Talking to the ground engineer from CGK, every time he gets paxed home on duty he has to go Garuda because it's cheaper than QF.
Yes, it may be cheaper to use Garuda but have you considered that every time someone dead-heads or paxes, revenue is potentially displaced, especially when Flight Crew, other than Second Officers, have firm P class bookings? Paxing crew and other staff can prevent the carriage of fare-paying passengers: cost is just one part of the equation.
