The bitter dispute involving thousands of British Airways cabin crew will take another twist later when union leaders will hear whether they can go ahead with a series of planned strikes.
A wave of five-day walkouts was due to start this week but BA was granted an injunction against the Unite union, granting a reprieve to the airline's passengers.
The union lodged an appeal, with the decision due to be announced this morning.
If the judgment goes against Unite, the union is expected to hold another ballot of thousands of cabin crew in the long-running row over pay, jobs and working conditions.
But if the judges accept Unite's appeal, the strikes will go ahead, probably starting next Monday.
Unite originally announced four five-day stoppages from May 18-22 inclusive, then from May 24-28, May 30-June 3 and June 5-9, the last strike ending just days before the start of the football World Cup in South Africa.
