Fewer from Northern Ireland used Dublin Airport in 2017, says report
The number of Northern Ireland people using Dublin Airport fell back from a 990,000 high in 2016 to 950,000 last year, according to new figures.
Data for 2017 from the Northern Ireland Statistics and Research Agency also showed that London airport Gatwick remains the province's most popular air route.
Overall, air passengers increased to 8.6m during 2017, almost 0.5 million more than 2016.
Airports in Britain accounted for the biggest share of the air flow in and out of Northern Ireland last year. A total of 982,790 people flew between Gatwick and Belfast International Airport - which is led by Graham Keddie - during the 12 months.
That put it well ahead of Heathrow, which saw 686,085 fly to and from George Best City Airport during the same period.
The research released by Nisra put Liverpool John Lennon Airport at third in the list with 490,613, ahead of Stansted in Hertfordshire on 376,512. Luton (340,109), Manchester (287,253) and Edinburgh (284,895) also proved popular.
