On Sunday I need to travel from Oxford to Southampton (Airport). I currently hold a valid return ticket from Hertford - Southampton.
Would it be possible for me to buy an (advance) single from Oxford to Reading, and then use my existing Hertford - Southampton ticket for the rest of the journey from Reading - Southampton?
