Southwest to end service at Chicago O'Hare and Washington Dulles from 4 June 2026
Southwest Airlines will cease operations at Chicago O'Hare (ORD) and Washington Dulles (IAD) effective 4 June 2026, exiting two major U.S. gateways. The pullback removes Southwest's services from both airports ahead of summer scheduling, with implications for local capacity, gate allocation and competitive dynamics.
