Buttigieg warns airlines to help travelers or face new rules

The Transportation Department on Friday released a copy of the letters, which it said were sent to CEOs of the major U.S. airlines, their regional affiliates, and budget carriers.

A spokeswoman for Airlines for America, a trade group whose members include American, United, Delta and Southwest, said airlines "strive to provide the highest level of customer service." She said the airlines are committed to overcoming challenges including a tight labor market.

Buttigieg's agency recently proposed rules around refunds for passengers whose flights are canceled or rescheduled. He told the CEOs the department is considering additional rules "that would further expand the rights of airline passengers who experience disruptions."

Buttigieg has been sparring with the airlines since late spring over high numbers of canceled and delayed flights. In his latest salvo, he told airline CEOs he appreciates that airlines have stepped up hiring and trimmed schedules to better match the number of flights they can handle.

"Still, the level of disruption Americans have experienced this summer is unacceptable," he wrote.

So far this year, airlines have canceled about 146,000 flights, or 2.6%, and nearly 1.3 million flights have been delayed, according to tracking service FlightAware. The rate of cancellations is up about one-third from the same period in 2019, before the pandemic, and the rate of delays is up nearly one-fourth.

Federal officials have blamed many of the disruptions on understaffing at airlines, which encouraged employees to quit after the pandemic started. The airlines have countered by blaming staffing problems at the Federal Aviation Administration, which hires air traffic controllers.
