I can't locate an answer to this query on here of V-Flyer but apologies if I have missed it!

I have just qualified as Flying Club Gold and have booked return flights from London to Sydney on Singapore with my partner. With my Flying Club Gold UI think I can

a. check in at the business class desks of Singapore
b. use the Silver Kris lounge
c. priority board

I presume as my partner and I are travelling together these benefits are extended to him as my one guest? Does this mean we can use the Silver Kris lounge in Singapore or are we in the Premier Lounge? Can we use the VS Clubhouse in London instead of the Silver Kris lounge?

Thanks for any help!
