Jongar,
Firstly, the A340 is not equipped with the Sky Suites but the usual First seats. The seats do not go fully flat, but instead to about 70 degrees. This allows the all important chance to lie on your side. There are pictures of the seat at
www.airliners.net. Just put in Singapore Airlines and 'cabin views' into the search fields and you can see for yourself. Also of note, the pictures were taken in Adelaide as well. Unfortunately my technological incompetence precludes me from putting a direct link here.
No turn down service is provided. This may have changed (I doubt it) since I flew, but as flying time was only 5hrs 55mins, by the time the full supper service was finished the aircraft was almost crossing the Australian coast. I was given a pair of First Class pyjamas and an amenity kit, but this was due to my very good rapport with the CSD, along with my quite detailed and critical analysis of the flight to SIN.
The flight offers supper and continental breakfast. By the way, be prepared for a very speedy exit through immigration. On my flight I was the only person in First and literally there was about two minutes between my arrival in the immigration hall and the arrival of the Raffles passengers.
If you don't have any luck at
www.airliners.net, just let me know and I will provide as much detail as I can.
