Pilots representing six U.S. airlines are planning an "informational" picket line Thursday at airports nationwide to demand better working conditions and benefits.

From 10:30 a.m. to 12:30 p.m., the pilots will be picketing outside Hartsfield-Jackson Atlanta International Airport, Detroit Metro Airport, and Reagan-National Airport in Washington, D.C.

Later in the day, picket lines will form outside major airports in Boston, Chicago, Las Vegas, Los Angeles, Minneapolis, New York, Orlando, Salt Lake City, and Seattle.

Travel is not expected to be disrupted as the pilots will be off duty.

The pilots say improving their work conditions is key to ameliorating the travel woes that passengers have experienced in 2022. New federal data show that in the first half of the year, on-time arrival rates dropped for nearly every major airline, while customer complaints soared.

This will be the third informational picket line this year as pilots seek to negotiate new contracts.

"When ALPA pilots stand shoulder to shoulder in support of shared goals, people notice—our airlines notice," the pilots union said in a release. "That’s why on September 1, we’re asking all ALPA pilots to join us for an ALPA-wide informational picket to show the public, our lawmakers, and our airlines that all airline pilots stand together in support of the profession-wide goal of improved working conditions and benefits."
