SYSTEMS DOWN Airline working to restore service after major outage

British Airways said Sunday that it was still working to restore its computer systems following a major system failure that caused the airline to cancel all flights from London airports. "Work continues to restore all of our IT systems but we expect some further disruption today," BA said in a statement. The airline offered to refund or rebook customers affected by the IT failure and said it hopes to operate at a "near normal schedule" at Gatwick and the "majority of services" from Heathrow on Sunday. British Airways flights from London's Heathrow and Gatwick airports were canceled Saturday because of global computer problems, resulting in mass confusion and chaos for tens of thousands of travelers on a busy holiday weekend. The airline said it was suffering a "major IT systems failure" around the world.
