British Airways pilots are to strike on 9, 10 and 27 September in a dispute over pay; the British Airline Pilots Association (Balpa) has said.
The three-day strike – the first by BA pilots – could cause severe disruption, as Balpa represents about 90% of the airline’s pilots.
The union said strikes were a “last resort” born out of “enormous frustration” with airline management.
The union said BA rejected a “number of packages” that were proposed to resolve the pay dispute, and that there remains a gap of around £5m between the two sides’ positions.
The industrial action comes after 93% of Balpa’s members voted in favour of striking.
Pilots have rejected a pay increase worth 11.5% over three years, which the airline put forward in July.
BA’s chairman and CEO, Alex Cruz, said it was a “fair deal” and called the move by Balpa “disappointing”.
He promised to provide passengers with options; either for a refund or to fly with another carrier, with the firm hoping to “minimise disruption”.
