Last month Shannon airport warned that traffic could fall by up to 70% this year and that it would take at least three years for passenger numbers to return to 2019 levels.
Prior to the coronavirus pandemic, Shannon had already seen a dip in traffic, due to the grounding of the Boeing 737 MAX and a Ryanair cost-cutting programme, but 2020 had been looking positive.
Last month, however, United Airlines dropped its Shannon-Newark service. And the airport's most popular route, London-Heathrow, has been suspended due to Covid-19 restrictions, despite Aer Lingus opting to retain their Heathrow services from other airports.
