Can I ask you experts for your advice please 
I am travelling UC next month and my friend travelling with me has a PE ticket brought through Airmiles (i.e. not Virgin miles).
She is looking to try her luck at upgrading at the aiport on the day of departure using her Virgin flying club miles - do you think she's in with a chance and how much money will she have to pay?
Thanks
Clare
