I flew SQ286 on Monday in Business. Airconditioning was not working when we boarded the aircraft - it was very hot. It was a few hours into the flight before conditions became comfortable. No cool air was available through the vents. At one stage, the captain came to check on what was happening and reduced cabin temperature by a further 2˚C.

I find the SQ spacebed is more comfortable than what is offered on this aircraft.

Departure of flight was also delayed by one hour due to late arrival of inbound aircraft - although not informed of this in the lounge until scheduled time of boarding.

Another observation was that the F Cabin was empty.
