Singapore Airlines as always had good service. Being a night flight, there wasn't much in terms activity after brunch was served. Singapore airport one of the best hubs, no issue with checkin, immigration or security. At Shanghai airport immigration didn't take long, was hardly any queue, baggage was out within few minutes. Overall a satisfactory trip.
