Norwegian Air International has announced plans to expand its Shannon-New York service from this winter.
The airline began flying from Shannon to the US last July.
It is to increase its New York Stewart International Airport from Shannon to a daily service.
The extra daily flight will start from October 28, 2018.
The news of the move to a daily service further strengthens Shannon's long haul connectivity and its position as a transatlantic gateway.
Declan Power, Head of Aviation Development at Shannon Airport said that 2018 is set to be a "bumper year" for passenger choice on the transatlantic with services from Shannon Airport.
Services will fly from Shannon to New York JFK, New York Stewart International, Newark, Boston, Philadelphia, Providence and Toronto and all of the onward global connections from these airports.
Meanwhile, shares in Norwegian Air continued to rise today, having jumped almost 50% the previous day after Aer Lingus owner IAG said it may offer to buy the company.
Norwegian's Oslo-listed shares closed slightly higher at 265 Norwegian crowns, having earlier reached their highest level in 15 months.
