Passenger Matthew Creed, 26, became stuck at Schiphol Amsterdam Airport yesterday after his flight with KLM Royal Dutch Airlines to Edinburgh was cancelled.

Matthew said: “They were helping people for a long amount of time, there were long queues, and there were only four or five agents trying to help people.
“Then they just kind of said we’re closing all of their desks and everybody needs to find their own accommodation or find out their own way to sort things out.
“We heard that there was a gate at the end of the airport where they were putting out pillows and blankets and things, so that’s where we had to sleep last night… which wasn’t ideal.”
At least 281 flights – including departures and arrivals – were cancelled yesterday at the UK’s six busiest airports.
