Shannon Airport welcomed over 1.5 million passengers last year, up over 300% on 2021, and an 88% recovery on 2019 passenger levels.
Mary Considine, CEO of the Shannon Airport Group said the recovery has exceeded expectations.
"The accelerated pace of the rebound in air travel from Shannon has exceeded our expectations and shows the pent-up desire for international travel following the lifting of pandemic travel restrictions," said Ms Considine.
European services recovered strongly last year, with over 532,000 passengers travelling through Shannon. This was up 7% on the pre-pandemic levels recorded in 2019 and up 225% on 2021.
When it comes to its UK services, Shannon recorded over 638,000 passengers in 2022, an increase of 309% on the previous year.
Transatlantic services returned last March after two years, with almost almost 240,000 passengers on services to New York (JFK), Boston and Newark.
The Shannon Airport Group said a further boost is expected from May 2023, when a new daily nonstop seasonal service to Chicago begins.
"The introduction of our new, faster, airport security screening facility, continued to have a positive impact in 2022," said Ms Considine.
"The new system eliminates the 100ml only rule, halving the time spent going through security screening.
"We have seen an increase in people from all over the country using Shannon Airport, as they now realise how easy it is," she added.
