Cork Airport saw a 10% increase in passenger numbers last month when com[pared to February 2018.
More than 150,000 passengers used the airport in February which is an increase of 14,000 on the same month last year.
The airport is also set to welcome 40,000 passengers this St Patrick's Weekend.
The news comes as Ryanair also announced a new twice-weekly service between Cork and Katowice in Poland as part of its winter 2019 schedule. The service will begin in October.
Cork Airport Managing Director Niall MacCarthy said the passenger numbers of 151,000 last month is due to the support of passengers travelling from across Cork choosing to fly direct from Cork Airport.
"We are seeing a keen interest from passengers in continental European destinations, including Aer Lingus’ new year-round service to Lisbon and the daily Air France service to Paris, which has strong onward connections.
“March is also indicating strong growth and this St. Patrick’s Weekend we will welcome 40,000 passengers through Cork Airport. In total, 2.6 million will use Cork Airport this year, a projected growth of 8%.
Cork Airport has added nine new routes in the past year. Along with the new Katowice, Ryanair has also announced new services to Naples, Budapest, Malta, Poznań and London Luton from Cork Airport in the past 12 months.
The airline’s passenger numbers at Cork are forecast to rise by 17% in 2019, its largest increase among all Irish airports.
Aer Lingus has also added Nice and Dubrovnik to its summer 2019 schedule while Air France has upgraded its daily service between Cork and Paris with a larger aircraft to add more capacity.
