I give it 6 months - happy to be proven wrong, but I think it's a decision underpinned by complete nonsense.
Of all the international routes VA could have chosen, they picked this one?
What's the logic behind CBR-DPS? Where's the traffic coming from? Is this just a fleet utilisation thing? Are there subsidies involved? Is this a sneaky way to get more seats on the route as an operational backup in the event of another Poo Plane incident?
You'll get some people depart CBR instead of schlepping to SYD/MEL, but you're talking a handful of people every week maximum. Are there domestic and international connections for through pax?
I'd argue Fiji only makes the thrice-weekly Crash-8 work because a) Fiji is a premium holiday destination, and b) there's sufficient through traffic onto the rest of the network.
As for the poor sods on VA, they'll be spending nearly 7 hours on a 737 coughbox, either cramped in economy or wondering what is even remotely "business" about the bog-standard domestic recliner.
The hard product isn't priced much better than QF's (and is largely the same), and the soft product is a complete joke - so what's the incentive to fly VA ahead of the competition?
And don't start me on the lounge beforehand, where they are still too cheap to pay for the flavourings on the crisps.
Also curious that they launched with sale fares and reward seats in Y, but had outrageously overpriced fares with no apparent award availability in J for any of the dates I checked yesterday.
At those fares, I could just fly QF or GA in a lie-flat via the usual ports of SYD/MEL. Heck, I'd rather still go via HKG or SIN as I've done in the past.
As Batik found out, without a network to connect to, cashed-up bogans flying to DPS from CBR are few and far between. If they couldn't make it work with cheapish fares, then I doubt VA will either.
