Between July and November Virgin Australia is selling Los Angeles – Bali (via Brisbane or Sydney) for $568 roundtrip.
The fare is widely available, and should be bookable on most travel sites:
Here’s a sample itinerary:
It’s a Virgin Australia ‘Q fare’ which earns full elite qualifying miles and 50% redeemable miles when crediting to Delta. It earns 20% flown miles when crediting to Virgin America (which is better than it sounds since Virgin America points are somewhat deflated, I think of 1 Virgin America point as similar to 2 airline miles, in fact business class only earns 80% of flown miles).
