Southwest to end service at Chicago O’Hare and Washington Dulles on June 4, 2026

Southwest makes a big move

Southwest Airlines is making a notable shift in its 2026 flight schedule. The carrier will end service at Chicago O’Hare International Airport (ORD) and Washington Dulles International Airport (IAD) on June 4, 2026.

Southwest says it will continue serving the Chicago and Washington regions through Chicago Midway (MDW), Baltimore/Washington International (BWI), and Washington Reagan National (DCA).

What’s changing and when

Southwest will stop operating flights to, from, or through Chicago O’Hare (ORD) and Washington Dulles (IAD) starting June 4, 2026.

Customers traveling on or before June 3, 2026, can keep existing reservations. Customers with travel on or after June 4 can rebook through alternate airports, travel standby (where available), or request a refund for unused tickets.

The airports being dropped

The changes affect Chicago O’Hare International Airport (ORD) and Washington Dulles International Airport (IAD), two major U.S. airports that handle millions of passengers each year.

Compared with Southwest’s nearby strongholds—Chicago Midway (MDW), Baltimore/Washington International (BWI), and Washington Reagan National (DCA)—Southwest has a relatively small presence at both O’Hare and Dulles.

Why Southwest is pulling out

Southwest describes the change as part of its ongoing efforts to refine its network, and it has said operating at Chicago O’Hare “continues to be challenging.”

Reporting also notes that O’Hare and Dulles are highly competitive airports dominated by major hub carriers, while Southwest’s largest operations in the same regions are at Midway and BWI.

What passengers can do

Customers with reservations that include Chicago O’Hare (ORD) or Washington Dulles (IAD) on or after June 4, 2026, can rebook through alternate airports, travel standby in eligible cases, or request a refund for unused travel.

Southwest says affected customers traveling through O’Hare on or after June 4, 2026, are eligible for a full refund to the original payment method.

Chicago travelers have options

Passengers in Chicago can continue flying with Southwest through Chicago Midway International Airport, which remains a major hub for the airline.

Midway offers a wide range of domestic routes and is located relatively close to O’Hare. Travelers may need to adjust transportation plans, but the airport provides a reliable alternative with frequent service and strong connectivity across Southwest’s network.

Alternatives in the DC area

In the Washington region, Southwest is focusing on Baltimore/Washington International Airport and Ronald Reagan Washington National Airport.

These airports already play key roles in the airline’s network and offer strong domestic connections.

While travelers may need to travel slightly farther, both locations provide dependable alternatives with consistent flight availability and easier access to Southwest’s core routes.

A look back at O’Hare

Southwest launched service at Chicago O’Hare on February 14, 2021, expanding beyond its long-time base at Midway.

Southwest says it will end O’Hare service on June 4, 2026, and shift customers to its larger Midway operation, which it says will continue serving the same 15 O’Hare markets.

Dulles was never a core hub

Southwest has operated at Dulles for nearly two decades, but the airport was never a central hub for its operations. Instead, the airline prioritized nearby airports with stronger demand for domestic routes.

Dulles is heavily focused on international travel and dominated by larger legacy carriers. This made it less aligned with Southwest’s point-to-point model, which contributed to the eventual decision to end service there.

Broader industry challenges

Airports and airlines are facing significant operational strain due to the ongoing partial Department of Homeland Security shutdown, which has left many TSA officers working without pay and contributed to long security lines.

Airport leaders and industry groups have urged Congress to resolve the TSA funding standoff to avoid further disruption across the U.S. air-travel system.

Financial pressures behind the move

Southwest has been executing a broader business transformation to improve financial performance and reshape its network and customer experience.

In its full-year 2025 results, Southwest reported net income of $441 million and said it expects stronger financial performance in 2026 tied to its transformation initiatives.

Big changes to the airline model

Southwest has rolled out major changes to its customer experience, including a shift to assigned seating and new seat options, such as Extra Legroom, Preferred, and Standard.

The airline has also introduced new fare bundles and an updated boarding approach as part of its broader transformation strategy.

What it means for employees

Southwest says frontline employees impacted by the service changes at O’Hare and Dulles will have the opportunity to bid for open positions elsewhere in its network, including at nearby airports where it maintains larger operations.

And that’s not the only news for travelers. Global Entry is back, but airport lines are still a mess.
