I didn't mention the lounge - in SYD VS use AirNz lounge. Food, drinks etc far better than QF lounge, in LHR VS have possibly the best J class lounge in the world. All free, including champagne bar, restaurant, deli counter, games area, beauty salon - it just goes on and on. Staff wait on you, bring drinks and food - seen any of that at BA J class lounge which QF use at LHR. VS have on-board massages, and seats have direct access to aisle - no stepping over aisle seat passengers. Vs actually have a genuine full bar, with bar stools, attendants serving during flight etc. We have even had dinner at the bar when flights are not full, and you can stay in fully flat bed for take-off and landing, wearing VS supplied pj's.
In LAX QF use AA lounge - drinks are charged, free food is very minimal.
In HKG VS lounge is their own, includes restaurant, staff bring drinks and food.
