Trip Arbitrage is free to read. It is paid for by commissions: when you follow a booking link on this site and buy something, the company you bought from may pay us a share. You pay the same price either way.
Booking links appear in a section headed “Booking a trip” on country and city pages, and beside some tools. They are labeled as partner links and carry the technical marker (rel="sponsored") that tells search engines the same thing. Links inside articles to sources and official sites are never paid.
No display advertising, no pop-ups, no sponsored articles, and no selling of reader data. If that ever changes, this page will say so first.
Some links are to financial products such as multi-currency accounts and payment cards. What we write about them is general information, not personal financial advice. Terms and fees change; check them with the provider before you sign up.
How the index itself is built is on the method page. Who is behind the site is on the about page.
