Last week, the US Department of Transportation stated that the United States and China would allow four flights each week between the two countries. Delta became the first American Airlines to announce the resumption of flights between China and the United States. The Seattle-Shanghai route will be resumed starting June 25, and will operate twice a week. From July, the Seattle-Shanghai route and the Detroit-Shanghai route will be operated. United also said recently that it hopes to resume flights to China in the coming weeks.
Comment: Many times back and forth, finally American Airlines will officially resume the Sino-US route. It is understood that only 75% of business class seats and 60% of economy class seats will be opened on Delta's resumed routes, and will stop at Seoul Incheon Airport in the middle. The United Airlines will resume the San Francisco-Shanghai Pudong route on July 6. Then, the news came out... the ticket seems to be out of order... In this case, the ticket is still hard to get... source
