New figures released today show that 3.34 million passengers travelled through Dublin Airport in September, in line with the same month last year.
In the first nine months of 2026, just under 29 million passengers travelled through Dublin Airport, an increase of 4% on the same time last year.
Around 17.4 million of those passengers travelled through Terminal 1, while almost 11.6 million travelled through Terminal 2, the airport noted.
The most popular routes from the airport in September were Heathrow, Amsterdam, Manchester, Malaga and Gatwick.
Today’s figures show that Dublin Airport saw its three busiest-ever September days during the month, with Sunday 13 September, the busiest of all. A total of 128,600 passengers travelled through its two terminals on that day – a 4% increase on the previous busiest September day.
Dublin Airport said its strong September performance was supported by a significant increase in transfer activity, with the number of passengers connecting to other destinations through its route network up 37% on September last year.
A total of 493,000 passengers travelled on routes between Dublin and North America in September, 3% higher than the same month last year, while traffic on UK routes was up 2%.
Gary McLean, Managing Director of Dublin Airport, said that September brought an end to its busiest-ever summer period, with almost 15 million passengers travelling through its two terminals since the end of May.
“Passenger demand was supported by a number of notable events, including Ireland’s EU Presidency, which continues to bring politicians and delegates from all over the world to Ireland,” Mr McLean said.
“Golf was also a big driver of September’s numbers, with thousands of golf fans flying in from around the world for the Walker Cup and Irish Open at Lahinch and Doonbeg respectively. The return of business and student travel after the summer also helped drive demand,” he added.
Mr McLean said the airport also continues to see strong demand for its transatlantic routes, highlighting the need to further improve its US preclearance facility.
