The numbers of passengers using Cork Airport last year fell by 80% last year as a result of the Covid-19 pandemic.
530,000 people used the country's second largest airport over the twelve months, down from 2.6m the previous year.
Over the four years from 2015 to 2019, the number of passengers at Cork Airport had grown by 25%.
"2020 has been a year like no other for Cork Airport," said Niall MacCarthy, Managing Director of the facility.
"We have gone from over fifty routes across eight scheduled airlines to two routes with two airlines. Our story is no different than other airports and other businesses across the world."
The biggest drop in passenger traffic was to and from Southern Europe, with volumes declining by 87% year on year.
Western European traffic dropped by 80%, with the numbers flying to and from UK provincial cities collapsing 81%.
"No doubt, we have a long journey to travel back as we regrow our network out of Cork and become an engine of growth for the South of Ireland economy once again," Mr MacCarthy said.
"We are already working on our recovery plans with the support of our parent group daa so that we can rebuild our UK and Continental European networks as soon as possible and reconnect Cork with the world, when it is safe to do so and when the demand is in place."
Cork Airport was among those that received operational and capital financial assistance from the Government to help it get through this year.
