I selected Shenzhen Airlines (Shenzhen 9102) for my domestic flight primarily because it is a member of the Star Alliance group of airlines, complimentary lounge access, priority boarding, non-stop service on the 3hour 40-minute flight, past experience with the airline, and price. The Airbus A330 had good legroom, and my aisle seat was very comfortable. The onboard service was attentive, polite and friendly. Being a gold member, I was checked-in quickly in the Business Class line. Departure was delayed by about 10 minutes, but we still arrived at SZX airport on time.
