Aer Lingus has announced the cancellations of some flights bound for London's Heathrow from Dublin Airport due to 'freezing fog conditions' in Britain.
The airline also warned passengers to expect delays on non-cancelled flights and further cancellations of other UK regional services.
It follows two days of extensive delays, with one group of passengers waiting almost 15 hours to board a flight to Barcelona.
Aer Lingus has advised passengers to check the status of their flight before travelling to the airport.
All flights into and out of Cork airport are running to schedule.
