Aer Lingus warns customers travelling to London Heathrow to "expect delays" due to freezing fog conditions
Dublin Airport and Ryanair have also issued fresh advice to passengers.
As Ireland and the UK continue to face a cold snap of weather, Aer Lingus has issued an update to its customers.
The airline has said that while it plans to operate the majority of its flights scheduled on Sunday (11 December), it is experiencing challenges with its London Heathrow operation due to freezing fog conditions.
Aer Lingus stated that, as a result of this, it has been forced to cancel some of its London Heathrow services for Sunday and that it is now advising customers travelling to the airport to "expect delays on services that can operate".
The airline added that some of its UK regional services have also been cancelled due to ongoing weather conditions.

"We continue to monitor the weather conditions and wish to reassure customers that our teams are doing all they can to minimise any disruption to their travel plans," an Aer Lingus statement reads.
"Customers travelling today can check the status of their flight on aerlingus.com before travelling to the airport.
"Our Customer Care team will contact any customers directly whose flight has been cancelled and will work to re-accommodate them on the next available services.
"Should customers require further assistance our Customer Care team is available via Aer Lingus social channels and via our Call Centre."
Meanwhile, Ryanair has said that, due to slightly improved weather conditions on Sunday, it is only experiencing "some very minor delays" to its flights from UK and Irish airports.
"While our teams are working hard to minimise any disruption caused to our customers as a result of the icy weather, which is entirely beyond our control, Ryanair advises all customers flying from UK and Irish airports today to check the Ryanair website/app for flight status updates before travelling," it added.

Dublin Aiport has also issued a statement confirming that the majority of its first-wave departures took off on Sunday "without any undue delays".
"Any delays were due to aircraft that had to be safely de-iced by the airlines and their ground handling operators," it said.
"Please continue to check the status of your flight with your airline in advance of travel."
