How to book a specific class of ticket, like S or W?

Can someone remind me where the page is on the VS website where you can choose the precise class of ticket you want to book - like L, Y, B, S, Z, K etc.

All I can ever find is options like PE (lowest) and PE (flexible), when I know there is a better page on there for people who want a specific category.

I'm booking from the USA site, fwiw. thanks.

Hello

Once logged into your flying club account, complete the following:

Flying Club (on the left) > Spend Miles > Upgrade/companion flights.

It's the same on the US site.

Thanks!

and to confirm: lowest upgradeable (with miles) from USA is
B in Economy
and S or W in PE?

Yes, that is correct for US originating fares.

Yes, that is correct for US originating fares.

To avoid confusion, an L fare is lowest upgradeable economy for those originating their journey in the UK (generally)

Who is confused

And don't forget you can upgrade from M as well if you're starting in SA, Japan, India or Nigeria. Which obviously makes sense because you wouldn't want to spoil your US or UK customers would you ! ! !
