Upgrade bid BGI - LHR

I am currently booked PE on my return trip to the UK in September so around a month ago I put an upgrade bid in for UC for £580, with the lowest at £500… I logged in today as thought I would increase it but now it’s saying no upgrade bid is available, and all the remaining seats in UC are blocked out….doesn’t anyone have any idea what could have happened? Should I give VS a call ?
Thanks in advance

What date is your flight? UC on this route is often full so I’d imagine it’s just sold out.

Just double checked and it’s 12th October, but expert flyer shows at least 18 empty seats

If you do a dummy booking it’s only showing 9 available seats, not to say they haven’t been sold and just not allocated though

This happened to us on a recent trip to NYC. Even though it stated that we could no longer bid for an upgrade the system knew that we already had. A couple of days before our expected PE flight £500 came out my credit card and i was informed that i had been successful in my bid. Make sure that your payment details are in the VA system because if they cant withdraw it then you dont get the upgrade AND they wont contact you to get the payment.

Thanks everyone…I will just keep my fingers crossed I get lucky !
