British Airways is still cancelling flights in the aftermath of a three-day strike by cabin crew. The airline's website shows it has cancelled nearly 200, or more than 19 per cent, of flights that had been scheduled up to midnight today. BA is reviewing its schedule for a further four-day strike beginning on Saturday. <br/><br/>In a statement issued to the London Stock Exchange about its operations over the weekend, BA said it estimated the three-day strike had cost the company 7 million pounds a day. The strike action is the latest episode in a long-running dispute over changes to pay and conditions by BA that union Unite claims are being unfairly imposed on its members.
