How we make our guides
Every guide answers the same questions: which options exist, how long each one takes, what it costs and what to watch out for. This page explains where that information comes from and how far you can rely on it.
Where the information comes from
- Distances and driving times are calculated on open road data (OpenStreetMap, with the OSRM routing engine).
- Transport options, prices and frequencies are compiled from publicly available information about airports and transport operators.
- Places and sights come from Wikipedia and Wikidata; photos come from Wikimedia Commons and other free sources, credited on the page Photo credits.
- Flight prices come from Aviasales / Travelpayouts data and are refreshed regularly.
- Exchange rates are updated every day.
How we check
We compare sample guides with the information the operators themselves publish and correct what we find.
Prices are approximate
Fares, timetables and routes change, sometimes without notice. Prices are converted at the daily exchange rate, rounded, and meant as a guide to help you compare options — not as a quote.
Before you travel, confirm the current fare and timetable with the operator.
Updates
Each guide shows the date it was last updated, under its title.
Corrections
If something is wrong or out of date, tell us through the page Contact. We review every report and fix confirmed errors.
Independence
