Hawaiian Airlines will add a second nonstop route between Hawaii and Tokyo’s Haneda International Airport.

In April, Hawaiian said that if the U.S. Department of Transportation approves the routes, new flights to Haneda International Airport would be available from Honolulu Airport four times per week and Kona International Airport three times weekly.

U.S. Sen. Brian Schatz said he was informed of the U.S. Department of Transportation’s decision to award the route to Hawaiian this morning.

He said today’s announcement is the result of an agreement the U.S. finalized with Japan earlier this year to expand the total number of flights between Haneda and the U.S. from 4 routes to 6 routes.

“It is important to keep in mind there are five more routes up for competition, and I will continue to strongly advocate for Hawaiian Airlines in their effort to secure more direct flights from Tokyo to Hawaii. Hawaiian has a proven record of success in the Tokyo market and there continues to be tremendous demand to fly into Hawaii.”

State officials last month said the move was expected to bring more than $100 million to the state each year.

The Hawaii Department of Transportation said just one new international flight is expected to generate about $113 million in spending annually and boost the state’s tax revenue to around $14 million each year.

Hawaiian has one of the four slots and flies to Honolulu daily. United has one and flies to San Francisco with it. The remaining two are used by American and Delta, both to serve LAX.
