probably obvious question re upgrading S or W to G

I know I should know the answer (and it's probbaly a really obvious answer like 'phone FC') to this but am suffering from brain ache.

I'm looking to use miles to upgrade from PE to UC - 40k miles

I know I need to be in S or W (S preferable to save a few pennies as its £ 1280 compared to £ 1975 for LHR to NYC for when I want to travel)

(If there was a sale I'd probbaly go for a Z but no sale at the moment)

I know I also need G availability but where in the booking engine process does this show up?

I got as far as the page to enter my CC details but obviously don't want to fork out if there are no G's (and yes I was logged in and used the option to select an S fare).

If you click on spend miles and search for an Upper class fare it will return dates that they are available, at least thats what I've been doing to figure out whats dates are available

As Bear says, it's doing a dummy booking for a reward flight and then using this link to book.

Bear in mind though that if there is a limited amount of availability you may well have blocked the one remaining seat by your own request. In the past (and it may well still be happening) if one did a dummy booking the website "held" that request for a certain amount of time. I can still remember looking for Zs one Sunday afternoon for a variety of flights to either MCO or JFK. All that was available were Ds. On Monday the Zs were back with a vengeance! Obviously the world and his wife were cruising that afternoon and doing dummy bookings!

Cruising HL, you spend too much time in San Francisco :0 .

Currently, the VS Web site doesn't let you beyond the availability page in some browsers ... but even if you do end up in this situation where you are 'holding' a reservation, if you call FC at the same time I've found before that logging out of your FC account while talking makes the G reappear right away for the FC staff member you are talking to.

You can call FC and get them to hold a G for 24/48hrs for you. That way you can make your booking online if you so desire and then call back to do the actual upgrade, although I find it much easier just to do the whole booking over the phone.

Thanks.

Just had a fluffy brain last night (and no it was not drink induced!)
