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 to five the total number of cancellations by the airline for tomorrow, while six have been cut today.
Aer Lingus says it's working to re-accommodate affected passengers on the next available services.
Travel expert Michelle Walsh Jackson says travellers affected by the cancellations do have rights.
"They are protected by certain rights such as EU 261 and if they are stuck and have to get accommodation, they will be looked after.
"Aer Lingus put this out actually on all their ticketing arrangements with links to EU 261 with what you do in such a situation."
