British Airways (BA) cabin crew are ready for further strike action, union Unite has announced.
The union balloted 10,220 of its BA crew members on whether they would be prepared to stage a walk-out.
A majority of more than 78%, from a high turn-out of 75%.
Len McCluskey, unite's general secretary-designate, said the turn-out for the latest ballot had been larger than for the previous vote.
“For the fourth time in 13 months, British Airways cabin crew have voted overwhelmingly in support of their union and expressed their dissatisfaction with management behaviour," he said.
"Surely BA management must now wake up and listen to the voice of their skilled and dedicated employees."
McCluskey called for BA to start conciliations.
"This dispute will be resolved by negotiation, not litigation or confrontation, and it is to negotiation that BA management should now apply itself. We are ready."
