New figures from airport operator daa show that passenger numbers at Cork Airport jumped by 25% in March, while they increased by 9% at Dublin Airport.
Daa said a total of 2.9 million passengers travelled to and from the country's two busiest airports during the month of March, with a total of 2,622,237 million passengers using Dublin Airport and 226,250 passengers using Cork.
Dublin Airport operated a total of 19,310 flights last month, while Cork operated 1,552 flights.
95% of passengers went through security at Dublin Airport in less than 20 minutes, while all of Cork Airport's passengers went through in less than 20 minutes, daa noted.
The busiest day of the month for both airports was Friday, March 29 as the Easter weekend kicked in.
Today's figures also show that London Heathrow was the most popular destination from both airports last month.
Kenny Jacobs, the chief executive of daa, said that Dublin Airport's passengers numbers last month were boosted by some high-profile sporting events that took place in the Aviva, including the Six Nations clash against Scotland and the soccer friendlies against Switzerland and Belgium.
He also said that plenty of fans and punters flew out to the Ireland v England rugby game in Twickenham and the Cheltenham Racing Festival.
Mr Jacobs noted that a very extensive summer schedule has just started at Cork Airport, with a new Ryanair service to Brussels starting last weekend.
"Other new Ryanair services to Rhodes and Zadar will take off in June and Air France will add additional capacity on their key hub connections to Paris Charles de Gaulle for July and August," Mr Jacobs added.
