19. Using a combination of tickets
You may use two or more tickets for one journey as long as together they cover the entire journey and one of the following applies:
(a) they are both Zonal Tickets unless special conditions prohibit their use in this way. The Ticket Seller will, if you ask, advise you whether you can use a Zonal Ticket in combination with another ticket.
(b) the train you are in calls at a station where you change from one ticket to another; or
(c) one of the tickets is a Season Ticket (which for this purpose does not include Season Tickets or travel passes issued on behalf of a passenger transport executive or local authority) or a leisure travel pass, and the other ticket(s) is/ are not.
In this instance is a journey;
1) your total journey using a combination of tickets including a change of trains if necessary
2) the journey taken on one train whereby leaving the train to change to another ends your journey using a combination of tickets ?
In particular I want to know can I complete (for instance) a Navigation Road - Milton Keynes journey using a Navigation Road - Stockport 7DS and a Stockport - Coventry and Rugby - MK normal tickets, taking advantage of BoJ of the SOR on the outward portion of Stockport - Rugby?
I think it is permitted - my journey is Nav Road to MK.
I am unsure whether or not onboard staff will think that.
What are your thoughts please?
