In my limited sample of AirAsia flights, they keep the cabin temperate at arctic. I was freezing on my red eye HND-KUL. Only had a lightweight sarong as a blanket which barely helped and I was too cheap to buy a blanket. I generally like it cold but this was ridiculous

I vaguely recall some MH flights being rather chilly which matches up my general experience with AC temperatures in Malaysia. Felt kind of silly when I started taking a jacket with me for general sightseeing even on hot days but was absolutely necessary to not freeze indoors!
