Thank you for your query.
The Day Pass for the Half Fare Travelcard can only be purchased with a Half Fare travelcard. Point-to-point tickets, Supersaver tickets or Supersaver Day Passes can be purchased with a Half-Fare travelcard as well as without any discount.
You can enter whether you have a discount or not under “Discount Cards”.
