Aer Lingus cancelled six return flights from Dublin Airport today, due to a spike in Covid cases.
Two flights will be cancelled tomorrow.
In addition, due to a mandate from London Heathrow Airport Authority, one return flight to Dublin Heathrow tomorrow, has also been cancelled.
In a statement, the company says their teams are working to secure alternative travel options for customers in each case and are apologising to those impacted.
