Aer Lingus has announced a new transatlantic service between Dublin and Seattle, which will fly four times a week from next May.
The route is the 15th transatlantic service from the airline and the sixth to be announced since it was acquired by IAG in 2015.
The new routes include Los Angeles, Newark, Hartford, Miami and Philadelphia.
The airline said the Seattle route will add 50,000 additional seats to its transatlantic programme for next summer, with its total 2018 transatlantic capacity now reaching more than 2.75 million seats.
Seattle is home to some of the largest technology companies, including Microsoft and Amazon, and is also the home of Boeing and coffee chain Starbucks.
Aer Lingus said its expanding transatlantic services has resulted in the creation of 600 jobs at the airline.
It added that its fleet and employment will expand significantly over the next five years with the acquisition of Airbus A321Neo long-range aircraft from 2019.
"This aircraft type will open up new markets, expand the network and enable a new growth phase for Aer Lingus," the airline said.
Aer Lingus chief executive Stephen Kavanagh said the new route will offer great value choices to the airline's customers and further enhance the country's trade and business links with the US.
"Since joining International Airlines Group some two years ago we have grown and strengthened our Dublin Gateway to North America and we look forward to continuing this development in the years to come," he said.
