thanks Nihao!
PER short haul used to operate DPS return twice a week, but that has since been given to AO and PER short haul now operate a CGK (Jakarta) return four times a week (thats what it originally was, it may have gone down to 2 or 3 services a week now?) DPS returns were feral flights. Always full and always crazy, having the extra crew member taken off didn't help either.
Last month, PER short haul operated A330 services to SIN, one leaving pretty much every day, this month PER L/H are doing them and PER S/H have now taken over the A330 services to HKG and NRT on a permanent basis by the look of it.
