PE Upgrade Question

Hello ladies and gents.
I'm due to fly man to mco vs73 (747) on July 10th and I've paid virgin to pre book some exit row seats for my GF and myself.
I appreciate that I'm flying in July so it's unlikely...but if I get offered a PE upgrade on checkin, where would I stand with the cash I've already paid?
I paid £80 for the exit row seats and another £40 for some extra legroom seats on the a330 for the way home.
Thanks for any advice, great forum btw... I'm a bit of an Aviation nerd so there's a wealth of information here
