Yes, I'm certain and this was confirmed to me by the Virgin call centre operator as well (who was also surpised how cheap it was working out).
In fact my employer booked myself and a colleague on PE at £12 each for the return leg. Outbound it was around £200 each which we didn't go for, but as the return is overnight my employer added it so we could sleep - and hence the start of these troubles getting my wife sorted.
I'm still waiting for a response to my email sent on Monday evening so I reckon it is in the "wait a week and then reply saying nothiing we can do" pile.
