Not sure. Check United. I understand United us selling July tickets to Peking. Sounds like United has an international game plan in SFO starting on July Wherever you go have a safe and pleasant trip. It is time to fly.
Right now it's best to check on the airline website for the up to date information. Many destinations have restrictions and mandatory quarantine measures. United airlines only offer currently to international from SFO is Tokyo Narita, Sydney, and Frankfurt with proper documentation before travels.
Flight to which country? Mostly evacuation flights only operate in jun 2020. If flights starts to the country You want to travel then it will be available in google flights search.
