Your Split Ticket will be made up from a combination of ticket types to get you the best possible deal (for example, Advanced, Anytime, Off-Peak). Each individual ticket will have its own restrictions (including flexibility of times, refunds, etc).
How do I find out about my specific tickets?
Just tap the ‘Ticket conditions’ link on the ‘Split Ticket details’ screen to check the flexibility of each ticket. Generally speaking, your journey will only be as flexible as your least flexible ticket.
