It's under an hour of flight-time; you go up, don't think you even hit normal cruising altitude before you're coming down again.
Depending on which plane they use, whether the older or newer 738s, you may not have a screen. All standard recliners, ok in comfort terms. Not bad per se, but probably could do with a bit more elbow grease in the cleaning, even the new planes.
Food is nothing special, though more than sufficient for such a short flight, and okay taste-wise (but better if satay is one of the options, have had that twice on SG-KL flt!); alcohol won't be made available (get your drinks at the lounge pre-flight!).
Crew are always friendly! ^
