Cork Airport saw the biggest jump in traffic last month of all Irish airports.
Passenger numbers for August increased 7.2% over the same period in 2016.
This growth surpassed that at Dublin Airport which experienced growth of 6% in the month.
The addition of year-round transatlantic flights with Norwegian to Boston Providence coupled with four other new UK and European routes have contributed to strong growth at Ireland’s second busiest.
Cork Airport said their summer season has been particularly strong since new routes commenced last May and will continue through to the end of October when the winter schedule starts.
Year to date passenger numbers have grown by 47,500 to 1.6 million compared to the same period last year and will result in further growth of 4% this year building of the 8% achieved in 2016.
Cork Airport’s Managing Director, Niall MacCarthy said: “We are delighted to be the Republic of Ireland’s fastest growing state airport in passenger number terms in the key Summer month of August."
He pointed to cheaper parking, shorter walking distances and less road traffic and the reason more passengers from Munster and south Leinster are choosing Cork over Dublin Airport.
