We have coordinated with the ticket office according to your request, and found that if you book a flight from A to B at 9:00 am on 20 15 1 20th, you will stop at airport C, but there is no direct flight from airport C to San Francisco. This means that if you book a return flight from D to San Francisco, the first flight will stop at D.
Therefore, we chose flight 123, which stops at D. This is the earliest connection with the previous flight, and the stopover time is more than 3 hours. You can rest in the reserved lounge.
Thank you for your understanding.
