Morland Sanders investigates the background to the strike at British Airways. How has a dispute over reductions in cabin crew turned into a long-running and costly row? Union officials fear the dispute has the potential to cause acrimonious rifts between staff at BA - once dubbed the world's favourite airline. But managers say they have to cut costs and have put in place extensive plans to keep many routes operating. Travellers, though, face chaos and cancellations. The Report examines the financial problems facing BA - and asks if the industrial action will result in business and first class passengers taking their custom elsewhere. They make up the premium market that the airline needs to keep for its long-term survival. Producer: Sally Chesworth.
