The first of 4 announced strikes is scheduled to begin May 18, 2010 with subsequent strikes starting May 24th, May 30th and June 5th. We expect high call volumes during this time, and want to provide our customers with online access to learn of the most recent and quickly changing updates on British Airways change and cancellation policies.
