Thousands of British Airways passengers are facing disruption to their journeys as the cabin crew strike enters its third and busiest day. The Unite union says only 300 of the 2,200 cabin crew scheduled to work during the weekend turned up. It says support for the strike is solid, leaving 140 planes parked at Heathrow.<br/><br/>The Unite union has appealed to the board of British Airways to try to resolve the increasingly bitter dispute between the airline and its cabin crew. But BA says nearly 98 per cent of staff reported for work at Gatwick and more than half showed up at Heathrow. <br/><br/>BA claims an increasing number of crew are ignoring the strike call and that it has been able to add extra services. Cabin crew are striking over staffing and pay changes. They also plan to walk out for four days from 27 March.
