I want to travel from Sittingbourne to Bletchley and back, going one way via Bedford and returning via the WCML to Euston. The only ticket I can get to Bletchley seems to be via the WCML, a Off Peak Return, Restriction JK, with BoJ permitted for £30.35 with a railcard. However if I make the journey to Fenny Stratford instead I am offered itineraries both ways for the same fare and same restrictions and BoJ permitted. Presumably then I could buy this ticket and break my journey at Bletchley. I am aware of the time restrictions that are in place for the offered ticket.
