British Airways cabin crew have begun a fresh five-day strike, the third and last in their current series of walkouts.
The strike, due to last until next Wednesday, is the latest stoppage in a long-running dispute.
The disagreement centres on pay, staffing levels and working conditions.
With no sign of a breakthrough between BA bosses and the leaders of the Unite union, the union has also threatened to ballot for more strikes in July.
The airline has said it plans to fly more than three-quarters of customers who booked flights – which amounts to 65,000 people a day over the strike period. It maintains that a growing number of strikers have been returning to work.
