Passengers face delays because planes have been grounded at one of Europe’s busiest airports due to a problem with fuelling systems. More than 254 flights have been cancelled to and from Amsterdam’s Schiphol Airport and 446 flights delayed, according to Flightradar24. In a statement published on Wednesday evening, the airport said aircraft were unable to refuel because of a fault. “Planes at Schiphol cannot be refuelled right now,” read the statement. “Aircraft Fuel Supply, a third-party company that controls aircraft fuel supply, currently has a fault in their system. “As a result, your flight may be delayed or cancelled by your airline. “Schiphol and Aircraft Fuel Supply are working hard to find a solution. It is still unclear how long this will take, but it will definitely last into the evening. “We regret any inconvenience for travellers and airlines.” Passengers were urged to contact their airlines for overnight stay options. As a precautionary measure, the airport would have camp beds for those who would not find accommodation. At around 9:30 pm, the airport announced on Twitter that the fuel system was starting “cautiously and gradually.” There was confusion at the airport. Passengers were at their wits’ end, taking to Twitter to share videos of the crowds and chaos.
