Dublin Airport has been experiencing difficulties as airlines struggle to deal with staffing shortages due to Covid-related absences.
Speaking on Virgin Media's The Tonight Show on Monday, DAA CEO Dalton Philips said there is a huge amount of Covid in the industry at the moment.
He said: "Now we are seeing a huge amount of Covid going through the industry. You're seeing massive levels of flight cancellations. In fact, 88 flights in and out of Dublin have been cancelled in the last five days, that impacts about 13,000 people. Clearly, we can't control the airlines and the challenges they have around Covid, but from our side, from a security point of view, prudent planning."
