I just arrived back in Sydney after trying the VS/VA trip from London through HK. I thought I'd share my experience for anyone considering this route.
I usually do my Europe flying on Singapore or Etihad but I was curious.
I am Velocity Platinum and I flew Economy.
I'm not sure if Velocity Plat members can use the drive thru check in at Heathrow, but I decided not to risk it.
I used the VS Upper Class check in within the terminal with no problems. No waiting.
I asked the staff if I could use velocity points to upgrade and the answer was 'Yes, but you need to call Velocity".
I called Velocity and the answer was 'no'.
My velocity number and status didn't appear on either of my boarding passes, but the check in staff did write "velocity plat" on my boarding pass.
I had to show my digital velocity card showing the expiry date to enter the lounge, which was a major pain because my phone battery had died. There seems to be a very clear rule, no proof of status = no entry.
I'd never experienced it, so the Virgin Clubhouse at LHR was the main reason I booked this route and I wasn't disappointed. It has to be up there with the best I've ever experienced. I've heard comparisons with QF First in Sydney which I've never been to -the best I've been to is the LAX Star Alliance lounge by Air NZ - and the clubhouse probably wins.
Boarding the flight was pain free - I boarded through the Upper Class line with no problems.
The flight was full but comfortable. The seat was fine and the food options and entertainment weren't great. All in all an ok flight with the highlight being we arrived 90 mins early, but I would probably go with Singapore over VS and Etihad for the hard product.
I had forgotten how much I hate Hong Kong airport. It's a maze of travellators and inter-terminal trains with no clear signage. It took me about 45 minutes to work out where the Hong Kong Airlines lounge was and how to get there (go through transfer security and head for gate 209, look behind you and up stairs and there she is).
The HK airlines lounge was nice, not very busy when I arrived but very busy by the time I left.
Top tip: If you're hoping to take a shower in the lunge you need to book one with the front desk and I'd recommend doing that as soon as you arrive. I decided to eat first which was a mistake. You can't book a time for a shower, you are given a buzzer when one becomes available, and they don't or can't tell you when that's likely to be. I waited 90 minutes for my shower.
When I boarded the VA flight to Sydney there was confusion over my boarding pass because it had been issued by VS. After a few minutes of frantic phone calls they just gave me back my original boarding pass and I boarded without any problems.
I was greeted in my seat by the head purser and received recognition for being a platinum member by way of a menu that everyone else received just before service started. A small gesture I guess, but I remember when Etihad used to hand out noise cancelling headphones to Vel Plat members!
The VA food and entertainment was worse than the VS flight.
In all - the Clubhouse was the highlight and the rest was pretty average. I'm doing the return journey in a few weeks and the only thing I'm looking forward to is the 'Etihad' lounge in Sydney and the revivals lounge in London.
As a Vel Plat who often travels in economy for these long flights my assessment is:
Best for comfort: Singapore Airlines
Best for Service: Singapore Airlines
Best food and drink: Singapore Airlines/Etihad
Best entertainment: Etihad - because they have live sports
Best lounges: Etihad wins because I believe the most important lounge is the one you use in transit. Second would be VA/VS and last would be Singapore because of the shambles of a lounge in SIN.
