Planes at Schiphol cannot be refuelled right now. Aircraft Fuel Supply, a third-party company that controls aircraft fuel supply, currently has a fault in their system.
As a result, flights may be delayed or cancelled by your airline.
Schiphol and Aircraft Fuel Supply are working hard to find a solution.
Reduction in landing rate is due to ramp congestion (limited parking available) ; the airport is not currently able to accept additional aircraft that do not require refueling.
It is still unclear how long this will take, but it will definitely last in to the evening. The situation is not expected to improve until tomorrow morning.
