The runway at Luton Airport was closed for about an hour this morning and there have been delays to some flights, a spokesman for the airport said.
The runway was de-iced and has now re-opened but passengers are warned that there could be further delays to flights as a "knock-on effect".
We had to close the runway for about an hour this morning as a precautionary measure. I think the snow took everyone by surprise this morning.
There have been a couple of delays this morning and we expect there to be a knock-on effect just as we get the service back up and running.
Passengers are advised to check with their airline and the airport's website before they travel.
