LONDON (AP) -- British Airways said "many" of its IT systems were back up and running Sunday, but travelers still faced cancellations and delays after a global computer failure grounded hundreds of flights.
BA chief executive Alex Cruz said the airline was running a "near-full operation" at London's Gatwick Airport and planned to operate all scheduled long-haul services from Heathrow. But he said there will still be delays, as well as some canceled short-haul flights.
BA canceled all flights from Heathrow and Gatwick Saturday after the IT outage, which it blamed on a power-supply problem. The glitch threw the plans of thousands of travelers into disarray, on what is a holiday weekend in Britain.
BA operates hundreds of flights from Heathrow and Gatwick on a typical day - and both are major hubs for worldwide travel.
Cruz apologized in a video statement, saying "I know this has been a horrible time for customers."
