So basically, I am a UK resident, and I managed to get a free 7 day pass with the scheme run by the EU. I have decided that I want to purchase an additional pass to get some more travel days, probably another 7 day pass.
However, since I do a lot of rail travel within the UK, I have noticed that I can purchase a 10 day pass for about £60 more than the 7 day pass - since I will have 2 passes, and I am currently only using one outbound and one inbound journey on my pass, I will have an outbound and an inbound day of travel left over, so I was wondering if I could then use these two days to travel around the UK, most likely starting and ending these trips at the same station (which is most likely Reading or Oxford, which are arguably close to airports) but if necessary I could say use it on a very circuitous route from Reading to Heathrow and then purchase a ticket to get back to Reading
Essentially, the question is does the outbound/inbound journey have to be a journey on the fastest route to the airport/eurostar/ferry, could it be a circuitous route to the airport/eurostar/ferry, or can it be a circuitous route starting/finishing anywhere?
