First class upgrade Doncaster to London

[johnnychips]

My friend bought a return off-peak ticket from Doncaster to London, standard class for about £88. How much would it be to upgrade to First Class? He is travelling on Friday at 0947, and coming back Sunday evening. Apparently he has had contradictory answers from National Rail.

Thanks

John

EDIT: Apparently he was told to buy a £252 return, which looks like two single tickets to me, then claim a refund on his original. However I don't think he told them he was coming back on Sunday.

Basically, he can get a £20 upgrade on Sunday, I think. What would it cost to upgrade his outward leg, and does this have to be done at the ticket office, or can it be done on the train.

There are different ways the excess fare may be calculated.

Sorry, no calculations, as I did them based on an Off Peak Return, but then I realised it was a Super Off Peak Return... but you can find the fares on www.brfares.com

Really appreciate your quick reply. Not as simple as I thought it might be. I'll advise him to go to the ticket office and see what happens.

Many thanks
