United Airlines says it will increase service to China from two to four weekly flights from San Francisco to Shanghai’s Pudong International Airport. The service flies via Seoul’s Incheon International Airport.

Starting from 4 September, United will operate four weekly flights with Boeing 777-300ER aircraft from San Francisco to Shanghai on Wednesdays, Fridays, Saturdays and Sundays. Customers travelling from Shanghai will return to San Francisco on Mondays, Thursdays, Saturdays and Sundays.

“United has served mainland China for more than three decades, and we look forward to continuing to connect customers travelling between the US and Shanghai with two additional flights beginning in September,” said  United’s vice president of international network and alliances, Patrick Quayle.

In July, the airline began operating twice-weekly service between San Francisco and Shanghai via Seoul. United was the largest US carrier serving China before suspending service in February due to Covid-19. In 2019, it operated five daily flights between Shanghai and its hubs in San Francisco, Los Angeles, Chicago and New York/Newark.
