Conciliation service Acas is putting forward new proposals to try and end the protracted dispute between British Airways and cabin crew members of the Unite union.

The move emerged after the union warned of a ballot for further strike action which could hit flights during the August peak.

Fresh talks between the two sides are expected to take place this week but the timing and location is being kept under wraps to avoid a repeat of disruption to previous discussions.

An Acas spokesman said: “Acas and the TUC have continued to maintain contact with both BA and Unite since talks were adjourned. It is expected that a date will be agreed shortly for talks to resume.”

Members of Unite have taken 22 days of strike action since March costing the airline at least £150 million.
