The first passengers will begin using Dublin Airport’s new Terminal 2 in October, the Dublin Airport Authority (DAA) has said.
This will be part of the testing process for the new facility, which then will opened fully a month later.
Declan Collier, DAA’s chief executive, said the main construction phase at the terminal is near completion and that the initial flights will be used to test its systems and processes.
He went on to say that passengers travelling on cheap flights to Dublin will have a transformed experience of the Irish capital’s airport.
Ireland was particularly affected by the recent volcanic ash disruption, when the country’s airports were closed for six days.
"About 3,200 flights were cancelled at Dublin, Cork and Shannon airports and up to 400,000 incoming and outgoing passengers were affected," Mr Collier added.
Dublin is one of the ten busiest airports in Europe and accommodates an average of 60,000 passengers a day.
