STEWART AIRPORT – A spokesman for Norwegian Air Shuttle said Wednesday that introductory fares for its new service to Europe from Stewart International Airport will start at $69 one-way.

Average round-trip fares in general will run between $300 and $350, including taxes, but not including other common airline fees.

“(We) will simply bring the cheapest trans-Atlantic fares Americans have ever seen …,’’ said Anders Lindstrom, Norwegian’s U.S. director of communications.

The carrier plans to launch the new service in mid-2017, shortly after it takes delivery of the aircraft that will be based at Stewart, two Boeing 737 Maxes, a single-aisle plane that seats 189 passengers.

Norwegian, which employs about 500 people at its bases at John F. Kennedy and Fort Lauderdale, will hire 75 pilots and cabin crew members for the Stewart operation.

Exact routes, frequencies and fares will be announced next year, but Lindstrom said nonstop flights to Cork, Ireland, will be among the first ones offered.

“We already offer more trans-Atlantic routes than any other European airline, and within a few years, we will offer more … than any other airline,’’ he said.

Allyson Crawford of Kingston, a career travel industry professional, described Norwegian as a well-established airline with “a great reputation” and urged the Hudson Valley community to support its plans.

For example, she recommended a campaign to “wow” prospective passengers about how easy it is to use Stewart and observed that superior ground transportation should be in place not only between the airport and New York City but also Albany.

“It’s exciting that an airline is finally seeing the potential for international flights at Stewart,’’ said Crawford, a native of Scotland. “I’m already thinking about some long weekends in Europe.”
