Thousands of passengers are facing delays at Dublin airport for the second day running.
Up to 20 flights have been delayed with some flights delayed for up to 12 hours.
Hundreds of passengers were delayed at Dublin airport yesterday when heavy fog caused the cancellation of 25 flights and delayed arrivals from the UK.
The majority of the cancelled flights were Aer Arann and Ryanair services. Most other flights at the airport were experiencing delays of between one and two hours.
