I flew with SIA to Malaysia, via Singapore last month, on a 777-200ER out of Manchester.
Having flown KLM last time, SIA was fantastic - good leg room, comfy seat, fantastic IFE, good food, attentive and helpful crew. I knew before i left Man that my bag had not connected with the SIA flight, but i had to go anyway, but the crew were lovely, and low and behold when i got to KL, there was my lonely bag going round on the carousel!!!!
The flight was very busy going out but coming back, i scored an empty row, so i stretched out, the crew fastened my seatbelt round me and off i went to sleep, fantastic!
They really have got a class product and I would not consider flying with anyone else to Malaysia. The shocking service and dreadful planes flown by KLM is never something i would consider again, having flown SIA.
