British Airways workers based at Heathrow have voted to strike in a dispute over pay.
Members of the GMB and Unite backed industrial action, with the unions saying holidaymakers face disruption, and warning of a summer of strikes. Workers, including check-in staff, will now decide on strike dates, which the union said were likely to be held during the peak summer holiday period.
Nadine Houghton, GMB national officer, said: "With grim predictability, holidaymakers face massive disruption thanks to the pig-headedness of British Airways. BA have tried to offer our members crumbs from the table in the form of a 10% one-off bonus payment, but this doesn't cut the mustard.
