Kiwi.com review: cheaper flights by combining 500+ airlines

What is Kiwi.com?

Kiwi.com is an online travel agent focused on flights. The website and app are operated by Kiwi.com s.r.o., registered in Prague, Czech Republic. According to the company, it processes over 100 million searches a day across more than 500 airlines.

Kiwi.com does not fly anyone itself. It books tickets with the airlines on your behalf, and the contract of carriage is between you and each airline. Its signature feature is virtual interlining: it connects flights of airlines that don't cooperate into one itinerary, which can be cheaper than a standard ticket. The trade-off, which its terms spell out:

• on a self-transfer layover you collect and recheck your luggage yourself;
• you will probably pass through customs, so you may need a visa or entry documents for the layover country;
• an airline is not obliged to rebook you if a delay on one flight makes you miss the next.

Kiwi.com may also offer “Smart Tickets” (hidden-city or throwaway fares), clearly labelled; some airlines prohibit this practice in their own rules.

Prices and fees

The Booking Price shown at checkout is broken down into the carrier's price (fare plus airline extras such as bags), any third-party extras and the Kiwi.com Service Fee. Unless stated otherwise, the service fee is not refundable.

Flight prices change quickly. If the airline's price rises between your payment and the moment Kiwi.com buys the ticket, it may ask you to pay the difference or cancel and refund you. For some itineraries it offers a paid price lock that holds the fare for a set period.

Promo codes and vouchers issued by Kiwi.com can be applied during booking under their own conditions. Kiwi.com Credit, used for refunds and compensation, is non-transferable and valid for 24 months.

Cancellation options

If you cancel for your own reasons (the flight itself is not disrupted), what you get back depends on the fare type you chose:

Cancellation or rebooking must be ordered at least 48 hours before the first flight (4 hours if Flexi was bought less than 6 days before departure). Cancelling an unconfirmed booking immediately returns 90% as Kiwi.com Credit. Many cheap fares are non-refundable, so a Saver refund can be zero.

Kiwi.com Guarantee and disruptions

The optional Kiwi.com Guarantee bundles:

• Disruption Protection – if an airline cancels, reschedules or significantly delays a flight, you can take instant Kiwi.com Credit to book an alternative right away, or have Kiwi.com claim a refund from the airline. If an overnight stay becomes necessary, accommodation booked through Kiwi.com's link is reimbursed up to €150.
• Automatic check-in – add passport details at least 24 hours before departure and boarding passes arrive by email and in the app.
• 24/7 support through AI chat in any language; human agents reply within 3 hours, prioritising imminent departures.

You lose these rights if you change the reservation directly with the airline, or if a disruption comes from missing passport or visa documents.

Who Kiwi.com is for

• Budget travellers who want the cheapest route and are comfortable with a self-transfer layover.
• Flexible planners who compare dates and airports to find low fares, including with low-cost carriers.
• Worry-averse bookers who add the optional Kiwi.com Guarantee for instant credit on airline disruptions and automatic check-in.
• Multi-airline trips that no single airline sells in one ticket.

There is no promo code to type through our link and no extra discount; prices and fare options are the same as when you visit directly. If you need one airline ticket with a protected connection, compare it with a standard fare first.
