SIN-HKT-SIN. Both flights were serviced by a A320. The interior on both planes were old and scuffed. The seats were ok but not overly comfortable. Cabin temperature on the outbound flight was too cold. There was no personal inflight entertainment system though an overhead entertainment system played the same episode of the same show on both flights. Complimentary meals and drinks provided on both flights though the quality of the food and range was slightly worse than that on Singapore Airlines. Even though my return flight was a morning flight Silk Air decided to serve a curry where a breakfast meal would have been more appropriate. Outbound flight was full of Australians yelling at the top of their voices and walking to the front of the plane in an attempt to be the first to order a "cold one". The crew worked well under these difficult conditions. The service is very good. Nevertheless the flight attendants remained composed managed disrespectful passengers well and always kept a smile on their face.
