(AP) – United Airlines flight attendants have approved a new labor contract that will bring their first pay increases in six years — along with boarding pay, a long-sought change that compensates crew members for the work they do before the plane leaves the gate.

The five-year agreement, ratified on Tuesday, covers nearly 30,000 flight attendants at United. It includes an average 31% pay increase this summer, boarding pay worth an additional 7% to 8% in compensation on average and $741 million in retroactive pay, according to the Association of Flight Attendants.

“The contract will immediately change the lives of United Flight Attendants, especially our thousands of new hires who have been hired since the pandemic,” said Ken Diaz, president of the union’s United chapter. “Our solidarity delivered the goods.”

The union said the deal also secures expanded job security, restrictions on red-eye flying, pay for lengthy delays over 2 1/2 hours, higher retirement contributions, 10 weeks paid parental leave and the elimination of 24-hour on-call reserve schedules.

Both United CEO Scott Kirby and union leaders say the agreement — reached through mediation at the National Mediation Board — sets a new benchmark in the industry.

“The United Airlines Flight Attendant contract now leads the industry in total value for Flight Attendants — and it should,” said Sara Nelson, president of the AFA, which represents more than 55,000 flight attendants across 20 airlines.

In a post shared on LinkedIn, Kirby said United is “lucky to have the best flight attendants in the world to represent our airline!”

“I am very happy that they now have the industry-leading contract that they deserve,” he said.

For years, it had been standard across much of the airline industry for flight attendants to go unpaid during boarding, despite flight attendants already assisting passengers, resolving seating and carry-on issues, conducting safety checks and preparing the cabin for departure.

Delta Air Lines became the first U.S. airline to offer boarding pay in 2022, followed by American Airlines and Alaska Airlines.

Last August, Air Canada’s flight attendants put a public spotlight on the issue when about 10,000 of them walked off the job, leading the Canadian airline to cancel more than 3,100 flights. The strike ended days later with a breakthrough deal that included pay for boarding passengers.
