PE upgrade after booking

I have a trip with VS booked to New York in November in Y. When I 'amend booking', the option is there to upgrade to PE either on the outbound leg or for the whole journey. Is it possible to upgrade the inbound only?

Best bet would be to give FC a call, they will be able to advise best and give you a price etc.

Cheers Neil. I will talk to my friend first and try and persuade her!!
