no idea what its based on, just saw the headline and laughed. I assume its something like an average family of 20 doing a world tour!
As for if VH will add it or not I dont think anyone knows yet. I read on the v-flyer forum a few weeks ago something like that either
virgin atlantic or VH (cant remember which!) DOES have in its T&Cs that it can go back to passengers and ask for more if only a deposit has been paid.
Guess we'll have to wait and see - im in the same position as you it seems!
