Unite has said members of British Airways’ mixed fleet crew will strike for four days at the end of next week.
The union blamed BA for the decision to strike, accusing the airline of refusing to restore travel concessions to crew members who have taken industrial action before.
Unite assistant general secretary for legal services Howard Beckett said: "It is disappointing that BA is taking such an approach when we are close to bringing this dispute to a conclusion."
BA said: "As on previous dates when Unite called strikes of mixed fleet cabin crew, we will fly all our customers to their destinations.
"Strike action is completely unnecessary. We had reached a deal on pay, which Unite’s national officers agreed was acceptable. We urge Unite to put the pay proposals to a vote of their members."
