July 3 (Reuters) - Alaska Airlines' flight

attendants are set for an average pay increase of 32% as part of

a new three-year tentative labor agreement with the airline, a

union representing the employees said.

The agreement, yet to be ratified by the Associate of Flight

Attendants union members, is also the first to make boarding pay

legally binding for unionized flight attendants, the union said

on Tuesday.

Flight attendants in the U.S. are usually paid an hourly

rate after the flight cabin doors close and it does not include

the time taken to onboard passengers.

"With boarding pay, we achieve significant pay increases,"

the union said.

Alaska Airlines did not immediately respond to a request for

comment.

The new three-year tentative contract comes at a time when

pilots and flight attendants across U.S. airlines have been

demanding better pay and benefits after the pandemic brought the

industry to a standstill and the subsequent pent-up travel

demand led to record profits for airlines.

In February, Alaska Airlines' flight attendants authorized a

strike mandate for the first time in three decades.

The tentative labor agreement, which avoids a potential

strike, includes benefits such as improvements to holiday and

overtime pay as well as 20 months of retroactive pay.

Voting for the ratification of the deal will take place

later this month, and end on Aug. 14.
