Japanese and Chinese air carriers began operating flights Saturday between Haneda airport in Tokyo and Hongqiao airport in Shanghai.
The new service is aimed at providing faster access to the downtown areas of the two commercial capitals than is possible by using Narita and Pudong airports.
Japan Airlines, All Nippon Airways, China Eastern Airlines and Shanghai Airlines will each make one round-trip flight per day on the route.
Hongqiao airport is used for domestic flights and is closer to the center of Shanghai than Pudong International Airport, which normally serves international flights.
Haneda is also closer to central Tokyo than Narita International Airport in Chiba Prefecture.
Flights to Hongqiao and Gimpo are technically operated as charter flights.
