Kiwi.com Promo Code 2026: €20 Off Flights

Virtual Interlining is the proprietary technology that fundamentally sets Kiwi.com apart from all other flight comparators. The idea: combine flights from different airlines that have no codeshare agreement, to create a complete itinerary cheaper than the available direct flights.

A concrete example: instead of paying €600 for a Paris-Bangkok flight with a single airline, Kiwi.com can offer Paris-Dubai (one carrier) + Dubai-Bangkok (another) at €320 — two separate flights, intelligently combined by the algorithm.

The Kiwi.com Guarantee: if you miss your connection because of a delay on the first flight, Kiwi.com rebooks you on the next available flight or refunds you. This is what justifies trusting an apparently risky model. For short trips by long-distance bus, Flixbus is often faster on European routes.

Kiwi.com offers several saving mechanisms:

Promo code -€20: available on bookings of €200 minimum, enterable at the payment step. It's the most accessible discount for new users.

Code -€40: distributed occasionally during seasonal campaigns. Check the offers on this page before any major booking.

Kiwi.com newsletter: subscribers exclusively receive flash offers on specific routes. These offers can represent savings far greater than standard promo codes.

Kiwi.com Guarantee: included in each booking (for an optional supplement), it covers rebooking or refund in case of a delay on the first flight of a Virtual Interlining itinerary.

Virtual Interlining isn't a promo code but generates savings often far greater than all available codes. It's Kiwi.com's real value proposition.

The Kiwi.com Guarantee is the product that makes Virtual Interlining viable for travellers. Without it, taking two flights from different airlines with no codeshare exposes you to a real risk: if the first flight is delayed, you miss the second and the second airline has no obligation to refund you.

With the Kiwi.com Guarantee (added at purchase for a few euros):

• If you miss your connection due to a delay or cancellation, Kiwi.com rebooks you on the next available flight
• If no alternative is available within a reasonable time, Kiwi.com refunds you in full
• Kiwi.com handles communication with the airlines on your behalf

This guarantee turns the theoretical risk of Virtual Interlining into a protected service — comparable to a single-airline connecting flight.

On Kiwi.com, two types of saving are possible and work differently:

The promo code (-€20 or -€40) is a direct discount on the final price of your ticket. It applies to eligible bookings, excluding taxes and fees. It's entered manually and is single-use.

Virtual Interlining is a structural saving: by combining flights from several airlines, Kiwi.com finds itineraries cheaper than conventional direct flights. It's not a "code" — it's how Kiwi.com builds your itinerary. On a Paris-Bangkok flight, the gap can exceed €200 vs traditional comparators.

The ideal combination: use Virtual Interlining to find the cheapest itinerary + apply a promo code on the final booking. To compare with train or bus alternatives on European routes, Omio shows all options simultaneously.

Kiwi.com generates the biggest savings via Virtual Interlining on long-haul destinations poorly served by direct flights:

Southeast Asia: Bangkok, Ho Chi Minh, Bali, Kuala Lumpur — combinations possible via Dubai (Gulf carriers), Istanbul (Turkish Airlines) or low-cost European hubs

Latin America: Buenos Aires, Lima, Bogotá, São Paulo — itineraries via Madrid or Lisbon often cheaper by combining low-cost + local airlines

Sub-Saharan Africa: Nairobi, Lagos, Accra — Kiwi.com can identify itineraries via Casablanca (Royal Air Maroc) or Dubai much cheaper than direct flights

Oceania: Sydney, Auckland — combinations via Singapore or Tokyo with Asian low-cost carriers

On short European destinations (Paris-Rome, Paris-Berlin), Kiwi.com is less differentiating — Google Flights and Skyscanner suffice.

Google Flights is unbeatable for monitoring prices and finding the best dates. Kiwi.com is essential when Virtual Interlining can create a cheaper itinerary. Skyscanner is useful for multi-airline comparisons in a few clicks.

Kiwi.com was founded in Brno (Czech Republic) in 2012 by Oliver Dlouhý. The company quickly established the Virtual Interlining concept and became one of the most innovative flight booking platforms on the market, with billions of dollars in tickets sold annually.

Strengths: Virtual Interlining unique on the market, connection guarantee for combined itineraries, promo codes available, very good for atypical long-haul destinations, a clear interface.

Watch-outs: some Virtual Interlining savings involve connections at non-optimal airports or longer travel times. The guarantee doesn't cover every scenario — read the conditions. Customer service can be hard to reach in an emergency.

The Kiwi.com promo code is valid once per account and applies to eligible bookings of €200 minimum. It can't be combined with other active promo codes.

The code must be entered before payment confirmation — no retroactive application is possible. Check the expiry date shown on this page before using it.

Kiwi.com tickets are named — check that the name on your ticket exactly matches your passport. If you have a problem entering the code, Kiwi.com customer service is reachable via the chatbot on the site.

Kiwi.com was founded in 2012 in Brno, Czech Republic, under the name "Skypicker". The name changed to Kiwi.com in 2016, with the ambition of making it an international brand. The company developed Virtual Interlining technology in-house — an algorithm able to combine flights from airlines without codeshare and to guarantee connections.

In 2017, Kiwi.com raised €60 million in a Series A from General Atlantic — recognition of the value of its proprietary technology. The same year, it launched the Kiwi.com Guarantee, turning Virtual Interlining from a risky option into a reliable commercial product.

Kiwi.com has since developed its offer with hotel bookings, car rentals and airport transfers, approaching a full OTA. Its strength remains combined flight tickets, for which no competitor has yet developed equivalent technology. We update this page regularly to guarantee the best Kiwi.com promo codes.
