The info on the previous page suggests this flight is daily, not 3x weekly. Unless you’re referring to the adl-cns connection mentioned in some posts?No doubt, but how is VA going to cover the cost of operating this flight with fares like that, and very low J fares (QF charge more for SYD-MEL); let alone make a profit. 3x weekly pretty much rules out any business pax.
And while their J fares might be lower than some QF J syd-Mel flights, it’s not a fair comparison to look at the cheapest J with VA on this route with an expensive (almost sold out) fare on qf. Looking at syd-mel, qf J can be had for $1524 (just searching early next year), which is still less than the $2300 for VA on this route quoted up-thread.
