WASHINGTON, March 16 (Reuters) - The Trump

administration said just over 10% of Transportation Security

Administration airport security officers on Sunday did not show

up for work as a partial government shutdown stretches to 30

days, showing no end in sight.

The standoff in Congress has forced 50,000 airport security

officers to work without pay, disrupted travel at times and

prompted CEOs of the nation's largest airlines on Sunday to call

for a quick end as spring break travel is in full swing.

Typically under 2% of TSA workers call in sick or do not

report to work, the Homeland Security Department said. At

Atlanta, New York JFK and Houston, the rates for not showing up

for work have been about 20% since February 14 when funding

expired.

DHS also said 366 TSA officers have left during the

shutdown. On Sunday and Monday, absences spiked over 50% in

Houston and over 30% in New Orleans and Atlanta and travelers

have endured two-hour or longer lines at times.

The CEOs of major U.S. airlines urged Congress on Sunday to

move quickly to end the standoff.

"Too many travelers are having to wait in extraordinarily

long - and painfully slow - lines at checkpoints," the CEOs of

American Airlines ( AAL ), United Airlines, Delta Air

Lines ( DAL ), Southwest Airlines ( LUV ), JetBlue Airways ( JBLU )

, Alaska Air ( ALK ), and others wrote.

The White House held a call on Monday with travel industry

officials including Airlines for America CEO Chris Sununu as

they push for and end to the standoff, government officials

said. The group declined to comment.

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.

Senators from both parties failed Thursday in competing

efforts ​to fund the TSA.

DHS funding lapsed on February 13 after Congress failed to

reach a deal ​on immigration enforcement reforms demanded by

Democrats.

Airlines are expecting a ​record-breaking spring ⁠travel

period, with 171 million passengers expected to fly, up 4% from

the same two-month period last year.

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.
