VERDICT

Should I use Kayak?

Search Flights, Hotels & Rental Cars - kayak.com

Worth it. Use KAYAK free to compare flights, hotels, and cars — the search side is solid and the app is well reviewed. Most complaints come from third-party bookings, so book direct or with a seller you trust.

Confidence

Medium. Based on ~15 usable public sources; many review snippets were truncated, and several 'kayak' results referred to boats, not the travel site, and were excluded.
