Southwest Airlines Ends Flights at Chicago O’Hare in June 2026

This article summarizes reporting by CBS News Chicago and Sara Tenenbaum.

Southwest Airlines is officially ending its five-year operational stint at Chicago O’Hare International Airport (ORD). According to reporting by CBS News Chicago, the Dallas-based carrier announced on Friday, March 13, 2026, that it will cease all flights at the major international hub this coming June.

“Southwest Airlines announced Friday that it will stop operating flights out of Chicago O’Hare International Airport in June,” reported Sara Tenenbaum for CBS News Chicago.

The strategic retreat also includes a simultaneous withdrawal from Washington Dulles International Airport (IAD). The final day of service for both airports will be June 3, 2026, marking a significant network optimization effort by the airline. For travelers, this signals a definitive shift back to Southwest’s traditional stronghold at Chicago Midway International Airport (MDW), where the airline plans to consolidate its Chicago-area operations and absorb displaced routes.

Timeline and Customer Accommodations

Managing the June Transition

The operational cutoff is set for early June. As detailed in official Southwest Airlines travel advisories and highlighted in the CBS News Chicago report, the airline’s final flights out of O’Hare will depart on June 3, 2026. Any itineraries scheduled for June 4 or later will be directly impacted by the closure, while travelers flying on or before June 3 will experience no disruptions.

To mitigate inconveniences, Southwest is offering flexible accommodations for affected passengers. Travelers holding tickets for June 4 and beyond are eligible for full refunds on unused fares. Alternatively, passengers can rebook or fly standby from nearby alternative airports, including Chicago Midway, Milwaukee Mitchell International Airport (MKE), or Indianapolis International Airport (IND).

The Return to Midway

Consolidating Chicago Operations

Southwest’s departure from O’Hare represents a return to its historical strategy. For decades, the airline famously avoided the congestion of O’Hare, choosing instead to dominate the smaller, more manageable Midway Airport. This strategy worked flawlessly for the airline prior to 2021, allowing for rapid turnarounds and high aircraft utilization rates. The carrier only expanded into O’Hare in 2021 during the pandemic to capture shifting market share, making this June exit the end of a five-year experiment.

Now, the airline is doubling down on its South Side hub. Industry research reports indicate that Southwest will increase its capacity at Midway to compensate for the O’Hare exit. The airline plans to operate up to 244 daily departures from Midway, serving more than 80 nonstop destinations. Furthermore, 15 markets previously served from O’Hare will be transferred to Midway, ensuring that Chicago travelers retain access to these routes without losing overall network connectivity.

Broader Industry Challenges

Boeing Delays and Network Optimization

The decision to exit O’Hare and Dulles does not exist in a vacuum. The broader aviation industry is currently navigating a complex web of operational hurdles, including FAA congestion caps, air traffic controller shortages, and severe aircraft delivery constraints. Airlines are increasingly forced to make tough choices about where to deploy their limited resources, often retreating to core hubs where they maintain dominant market share.

Southwest has been forced to make difficult network decisions over the past few years. In April 2024, the airline announced significant capacity reductions at O’Hare and Hartsfield-Jackson Atlanta International Airport, while completely exiting four other markets, including Houston’s George Bush Intercontinental and Syracuse.

During the company’s Q1 2024 earnings call, CEO Bob Jordan attributed those earlier cutbacks to financial underperformance and ongoing delivery delays from Boeing. The 2026 withdrawal from O’Hare appears to be a continuation of this long-term strategy to optimize resources amid constrained fleet growth.

AirPro News analysis

We view Southwest’s exit from O’Hare as a pragmatic admission that the 2021 pandemic-era expansion into ultra-congested legacy hubs has yielded diminishing returns in today’s constrained operating environment. By retreating to Midway, Southwest reclaims its operational reliability and shields itself from the severe air traffic control and congestion issues that frequently impact O’Hare. While the loss of competition at O’Hare may marginally impact fares at that specific airport, Southwest’s aggressive capacity transfer to Midway ensures the broader Chicago market remains highly competitive.
