Aer Lingus says four more flights from Dublin Airport won't operate tomorrow due to Covid related staffing issues.
They include three outbound flights to Heathrow, Munich and Dusseldorf.
It brings the total number of cancellations for tomorrow to five, while six have been cut today.
Aer Lingus says it's working to re-accommodate affected passengers on the next available services.
As of yet, Aer Lingus flights from Cork have not been affected.
Travel expert Michelle Walsh Jackson says travellers affected by the cancellations do have rights:
"People will be affected on the ground but they are protected with certain rights such as EU261. If they are still going to have to get accommodation, they will be looked after and Aer Lingus put this out on all their ticketing arrangements, links to EU 261, listing what you do in such a situation."
