Last year saw 21.7m passengers travel through Dublin Airport according to the DAA, an 8% increase on 2013.
Long-haul traffic saw strong growth, with a 14% rise in the numbers travelling to North America and the Middle East during the year.
Meanwhile, short-haul travel was 7% higher year-on-year.
Airlines introduced 24 new routes to Dublin Airport last year, while extra flights were also added to 34 existing routes during the year.
Dublin Airport’s managing director Vincent Harrison said these new flights helped bring 1.5m extra passengers through their doors.
He said 14 new services were planned for this year - including routes from Vueling, WOW Air and Transavia – and the airport hoped to see strong passenger numbers again this year as a result.
