BA have added a very nifty tool to their website. You are able to view wether you and the flights you are booked on are affected.
Up to the minute information on all flights for yesterday, today and up to 8 days in advance.
During the strike period this information is the most up to date available on the status of your flight. Please search by flight number or if you search by route or airport, click the estimated button in the status column once your results are displayed.
