The U.S. Department of Transportation has given the final go ahead for Delta Air Lines' new nonstop service between Seattle and Tokyo International Airport (a.k.a Haneda Airport).
The new service starts June 1, 2013.
Haneda is the preferred Tokyo airport for a lot of businessmen owing to its proximity to the city's central business district.
Seattle's disadvantage as the only large West Coast city currently without a nonstop service to Haneda will disappear June 1.
The Haneda flight will complement Delta's existing nonstop flight between Seattle and Tokyo-Narita, which the airline plans to upgrade to Boeing 747-400 service on June 1.
The airline's Boeing 747-400 fleet was recently done up with new interiors featuring full flat-bed seats in BusinessElite, Economy Comfort seating and in-flight entertainment in every seat.
Delta has been growing Seattle as a major hub for travel to Asia.
Beside the Haneda flight, Delta plans to inaugurate a new service to Shanghai on June 17.
The airline already operates flights to Beijing, Tokyo-Narita and Osaka, Japan from Seattle.
