Amsterdam's Schiphol airport has asked airlines to cancel flights between 4pm and 11pm local time today due to labour shortages, it said in a statement.
The move comes as one of Europe's busiest airports again grapples with long queues, leading to some travellers missing their flights.
Travel at Schiphol has been disrupted on and off since April. Hundreds of flights have been cancelled, and queues have become routine.
"After weeks of improvement, Schiphol did not expect to have to take these measures," the airport's statement said.
"Employees in the terminal are working as hard as they can to ensure that everyone can travel today, but unfortunately there is a chance that travelers will miss their flight due to long waiting times," it added.
Airlines that comply with the request to cancel flights will be compensated, it said.
