Five Aer Lingus flights from Dublin Airport have been cancelled today, due to a spike in Covid cases among staff.
They are three flights to London Heathrow, one to Hamburg and one to Berlin.
The airline was forced to cancel a number of flights yesterday, for the same reason.
Travel writer Eoghan Corry says there could be even more cancellations today:
"Long term are getting 24 hours, or overnight notice and it gives passengers notice that they don't show up at the airport."
"The real problem with the short term cancellations is that people have already been through the airport, and had the drama of all those queues."
