For this particular route, OOL-DPS outbound, the biz fare is a value proposition for AFFers if you come prepared because - in order of importance - the fare includes:
- A very good chance you will actually get to your destination. Around the scheduled time. And your baggage.
- Someone to answer the phone if something does go wrong. Customers not treated like dirt
- A recliner seat with legroom, adequate for a daytime flight
- Smooth passage through the airport with priority lines
- Lounge
- Free internet onboard
- PDBs, food & wine onboard
- Reserved biz class toilet onboard between 8 people
And the bits it doesn't include, those you can bring yourself
- Blanket, pillow, whatever - better than what the airline would have supplied anyway
- Your own devices with better entertainment etc than what the airline would have supplied anyway
- By the way, today's aircraft does have power points oops the crew pointed them out
Also this fare is a reasonable outlay to get out of Australia to somewhere where you can start an overseas trip. Tickets and awards to Europe being much more favourable ex Indonesia or from anywhere in Asia.
But coming back DPS-OOL, BNE, SYD etc? That's a different story, no joy in sitting up all night on the VA biz fare.
