Southwest Airlines will end service from both Chicago O'Hare (ORD) and Washington Dulles (IAD), removing dozens of daily flights from two airports where United Airlines operates major hubs. While Southwest's presence at each airport was relatively small, the timing of its exit could provide an unexpected boost for United, especially in Chicago.

Why it matters

Southwest's departure from these two major airports will give United Airlines, which operates large hubs at both locations, a competitive advantage as it seeks to grow its market share. This move could allow United to capture more passengers and increase its dominance in these key travel markets.

The details

Southwest Airlines will soon end its short-lived experiment at Chicago O'Hare International Airport, leaving the airport once again dominated by its two traditional hub carriers: United Airlines and American Airlines. The airline is also pulling out of Washington Dulles, further consolidating United's presence at that airport.
