Aviation U.S. airlines get permission to operate in daytime at Tokyo Haneda By Robert Silk / February 18, 2016 Share 1 -- U.S. airlines will be able to fly to Tokyo’s Haneda Airport during the daytime under an amendment to the U.S.-Japan air transport agreement. The daytime flights are expected to begin as early as this fall, said the U.S. Embassy in Tokyo announced. Haneda is Japan’s largest airport and is also located more than 30 miles closer to downtown Tokyo than its primary alternative, Narita International Airport. But under the current U.S.-Japan aviation agreement, U.S. carriers are allotted a total of just four daily arrivals and departures into Haneda, all of them restricted to nighttime hours. The amended agreement would increase the number of allotments, called slot pairs, to six daily, with five to be operated during the daytime and one to be operated at night. American Airlines, which began daily service between Los Angeles and Haneda last week, reacted quickly to the news Thursday. The flight, which currently arrives in Tokyo at 11 p.m. and departs at 1:30 a.m., will be shifted to the daytime this fall.“Earlier arrival times in the U.S. and Japan will allow for more convenient connections to American’s robust network out of LAX,” the carrier said. United, which flies from San Francisco to Haneda, also commended the agreement.
