Cabin crews of British Airways began a three-day strike today, forcing the airline to cancel 1100 flights worldwide. Talks between the Unite trade union and British Airways broke down Friday, which resulted in the strike. Among the issues being argued is the plan by British Airways for a two-year pay freeze and to cut the number of staff onboard long-haul flights. Another three-day strike is planned March 27th. Each strike is expected to cost the airline millions of dollars in lost revenue and brand damage.To check the status of any worldwide flight, click here.
