Prices explained

Prices explained

At Rail Europe we believe in price transparency. We use real data from Rail Europe searches to estimate the cheapest fares you should be able to find for your journey.

The cheapest price is the lowest fare we've ever found for this journey. These prices can usually be found by searching when booking opens but they vary due to availability, which depends on factors like the day of the week or time of year.

More popular journeys include 30 day advance and 7 day advance prices. These are updated every two weeks using prices we've found by searching exactly 7 or 30 days from the most recent Thursday (we picked Thursday because this is when average prices are usually found).

30 day and 7 day prices fluctuate based on demand and availability at the time of search. For example, the 7-day price in summer is likely to be more expensive than the same journey in winter.

Prices are sourced in GBP and converted to other currencies using the daily market exchange rate.

We're always seeking to improve how price-checking works, and we welcome feedback on how we can make it better.
