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 travelers affected by the cancellations do have rights.
"People will be effected on the ground but they are protected with certain rights, such as EU 261.
"If they are stuck and they have to get accommodation, they will be looked after.
"Aer Lingus put this out in all their ticketing arrangements, links to the EU261 and what you do in such situations."
