What is the most convenient way to get from Dalian to Chicago?

The most convenient way from Dalian to Chicago is:

1, Dalian to Tokyo, JL798.

2.JL798 goes directly to Chicago, USA. Do a good job of nucleic acid in Dalian Friendship Hospital, color printing is effective, arrive at the airport two hours in advance, and queue up for exit health declaration first. The line was long, but there was only one international plane that day. Transfer in Tokyo: Passengers arriving in Tokyo get off first and then transfer. But there is plenty of time to buy Japanese snacks and skin care products. Luxury goods and Starbucks are closed. When SFO entered the customs, it was changed. When I checked in, my sister told me that I could change to an earlier flight to Chicago.
