Affiliate disclosure

RailPassMath currently uses no affiliate links and shows no ads. Every link on this site goes straight to the official operator or source page, and we earn nothing when you click it or buy something.

If that ever changes

We may later add affiliate links, for example to tour or activity booking sites. Before we do, we will update this page, naming each partner, and follow these rules:

• Recommendations come first. The calculator and the guides recommend the cheapest or most sensible option for your trip, whether or not anyone pays us. Rail passes and tickets bought from the railways themselves would still earn us nothing.
• Clearly labelled. Any page with affiliate links would carry a short disclosure near the top, and the links would be marked rel="sponsored nofollow".
• Official prices. When we quote a price, it comes from the official operator, not from a partner's page.
