Members of the British Airline Pilots Association (Balpa) voted by more than 9-1 to launch a campaign of action which would cause chaos to summer flights.
BA said its offer to pilots was worth 11.5% over three years, adding: “We are very disappointed that Balpa has chosen to threaten the travel plans of thousands of our customers, over the summer holidays, with possible strike action.
“Our proposed pay offer of 11.5% over three years is fair, and by contrast to Balpa the Unite and GMB trade unions, which represent nearly 90% of all British Airways colleagues, have already recommended the same pay offer to their members.
“We remain open to working with Balpa to reach an agreement, which we have been doing since December.”
Meanwhile, Unite announced that over 90 firefighters and fire and rescue staff at Heathrow have voted for strike action in a separate dispute over pay.
They will join over 4,000 Heathrow workers in strikes planned during August.
