The U.S. Department of Transportation has waived the final $11 million of a $35 million civil penalty against Southwest Airlines for massive flight cancellations during a 2022 winter storm.

The airline had canceled 17,000 flights, stranding over 2 million passengers, and was initially fined for failing to assist travelers.

Southwest had already made $24 million in payments, and the waiver reflects the company’s significant improvements in on-time performance and investments in network operations.

The DOT said the move benefits the public by encouraging airlines to enhance operational resilience rather than simply paying fines, NBC News has reported.

Southwest praised the decision, highlighting its successful operational turnaround and improved customer service.
