Passengers were urged to contact their airlines and check their flight status before travelling.EasyJet said some of its flights were “unable to operate” because of the system failure and warned of “delays to flights across Europe.”At Heathrow, the airport’s website showed multiple cancellations and delays involving short-haul flights to European destinations.The exact cause of the technical failure was not immediately known.Catch the latest World News and Live updates.
