A discount is not automatic. Discounted fares are only charged to a personalised card that already carries your discount group. With an ordinary or unregistered card you pay the full price, whatever you qualify for.
Who qualifies for a discount, and who travels free, is set by rules this page states but cannot check. If your case sits near a line — an age, an address, a certificate — the operator decides, not this page.
Prices change. The date at the foot of this page is when they were last checked against the operator’s own page; if it looks old, check there before you buy.
This page does arithmetic on published prices. It is not connected to your card, it cannot see your balance or your travel, and nothing you choose here is saved or sent anywhere.
