Passengers at Amsterdam's Schiphol airport are facing long waits after a power outage temporarily knocked out its check-in systems.
The outage that hit parts of Amsterdam early on Sunday morning prompted authorities to briefly shut roads and a rail link to the airport on the outskirts of the Dutch capital.
The airport says on its website that check-in systems were restored early today, but warned passengers to check the status of their flights for updates.
The airport says incoming flights "will be reduced in capacity" from 9-11am local time and that several departing flights have been cancelled or delayed.
The Dutch power grid administrator, Tennet, says it is investigating the cause of the outage.
