The CEOs of major US airlines urged Congress on Sunday to move quickly to end a 29-day partial government shutdown that has forced 50,000 airport security officers to work without pay, warning it could further disrupt US air travel.

Absences by Transportation Security Administration (TSA) officers had already disrupted travel at some major airports over the previous week, raising alarm as the busy spring break travel season continues.

“Too many travelers are having to wait in extraordinarily long – and painfully slow – lines at checkpoints,” wrote the CEOs of American Airlines, United Airlines, Delta Air Lines, Southwest Airlines, JetBlue Airways, Alaska Airlines and others in an open letter to Congress.

They added: “First, leaders should immediately come together to reach an agreement to fund the Department of Homeland Security. Then they need to act so this problem never happens again.”

Last fall, a 43-day government shutdown led to widespread flight disruptions and the FAA ordered a 10% flight cut at major airports. “Once again air travel is the political football amid another government shutdown,” the CEOs wrote.

The group of airline executives – which also includes senior executives at cargo carriers FedEx, United Parcel Service, and Atlas Air – called for legislation to ensure during future government shutdowns all critical government aviation personnel are paid.

Senators from both parties failed on Thursday in competing efforts to fund the TSA, which said last week that more than 300 officers have quit since the shutdown began.

The homeland security department’s funding lapsed on 13 February after Congress failed to reach a deal on immigration enforcement reforms demanded by Democrats. They made those calls after federal immigration agents fatally shot two 37-year-old US citizens in January, Renee Good and Alex Pretti.

Airlines are expecting a record-breaking spring travel period, with 171 million passengers expected to fly, up 4% from the same two-month period in 2025.

Earlier in March, some airports such as Houston Hobby and New Orleans reported security lines exceeding two hours as TSA absences rose. The Newark airport on Saturday said it was experiencing more delays than normal.

“Americans – who live in your districts and home states – are tired of long lines at airports, travel delays and flight cancellations caused by shutdown after shutdown,” the CEOs wrote.

Some airports have closed some security checkpoints, and others are working to raise money to help TSA workers buy food or other essentials as they go without pay.
