Plan ahead:

"British Airways PLC cabin crew plan to strike for a total of seven days this month, potentially disrupting thousands of travelers ahead of Easter holidays, after talks with management over changes to pay and working conditions broke down." (The Associated Press)

The dates, says The Guardian, are three days starting March 20 and four days starting March 27. It adds that:

"BA carries around 75,000 passengers a day and the strikes will affect hundreds of thousands of passengers. The airline has pledged to run a significant skeleton service with the help of 1,000 volunteer cabin crew."
