OAKLAND — Bay Area residents have yet another nonstop flight to Europe on the horizon.

Oakland International Airport and low-cost airline Norwegian will launch a nonstop route to Rome from Oakland in early 2018, the latest in its growing collection of international flights.

The flights will begin Feb. 6, 2018, with a twice-weekly service between Oakland and Rome. Fares will start at $229 one-way (including taxes) for “economy” tickets, but “premium” fares will run passengers $719 or more for a one-way trip. Premium tickets give passengers allowances for extra luggage, “fast track” security, priority boarding, sleeper seats and all meals and drinks, according to the airline.

The route to Rome joins other nonstop routes that Norwegian has launched between Oakland and Europe, including a direct flight to Barcelona that begins June 7, and flights that have been running to London, Oslo, Stockholm and Copenhagen.

Norwegian said it will launch at least 25 routes out of U.S. cities this year, including 12 transatlantic routes.

Thomas Ramdahl, Norwegian’s chief commercial officer, promised in a news release that the airline will “soon offer more transatlantic routes than any other airline in the world.”

The young airline transported 26 million passengers in 2015 and currently operates more than 400 routes to about 130 destinations in Europe, North Africa, the Middle East, Thailand, the Caribbean and the United States.

The Oakland airport has seen record numbers of passengers and flights in the past year. It recently reported that it served 1,008,886 airline passengers for the month of March, a 4.8 percent increase over March 2016. It is the first time passenger traffic at the airport surpassed 1 million visitors for the month of March in a decade.

The airport attributes that growth mostly to its surge in international flights. International operations increased by 73 percent over the same period last year. In addition to Norwegian’s flights to Europe, Southwest Airlines began its first international routes — to Los Cabos and Puerto Vallarta, Mexico — from Oakland in February.
