British Airways cabin crew have backed a ballot for industrial action.
Unite union members voted to take action in a dispute over jobs, pay and working conditions.
The union said it would not be announcing any strike dates as it hoped to continue negotiations with the airline.
By law the union must give a week’s notice if it plans to take action – meaning strikes could begin from the first week of March.
Unite has already pledged that there will not be stoppages over the Easter period.
An earlier vote in favour of strikes was deemed illegal.
Unite general secretary Len McCluskey described the ballot result as "a clear indication of the deep sense of grievance that our members feel".
"We can only hope that BA management will now recognise the only way to resolve this is through negotiation, not through litigation and certainly not through intimidation," he said.
Cabin crew were due to take 12 days of strike action over Christmas but BA won a legal battle to prevent this, after it emerged that the union had balloted members who were no longer at the airline.
