New figures from the Central Statistics Office show a big increase in the level of overseas travel in July compared to June, but the number still remains far below pre-Covid levels.
The CSO reported 380,700 overseas passenger arrivals and 428,600 overseas passenger departures in July of this year.
This compares with 160,000 arrivals and 199,100 departures in June and marked monthly increases of 137.9% and 115.3% respectively.
However, the CSO said that for every overseas traveller in July of this year there were over five in pre-pandemic July 2019, when there were a total of 2,225,900 arrivals and 2,183,900 departures.
Today's figures show that of the 380,700 people arriving in Ireland in July, 85.8% came by air and 14.2% arrived by sea.
Of the 428,600 people leaving Ireland, 89.6% departed by air and 10.4% left by sea.
The CSO said that continental route accounted for most passenger traffic, with 57.2% of arrivals and 67% of departures.
The cross-channel route was next busiest, with 32.3% of arrivals and 25.8% of departures, while the transatlantic route saw just 7% of arrivals and 4.3% of departures.
But in terms of specific routing countries for travelling directly to Ireland, Great Britain proved most important, accounting for 122,700 arrivals and 110,400 departures.
Spain was the second busiest routing country, with 42,300 arrivals and 66,400 departures. Poland was third with 26,000 arrivals and 36,500 departures.
So far this year, the CSO said that 919,800 people arrived in Ireland from overseas and 1,036,100 people left the country.
It said this compares with 3,414,000 arrivals and 3,448,600 departures in the same time in 2020, and 11,565,100 arrivals and 11,692,100 departures in 2019.
