Dutch airspace is to remain closed to all air traffic until 6.00 hours on Saturday morning at least, the transport ministry said on Friday afternoon.

‘The volcanic eruption on Iceland is still a risk for air traffic,’ the ministry said in a statement after consultation with air traffic controllers, the KNMI weather bureau and air safety experts.
Europe’s intergovernmental air control agency, Eurocontrol, told the BBC it ‘expects around 11,000 flights to take place today in European airspace. On a normal day, we would expect 28,000.’
Flights have been halted because tiny particles of glass and stone in the volcanic ash can cause aircraft motors to jam up.
Disruption
International trains from the Netherlands were fully booked on Friday as passengers turned to alternative forms of transport to make their journeys. Dutch Rail (NS) said it was running extra trains to Paris and Germany to cope with demand.
And international bus service Eurolines said it was running extra bus services. In particular there is strong demand for trips to London, the Volkskrant reported.
Some stranded passengers are even resorting to renting cars to get to their destination, even though the charges can run up to €2,000 because the car needs to be brought back by someone else, the paper said.
