Additionally, United expanded its second daily New York/Newark flight to the winter months.
The airline will now operate more flights and seat capacity from Dublin Airport than any other US carrier.
“This significant expansion further underlines the importance of Dublin within United’s global network,” said Karolien De Hertogh, United’s UK and Ireland sales director.
“Our customers in Ireland will benefit from even greater travel choice in the winter season, with the possibility to seamlessly connect via our hubs in New York/Newark, Chicago O’Hare and Washington DC.”
It marks a scaling up of Ireland-US direct flights in recent months.
United doubles the frequency it operates between Dublin and Washington DC this summer, adding a second daily service.
It also boosted capacity on its Dublin-Chicago route by deploying a new Boeing 787-8 Dreamliner jet.
“More capacity to Newark and Chicago O’Hare airports is great news for our passengers,” says Gary McLean, Dublin Airport MD.
“The move to almost year-round operations for the second daily Newark service and year-round for the daily Chicago flight is a clear signal of the strong demand.”
Overall, the seat capacity to and from the Irish capital is up by 50% next year, compared to 2024.
