THOUSANDS of passengers at Dublin Airport faced delays due to heavy fog in the area.
More than 60 flights were delayed both arriving and departing last night due to poor visibility on the ground.
Although the delays were generally around an hour or less, passengers on several Aer Lingus flights faced delays of up to two hours.
Dublin Airport Authority (DAA) spokeswoman Siobhan Moore said that while most flights were facing delays, there were no cancelled flights.
"When dense fog occurs, Air Traffic Control slows everything down for safety reasons because visibility on the ground is so bad," she told the Irish Independent, adding "It's standard procedure."
Ms Moore said it remains to be seen if the delays will have a knock-on effect today or if more flights will be affected, which depends on when the fog lifts.
