From the Cent member point of view how's Virgin J compare to Qantas J?
Since all my travel is on points and in premium classes it doesn't make a LOT of difference. I have no status on QF and no way to earn it, but do have CX status from Amex, which helps with QF seating.
VA status means little, except a few car rental addons, and maybe faster phone response time. I DO like the premium entry in SYD, which makes the airport experience a bit more bearable, but that is avail to all premium fare travellers, too.
VA Plat gets 4 upgrades on paid fares, and I have a comp upgrade which I never use, as it's always on points, Europcar Privilege, Secure sentinal (I don't bother), Family pooling (QF doesn't offer this). Other benefits are already avail for Centurion members.
Onboard, VA meals vary, but so do QF meals. I like the tablets on VA, but must take own phones to hear the movie. Main thing I like is VA has a good range of snacks which you can request at any time, in J - cheese, nuts, chips, chocs, etc. They allow you to choose from the menu for sale, if the normal meal is unappealling.
Boarding - VA now offers priority boarding in most places, so no diff to QF.
Otherwise, it's all domestic, and nothing special.
