British Airways canceled all Saturday flights from London’s two biggest airports after “a major IT system failure” caused severe disruption to flight operations worldwide, the airline said.
“Our IT teams are working tirelessly to fix the problems,” British Airways CEO Alex Cruz said in a video posted on Twitter.
“We believe the root cause was a power supply issue and we have no evidence of any cyberattack.”

The airline initially canceled only flights before 1 p.m. ET (6 p.m. BST) at Heathrow and Gatwick.
“We are working hard to get our customers who were due to fly today onto the next available flights over the course of the rest of the weekend,” the airline said in a statement Saturday afternoon. “Those unable to fly will be offered a full refund.”
The system outage — on Britain’s spring bank holiday weekend — has “affected our call centers and our website but we will update customers as soon as we are able to,” the airline said.
“We are extremely sorry for the huge inconvenience this is causing our customers and we understand how frustrating this must be, especially for families hoping to get away on holiday,” Cruz said.
