The U.S. Department of Transportation is investigating the Southwest Airlines holiday travel debacle, which left thousands of travelers stranded for days. The investigation comes as the airline reported a $220 million loss last quarter and further losses in the first quarter.
Southwest canceled more than 16,700 flights over several days in late December. While a massive winter storm caused the initial cancellations, the company’s outdated software systems turned what should have been a normal problem into a snowballing disaster that lasted for days after other airlines had resumed their usual operations.
The department’s investigation will look into whether Southwest made unrealistic flight schedules, “which under federal law is considered an unfair and deceptive practice,” according to a department spokesperson.
“DOT has made clear to Southwest that it must provide timely refunds and reimbursements and will hold Southwest accountable if it fails to do so,” the department spokesperson said.
The flight cancellations cost the company about $800 million, according to Bob Jordan, the airline’s president and chief executive officer.
