British Airways cancels flights, passengers stranded

British Airways canceled all flights from London's Heathrow and Gatwick airports on Saturday as a global IT failure upended the travel plans of tens of thousands of people on a busy U.K. holiday weekend.
The airline said it was suffering a "major IT systems failure" around the world. Chief executive Alex Cruz said "we believe the root cause was a power-supply issue and we have no evidence of any cyberattack."
The problem comes on a bank holiday weekend, when tens of thousands of Britons and their families are travelling.
Passengers at Heathrow reported long lines at check-in counters and the failure of both the airline's website and its mobile app. BA said the crash also affected its call centers.
Passenger Phillip Norton tweeted video of an announcement from a pilot to passengers at Rome's Fiumicino airport, saying the problem affects the system that regulates what passengers and baggage go on which aircraft. The pilot said passengers on planes that have landed at Heathrow were unable to get off because there was nowhere to park.
One person posted a picture on Twitter of BA staff writing gate numbers on a white board.
"We've tried all of the self-check-in machines. None were working, apart from one," said Terry Page, booked on a flight to Texas. "There was a huge queue for it and it later transpired that it didn't actually work, but you didn't discover that until you got to the front."
Another traveler, PR executive Melissa Davis, said her BA plane was held for more than 90 minutes on the tarmac at Heathrow on a flight arriving from Belfast.
She said passengers had been told they could not transfer to other flights because "they can't bring up our details."
Some BA flights were still arriving at Heathrow on Saturday, although with delays.
American Airlines, which operates code-share flights with BA, said it was unaffected.
BA passengers were hit with severe delays in July and September 2016 because of problems with the airline's online check-in systems.
Emily Puddifer, who was trying to travel to Milan from Heathrow, said her weekend away has been canceled. Her friends, who were going from Liverpool with a different airline, made it to Milan.
Reached via Twitter, Puddifer said in an email she understands that such technical failures happen. What she didn't understand, she said, was why there were "no announcements, no messages on the boards" about what was going on. Displays showing flight times had the words "please wait" next to flights instead of information about delays or cancellations.
Puddifer said passengers found out about the cancellations from news reports. It was chaos just to get out of the airport as people followed crowds but no one knew where to go, she said. Finally, she made it out, and she considered herself lucky not to have checked luggage.
There are "thousands of people there with no idea where their bags are or what to do," she said.
