British Airways has blamed a “technical issue” for disruption to its flights around the world, but said it expected to operate virtually a full schedule on Thursday.
Some long-haul flights into the UK’s two busiest airports, Heathrow and Gatwick, were cancelled or severely delayed overnight and the airline said there would be knock-on effects, including further delays.
About 45 flights due to land at Heathrow were delayed by more than 45 minutes by 9am. The longest delay was flight BA170 from Pittsburgh, US, which was expected to arrive more than 12 hours late. Passengers on some cancelled flights, including from Mexico and Japan, were set to arrive more than 24 hours behind schedule.
BA said it was working hard to resolve an unspecified “technical issue” affecting inbound long-haul flights and that it had rebooked customers on alternative flights with hotel accommodation for those unable to continue their journeys
A BA spokesman said later on Thursday morning: “We plan to operate a full flight schedule today.
“There may be some knock-on delays to flights and we are advising customers to check ba.com for the latest flight information.
“We are sorry for the disruption to customers who have been affected.”
It is the latest in a series of systems failures to hit the airline in recent months. In August, an IT glitch led to the cancellation of more than 100 flights and disrupted the travel plans of tens of thousands of passengers.
BA’s system resilience has been the focus of particular scrutiny since a major incident in May 2017, in which all flights from its major London airports were cancelled, stranding tens of thousands of passengers. A power outage caused by an engineer overriding the electrical failsafe was blamed by executives.
