Been a VA PLT and QF Gold for a few years - last year decided to chase PLT on both and achieved it earlier this year (thanks but no thanks to significant domestic work travel). Here's my list:
Lounges: If you are after good selection of food/beverages - Qantas wins hands down.
But I personally prefer VA for lighting in the lounge, coffee, service, dedicated security lanes (Mel/Syd) - and lastly may be I am use to those lounges after years of using them.
Flying internationally, Qantas has the edge again - but the house lounge which VA is using in Melbourne after AirNZ split is awesome too (when not full)
Get Home Early: VA wins here without a competition. Not sure if this is important for other people - but the nature of my travel demands flexibility on return flights .
In Virgin I can pick Elevate which is cheaper than flex (VA or QF) - but still show up at lounge early and request to fly early. Have had success with this almost 99% of time. Also the rest 1% - you can use one of the complimentary J upgrades if a seat is available.
With Qantas - I have struggled even with Flex - forget about flying early on a cheaper fare (especially when I was gold - PLT didnt improve this much)
Family Benefits and Pooling - Virgin here - Easy to gift gold to the spouse - and also potential to make her fly crazy routes when she's flying individually to get more status credits when required.
Maintaining status & Velocity Points: Its not only easy to maintain VA PLT based on total no of required points - you also get more credits and a heaps more velocity points (800 points in QF vs ~3500 on VA for equivalent price) when flying domestically.
Upgrades: Slight edge to VA when flying domestic (4 complimentary) or to LAX (as they are not as full as QF flights generally)
International: VA is getting better - but QF is far more connected. So if my work involved a lot of international travel - I would pick and stick with Qantas.
Crew & Premium Boarding: As others have pointed out - prefer VA here.
Redemptions: Have had better luck with VA (but only with economy)
Call Centre: Had awesome experience with VA - never paid a single penny for changes/cancellations etc , always accomodating. QF always tries to stick you with a few hundred dollar charge (I might be biased as most of this negative experience is from when I was gold) - havent had to do any changes on calls since I became platinum.
IT Systems: From mobile apps to website - QF is far far better experience. VA has problems still when I am using chrome to pre-fill cc details to book , so I have to get the card every time when I need to book. As an upside, now I remember my amex card number. Here's another example of VA's coughpy website:
Virgin Australia's Website Doesn't Work. A while back, I also had pricing errors on VA website (where the total was incorrect)
I guess we are lucky to have two awesome airlines - these are nitpickings! Both are awesome, but I have come to prefer:
- VA for heavy domestic travel & occasional international flights.
- QF for heavy international travel
