OAKLAND — Oakland International Airport is once again adding to its list of nonstop flights out of the East Bay.

Hawaiian Airlines is expanding its direct service between Oakland and the Hawaiian islands, adding a year-round nonstop daily flight from Oakland to Kaua‘i beginning in April 2018.

It’s part of a West Coast expansion by Hawaiian Airlines, which is adding a fleet of single-aisle A321neo aircrafts to provide year-round daily flights out of Oakland as well as Portland, Oregon, and Los Angeles.

Starting April 12, flights will leave Oakland for Lihu’e, Kaua’i, daily at 8:30 a.m. Flights from Lihu’e to Oakland will depart daily at 12:40 p.m. — arriving in Oakland at around 8:55 p.m. each evening.

Hawaiian has been operating a seasonal flight service running several times per week to Kaua‘i in the summer that is scheduled to end this year on Sept. 4. It will resume in April as a daily flight, according to Hawaiian Airlines.

The Oakland airport has flight service to four Hawaiian islands. The expansion of Hawaiian Airlines’ service marks the latest addition to the airport’s growing roster of nonstop flights. The airport has seen record numbers of passengers and flights in the past year, thanks to a slew of new international and domestic flights.

Among the most recent additions are direct flights by Norwegian to Paris, France, and Rome, Italy.
