British Airways has resumed flights from Britain’s two biggest airports after a global computer system failure triggered chaos, leaving planes grounded and thousands of passengers queuing for hours.
BA said it aimed to operate a near normal schedule of flights from Gatwick airport and the majority of flights from Heathrow on Sunday.
But Heathrow Airport told passengers not to travel to the airport unless they were rebooked on other flights. It said it expected further delays and cancellations of BA flights on Sunday.
British Airways cancelled all of its flights from London’s Heathrow, Europe’s busiest airport, and Gatwick on Saturday after a power supply problem disrupted its flight operations worldwide and also hit its call centres and website.
Alex Cruz, the chairman and chief executive of BA, part of Europe’s largest airline group IAG, said there was no evidence of any cyber attack. He said a power supply issue was to blame.
Thousands of passengers were left waiting for hours in departure halls at the airports on a particularly busy Bank Holiday weekend.
While other airlines have been hit by computer glitches, the scale and length of BA’s computer problems were unusual.
Delta Air Lines cancelled hundreds of flights and delayed many others last August after an outage hits its computer systems. Last month, Germany’s Lufthansa and Air France suffered a global system outage which briefly prevented them from boarding passengers.
