I bought a flight ticket through an agency; the flight was delayed 24 hours and I suffered losses. The agency says "take it up with the airline", but the airline doesn't even have a liaison office in Türkiye. What should I do?

As a rule, agencies have no control over airlines and are not liable for decisions outside their control. However, there have been cases where — precisely because the airline had no liaison office in Türkiye — liability was imposed on the agency instead.
