Apologies if this has been asked and answered previously - the fare guide doesn't seem to cover it, and I couldn't find any directly relevant threads from a search. I am travelling from Derby to London on Thursday, and have a standard class anytime return ticket. It looks like I might be taking a slightly later train on the outward leg of my journey, on which an off peak ticket would be valid. I am not yet sure what time I will make my return journey - it may be during the afternoon peak period (off peak returns not valid).
The first class off peak return is cheaper than the standard open return, so I understand that I could excess to this ticket for no extra fee. If I did so, and then had to travel back during the afternoon peak, would I still be able to use the original ticket (in standard class, of course)? Or alternatively, am I able to excess the outward and return legs from standard to first class independently of each other (in which case I could decide whether to do so immediately before travel)?
