Skyscanner works with over 1,200 partners and makes money from commissions and sponsored advertising. They also offer integrations for third-party travel companies. But while you will see sponsored ads (even from non-travel companies) on the Skyscanner website, rest assured that they will not affect your search rankings. Skyscanner is reliable because the site doesn't allow companies to pay for a higher rank in the search results and provides honest ratings alongside each company, whether they are particularly flattering.
