Dublin Airport said it recorded its busiest ever day last month when a total of 120,585 passengers travelled through the airport on Sunday July 30.
July saw just over 3.4 million passengers travel through the airport - that number was 13% higher than the same month in 2022 and on a par with July 2019.
That figure for July at Dublin Airport included 205,000 transfer and transit passengers.
All 31 days in July saw passengers numbers of more than 100,000, according to daa, which operates Dublin and Cork airports.
Meanwhile, Cork Airport recorded its busiest July since 2008 with 301,000 passengers flying to and from the country's second busiest airport.
July passenger traffic at Cork Airport also represented a 13% increase on July 2022.
"The busiest days in July normally come in the middle part of the month, but this year passenger numbers continued to rise as the month went on at both Dublin and Cork airports," Kenny Jacobs, the CEO of the daa, said.
"The summer so far has been really smooth at both Dublin and Cork airports which is all down to the phenomenal efforts of the teams working in both airports," he noted.
99.6% of passengers at Dublin Airport got through security in less than 20 minutes during the month of July.
"Indeed, during June and July combined - the first two months of the really busy three-month summer period - 99 out of every 100 passengers has got through security screening in under 20 minutes, which is a performance that would rival any other capital city airport in Europe this summer," Kenny Jacobs said.
He also said that Cork Airport continues to offer a really easy and hassle-free airport experience for passengers from Munster and South Leinster.
"Practically all passengers (99.9%) cleared security screening in less than 20 minutes with nine out of ten passengers clearing security in less than 10 minutes," he said.
"It is also great to see strong performance on new summer routes, namely Rome, Seville and La Rochelle. This clearly shows the strong appetite amongst our passengers in Munster and South Leinster for new and exciting destinations on the continent," he added.
