OAKLAND — Oakland International Airport has kept up the momentum of its growing passenger count into 2017.

Airport officials said Thursday that total passenger traffic reached 908,898 for the month of January, up 7.8 percent from the same period last year, thanks to a record number of destinations and increased flight routes.

The increase marks the 38th consecutive month of year-over-year passenger traffic growth for the airport, which officials partly attribute to Norwegian Air Shuttle, which has fueled international traffic to and from Oakland. The airline began service to London-Gatwick last year and this winter increased its flights to Stockholm.

The airline has more plans for growth at Oakland. It will launch its route from Oakland to Copenhagen in March and Barcelona in June.

“We are very pleased to have had such a strong start to 2017, and that we’ve been able to maintain the momentum experienced in 2016,” said airport director Bryant Francis in a news release from the Port of Oakland. “More than a half dozen new routes are recently underway or are soon to begin.”

Francis indicated that the airport is also focused on growing its number of flights to east coast and midwest cities that are “under-served” from the East Bay but in high demand.

This year, the airport has several new and expanded routes slated to begin, including flights to Copenhagen, Baltimore, Detroit, Newark/New York, Barcelona, and more routes to London-Gatwick. New service began this month to Puerto Vallarta and Los Cabos, Mexico, Southwest’s first international flights from the Bay Area.

The Oakland airport has been boosted by an increase in international and domestic travel to the East Bay. The airport has been working on a $35 million expansion to its international arrivals building that will double international flight capacity and recently unveiled a new passenger lounge to serve its growing number of travelers. There is also the ongoing $200 million renovation of Terminal 1, which was started in 2008 to update and modernize the airport.
