The Bali example is a good one. QF commenced DPS services in the mid 70s taking over from Pan Am after their disastrous 1st into the Pacific add campaign.
There were 2x B707 services per week. Each B707 was configured at 20/120. Garuda ran DC8 50s at roughly the same configuration. So about 600 pax either way/week.
Looking at the flights by say Dec 2019 its easy to see why Bali went the way it did.
The crew got 3 or 4 day slips at the Hotel Bali Beach. That was pretty cruisy as well.
