British Airways and cabin crew union Unite will make a fresh attempt to remove the threat of further strikes in talks at conciliation service Acas this week.

The dispute between the airline and union over disciplinary action against striking cabin crew remains unresolved and Unite retains the option of holding a fresh ballot that could see strikes resume in the autumn.

However, the prospect of fresh action appears to be receding. BA chief executive Willie Walsh met Unite joint general secretaries Tony Woodley and Derek Simpson late last week to discuss grounds for a resolution.

Walsh insists he will operate all long-haul services from Heathrow during any fresh strike.

More than 6,300 BA cabin crew took part in 22 days of strikes over work changes in March, May and June – the longest dispute of its kind in the airline’s history.
