Low temperatures leading to more travel disruption
Kildare passengers are being advised to check with their airline as the cold snap has resulted in the cancellation of 50 flights in and out of Dublin Airport.
The DAA says the airport is fully open and operational - but there are knock-on-delays from weather disruption yesterday.
The disruption is being felt around Europe too - with Manchester Airport's runways temporarily closed because of snow.
Meteorologist for Met Eireann, Gerry Murphy, says there's no sign of it warming up any-time soon.
