The Transportation Department said in a lawsuit that two of the airline’s routes were consistently delayed in violation of federal rules.
The federal government sued Southwest Airlines on Wednesday, accusing the airline of harming passengers who flew on two routes that were plagued by consistent delays in 2022.
In a lawsuit, the Transportation Department said it was seeking more than $2.1 million in civil penalties over the flights between airports in Chicago and Oakland, Calif., as well as Baltimore and Cleveland, that were chronically delayed over five months that year.
“Airlines have a legal obligation to ensure that their flight schedules provide travelers with realistic departure and arrival times,” the transportation secretary, Pete Buttigieg, said in a statement. “Today’s action sends a message to all airlines that the department is prepared to go to court in order to enforce passenger protections.”
Carriers are barred from operating unrealistic flight schedules, which the Transportation Department considers an unfair, deceptive and anticompetitive practice. A “chronically delayed” flight is defined as one that operates at least 10 times a month and is late by at least 30 minutes more than half the time.
In a statement, Southwest said it was “disappointed” that the department chose to sue over the flights that took place more than two years ago. The airline said it had operated 20 million flights since the Transportation Department enacted its policy against chronically delayed flights more than a decade ago, with no other violations.
“Any claim that these two flights represent an unrealistic schedule is simply not credible when compared with our performance over the past 15 years,” Southwest said.
