Excuse me if I’ve missed the sarcasm, but, otherwise, your taking the piss, right ?
I'm simply stating what I saw when I arrived, J* crew checking out as I was checking in. I was on holiday so the cost was out of my own pocket hence HI Express rather than 5*. Most of the cabin crew were Asian, I think the boss was Australian. Cabin crew sharing rooms is very common in this part of the world especially with low cost airlines. Bogans demand cheap tickets and costs need to be cut where ever they can. For Australians, Bali is a lower end leisure destination which is relatively close and therefore won't support a premium airline. For Europeans and Americans it's a luxury destination and can easily attract premium passengers willing to pay a bit more for a comfortable 20 hour journey.
Similarly, for Australians Spain is exotic whereas for Brits it's low end package deals.
