline concentrated most of its regional operations at Baltimore/Washington International Airport. The airport remains one of Southwest’s largest bases in the United States.
Following its merger with AirTran Airways in 2012, Southwest also gained access to Ronald Reagan Washington National Airport. That move strengthened the airline’s presence closer to downtown Washington and reduced the importance of Dulles in its network.
In recent years, the Dulles schedule remained limited. Only a small number of routes operated consistently, with Denver International Airport serving as the primary destination.
Passengers affected by the closure will receive flexible options. Travelers booked on flights after June 4 can rebook to nearby airports or request full refunds, according to the airline.
