Prices explained

At Loco2 we believe in price transparency. We use real data from Loco2 searches to estimate the cheapest fares you should be able to find for your journey, based on how far in advance you book.

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.

30 day advance and 7 day advance prices are found by searching exactly 7 or 30 days from today. These prices fluctuate daily based on demand and availability at the time of search. For example, the 7-day price on a busy Saturday in summer is likely to be more expensive than the same journey on a Tuesday in winter.

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