Unite, the Union who voted overwhelmingly to reject BA's offer last Friday, have announced strike dates.
The Union which voted 81 per cent against the new offer will walk out for four days at a time unless the industrial dispute is solved.
The first of the strikes begins on 18 May, with three further strikes scheduled for 24 May, 30 May and 5 June.
Derek Simpson and Tony Woodley, Unite's Joint General Secretary said:
"BA management should take note of their own employees' strong rejection of their offer and immediately address the outstanding concerns.
"They should make no mistake that Unite is fully committed to supporting our members in furthering this dispute if no resolution is found."
