Hi everyone,
I will be travelling from Euston to Liverpool this Wednesday on an Off Peak Return with a 16-25 railcard (£46.20 - valid during peak as well I believe?).
My question is can I excess the ticket to return from Manchester instead of Liverpool? Is this a case of a zero excess + £10 admin fee?
Thanks

I appreciate the expert advice given on this forum!
There is no excess payable, because the only options are: LM Only (which you don't have) and Any Permitted (which is the ticket you have as the price £46.20 matches that) so as long as you stick to permitted routes you do not need to pay any extra.
Permitted Routes from London Terminals to Liverpool Stations:
- Direct trains from London Euston to Liverpool Lime Street
- Shortest Route: via Milton Keynes, Stafford, Crewe and Runcorn
- Mapped Routes :
LONDON GROUP - LIVERPOOL GROUP:
If the routes were "Not Manchester" and "Any Permitted" then an excess would be required, which would have been half the difference in price.
If Manchester was not on a permitted route then you would be deviating from route, which cannot be excessed and you would then have needed a new ticket from e.g. Crewe to Manchester.
There is no admin fee. The only time an admin fee would apply to a walk-on ticket is if you wanted to get a refund of your ticket, then you would not be able to get one as the admin fee of £10 is greater than the sum of the refund due (65p).
