United Airlines has asked the U.S. Department of Transportation for the green light to keep flying customers from its San Francisco hub to Haneda Airport in Tokyo.

The airline is also seeking approval to offer service from its hub at Newark Liberty International Airport in New Jersey.

Tokyo’s Haneda Airport has been handling more international traffic as of late – traffic that traditionally went to the city’s more known global hub, Narita International Airport, located just east of the city of Tokyo.

Per United,

“United’s proposed service will connect two centers of global commerce and culture with Tokyo’s close-in airport and offer customers more options for travel between the U.S. and Japan,” said Steve Morrissey, United’s vice president of regulatory and policy in a statement. “More than 150,000 customers from large and small communities across the U.S. have benefitted from United’s San Francisco-Haneda service. We hope the DOT reaffirms its earlier decision that this route provides numerous consumer and competitive benefits.”

According to a United Airlines press release, the U.S. Department of Transportation and the Japanese government have renewed an agreement that enables U.S. airlines to fly routes to and from Haneda Airport.

As for the company’s Newark location, it said it operates flights to four areas in the Asia-Pacific region – which is greater than any other airline in the vicinity of New York City.
