British Airways on Saturday cancelled most flights out of London’s Heathrow, Gatwick airports as a computer system broke down, causing chaos for travellers at the start of a three-day weekend in the UK. “We have experienced a major IT system failure that is causing very severe disruption to our flight operations worldwide,” the airline said in a statement, without specifying what caused the outage or how long it will take to fix.
“We are working to resolve the problem as quickly as possible,” the carrier said.
Heathrow Airport said it was “working closely” with British Airways to solve the issue.
