United Airlines is adding a second daily flight from Dublin to New York's Newark airport, starting 24 April next.

Thus additional year-round service joins the airline's existing seasonal direct service from Dublin to Chicago, as well as seasonal direct services from Dublin to Washington Dulles and Shannon to New York Newark that are planned to resume next year.

The additional flight from Dublin is part of United’s largest transatlantic expansion in its history announced today, including 10 new routes and five new destinations.

"United is a valued customer serving Dublin Airport for more than two decades and we are particularly delighted to see this increase in frequency, it’s a very welcome boost to transatlantic connectivity" said Dublin Airport Managing Director Vincent Harrison.

Marcel Fuchs, United's Managing Director International Sales said they are excited to announce this increase in daily services from Dublin.

"The additional frequency strengthens our international route network and provides our customers from Ireland with even greater travel choice and convenient one-stop connections via our New York/Newark hub to other destinations across the Americas," he said.
