Belfast International Airport flying high as number of passengers expected to hit 5m this year
And managing director Graham Keddie has said that it could break the five million passenger barrier by the end of the year.
He also revealed to the Belfast Telegraph that the airport has capacity for another million passengers.
Passenger traffic has been boosted by increased capacity from easyJet, transatlantic airline United and holiday airlines Jet2 and Thomas Cook.
And the announcement that Ryanair is bringing eight new routes to the airport will also help to grow passenger numbers as the bulk of its flights go live in the autumn.
And combined with passenger traffic from Belfast City Airport - which is also expected to increase this year - Northern Ireland's two main airports could be flying nearly eight million passengers by the end of 2016.
The new figures show that more than 370,000 passengers travelled through the airport last month.
It was also confirmed that the upward trend was continuing, as passengers had increased by 16% since January.
