ok, I'm not sure if this is honest or not but its tempting. Due to to be travelling from preston to plymouth. Currently have standard class reservations (open ticket) : 1617 Preston - wolverhampton 1641 wolverhampton - birmingham new street 1807 birmingham new street to plymouth I know the 1807 is going to late as it hasnt even left edinburgh yet. I suspect on getting to new street it will not only be chaos but heaving and my chances of making the reserved seat are going to be slim (middle of carrriage) If I upgraded to first class when I get to preston, will I be able to use delay repay to get my money back? I would not normally afford first class but it seems a decent way to chance getting a comfortable seat with a 10 minute FC reservation.
