There will be a pause in industrial action among British Airways' mixed-fleet cabin crew in a bid to resolve a conflict over pay and penalties for striking workers, Britain's Unite Union said on Tuesday.

Unite members who work for the mixed-fleet, which serve short and long haul routes, have been on strike since the beginning of July, and the industrial action is set to end on August 30.

"You will be aware that we have not issued any further notice for strike action which will currently end on 30 August," Unite general secretary Len McCluskey said in a letter to BA CEO Alex Cruz.

"This is in order to create a 'pause for peace' so that our respective teams can get around the table with a view to securing a mutually accepted resolution to the current dispute."

British Airways entered into a "wet-leasing" arrangement with Qatar Airways to borrow planes and staff during the strike, but has said that all passengers would reach their destinations during the industrial action.
