(CNN) -- The union representing many British Airways cabin crew members said the employees had voted to strike, though a date wasn't specified.
The union Unite said that just under 7,000 crew members voted, and that about 83% voted for strike action.
BA's cabin crew employees have been embroiled in an ongoing wage dispute over the past two years, said Len McCluskey, Unite general secretary.
"This vote shows that cabin crew remain determined to win justice. We urge BA's boardroom to see this as a clear message that they must think again about how to regain the trust and confidence of a significant part of their cabin crew operation," McCluskey said. "We continue to be in discussions with the company to find a solution to this long-running dispute."
The crew members voted on a range of anti-union management measures, including sanctions applied to some 6,700 crew who participated in a strike last year, the union said.
BA did not immediately comment on the vote.
British Airways is currently in the process of completing a merger with the Spanish airline Iberia.
