Almost 11.5 million passengers travelled through Dublin Airport in the first six months of the year – up 15.1% on the same period of last year.
The Dublin Airport Authority said that the volume of traffic to and from continental Europe had been particularly strong so far in 2015, as was the British market.
The airport was also seeing record numbers of transatlantic and transfer passengers, it said, boosted by new services from Aer Lingus and its regional operation.
Passenger numbers across Europe are up 4.5% in the six months, putting Dublin Airport’s performance well ahead of the regional average.
The DAA said it had the fourth largest passenger increase within its airport category, behind Athens, London Stansted and Istanbul Sabiha Gokcen.
Meanwhile, Ryanair said it grew its passenger numbers by almost one million in July when compared to the same month of last year.
The airline said it flew 10.14 million people during the month, up 11% on the 9.15 million passengers in July 2014.
It also increased its load factor - the percentage of seats filled on each flight - by four points to 95%.
Ryanair said its figures marked the first time an airline has carried more than 10 million international customers in one calendar month.
