VERDICT

Should I use Momondo?

Cheap Flights - Search and Compare Flights - momondo.com

Worth it. Free metasearch that consistently finds cheap fares — use it to compare, then book direct with the airline when the price is close. Skip it if you need one accountable party for refunds, disputes, or corporate travel policy.

Confidence

Gotchas - check before you buy

Support depends on the third-party seller you book, not Momondo

Fake 'Momondo customer service' phone numbers circulate; use only the official help page

Some airline fares may be missing due to scraping disputes like Ryanair's
