Qantas has said a vote to carry out strike action by cabin crew is "a very disappointing step" as negotiations for a new agreement continue.

"They've said they'll minimise the impact to customers of any industrial action and we're urging them to stick to their word," a Qantas spokesperson said.

"The proposal we've put forward includes three per cent annual pay rises and access to more than $7000 in bonus payments.

"Cabin crew are also in line to receive 1000 shares worth around $6000."

Qantas said the shift length changes they were asking for were the same that applied to crew working at other domestic airlines in Australia.

"Crew will still have the same maximum hours over their roster period, and if they are rostered on to a longer shift they'll be compensated with overtime of up to 300 per cent," the spokesperson said.

"We want our existing crew to operate our new Airbus A321XLR when they arrive and we'll continue to negotiate towards that goal."
