Southwest Airlines will end all service at Chicago O’Hare International Airport (ORD) and Washington Dulles International Airport (IAD) on June 4, 2026. The move is part of a broader network restructuring focused on improving profitability, with the airline consolidating operations at its established bases at Chicago Midway and Baltimore/Washington International (BWI).
Key Facts
- Effective date: June 4, 2026 — all flights to/from ORD and IAD end
- O’Hare presence: Southwest began O’Hare service in 2021, exiting after five years
- Dulles history: Service began approximately two decades ago via AirTran Airways merger
- Chicago alternative: All 15 O’Hare routes remain accessible from Midway, where Southwest handles over 90% of departures
- D.C. alternatives: Reagan National and BWI continue full Southwest service
- BWI expansion: New $520 million Concourse A/B Connector opened, handling up to 3,200 bags/hour
Why Southwest Is Leaving
Southwest Airlines entered O’Hare in 2021, making the exit a relatively short five-year presence at the airport. The carrier’s Dulles service dates back approximately two decades, initially established through the 2012 merger with AirTran Airways to balance its Washington-area operations. Both stations have underperformed relative to Southwest’s core bases, prompting the consolidation.
The restructuring aligns with Southwest’s ongoing profitability overhaul, which has included route optimization, fleet adjustments, and a shift toward higher-yield markets. The airline is directing resources toward airports where it holds a dominant market position.
Impact on Passengers
Affected passengers with bookings on or after June 4 involving O’Hare or Dulles have two options. First, they can rebook or fly standby to nearby alternate airports within 14 days of their original travel date at no change in fare. Chicago-area alternatives include Midway, Milwaukee Mitchell, and Indianapolis International. Washington-area alternatives include Reagan National, BWI, Philadelphia International, and Richmond International. Second, passengers can request a full refund for unused tickets, including nonrefundable fares, plus any optional fees for canceled segments.
Midway and BWI Consolidation
Southwest will continue to operate its full Chicago network from Midway International Airport, where it is projected to handle more than 90% of departures. The airline confirmed that all 15 markets currently served from O’Hare will remain accessible from Midway.
In the Washington, D.C., area, BWI has emerged as Southwest’s primary East Coast hub. The airport recently opened a $520 million Concourse A/B Connector featuring 142,000 square feet of new construction, five upgraded gates, and an advanced baggage handling system capable of processing up to 3,200 bags per hour. Southwest has also added new routes from BWI in 2026, including service to St. Thomas, Knoxville, St. Maarten, Oklahoma City, and Pensacola.
