British Airways has blamed a “technical issue” for disruption to its flights around the world.
Flights to and from the UK’s two busiest airports, Heathrow and Gatwick, appear to be among those affected on Thursday.
A spokeswoman for the airline said: “Our teams are working hard to resolve a technical issue which is affecting some of our flights, and we have rebooked customers on to alternative flights and offered hotel accommodation where they have been unable to continue their journeys last night. We are very sorry for the disruption to their travel plans.”
Customers were advised to check ba.com for the latest flight information and ensure their contact details were up to date on their booking.
