1. How Does Kiwi Work?

What is How does work? is an online travel agency that offers affordable and customizable travel options. Kiwi’s booking tool finds the best flight deals available for you. Kiwi searches through all airlines, both budget and traditional airlines, and then combine them to create the most cost-effective route. This distinguishes Kiwi from others, as they offer a one-of-a-kind virtual interlining system, allowing them to combine different airlines and identify cheaper travel routes.

Although you can plan a journey with multiple stops yourself, it will be more time-consuming. Kiwi flight booking tool makes the process easier.

Unlike most airlines, Kiwi does not prioritize codeshare routes while creating flight options. Kiwi will search for the cheapest options for you, even if it means booking you on two separate flights. Keep in mind that in this case, during your layover, you may need to check in again and re-check your luggage. Kiwi may also offer a flight in which a change of airport is necessary, or offer you a flight out a secondary airport.

Keep in mind that cheap travel deals may not be the most convenient option, but it’s great for budget-conscious travelers with more time than money.

2. Protected Self-Transfer Flights

This is the main reason why we love so much.

And this is how Kiwi is known to general public – as a service which offers to book protected self-transfer flights. Because as you might already know, not always self-transfer flights are safe.

While by default, self-transfer flights booked with Kiwi aren’t protected by the either the airline or Kiwi itself, there’s a possibility to book a special flight insurance for flight protection. This special insurance is called Kiwi Guarantee. It provides protection against changes or cancellations caused by the carrier. This service is available for all types of transportation, including flights, buses, and trains. 

Kiwi Guarantee, Kiwi’s self-transfer flight insurance, used to be a free service, but now it’s not free anymore. Its cost varies depending on the price and route of your booking. Guarantee assures you that you will not miss your connecting flights if you purchase it. Kiwi Guarantee provides coverage in the following situations:

  • If your trip or part of it is canceled.
  • If your trip or part of it is rescheduled with a delay of more than 24 hours.
  • If your trip is rescheduled or delayed, causing you to miss your connecting flights.
  • If your baggage is delayed or if there are lengthy queues at the airport, resulting in a missed connecting flight.

2.1 Notify Kiwi Immediately

It is important that you notify Kiwi immediately when you become aware of a flight delay, cancellation or schedule change. Depending on how close it is to your departure, Kiwi will provide either an alternative itinerary or a refund for your disrupted travel plans. Please make sure to promptly respond to any alternative itinerary offers made by Kiwi.

Keep in mind that Kiwi’s insurance policy does not provide coverage for force majeure events or other extraordinary situations.

2.2 Don’t Make Any Flight Changes!

Don’t make any flight changes without‘s approval!

If you make changes to your trip or contact details with the airline without informing Kiwi and getting their approval, Kiwi Guarantee will not apply to you. This includes situations like adding checked baggage to a non-checked baggage trip or changing to an itinerary with a short layover that doesn’t allow enough time for transfer.

2.3 Kiwi Will Help You If You Miss a Flight

If you miss connecting flight due to delay, Kiwi will assist you and book you on a new flight – because it wasn’t your fault the flight was delayed, and you missed your connection.

  10. After you’ve completed your booking, you’ll receive a confirmation email with your itinerary and booking details.

There are a few things you should keep in mind when booking a self-transfer flight with Kiwi.

If you have a long connection time, you may manage a short trip to the city. Keep in mind that you may need a visa for your self-transfer flights. Even if you do not plan to leave the airport. 

If you see that there are options including a country where you are required a visa, you can use a filter to exclude this country (“Exclude countries”).

As these are self transfers, Kiwi may offer you an itinerary in which airport change is required. If you don’t want to travel between different airports, in the filter section on the left, deselect “Self-transfer to different station/airport”.

If you don’t want overnight stopovers, deselect “Allow overnight stopovers” in the filters. 

Don’t forget that you may have no checked baggage allowance on self-transfer flights, especially if you are flying with low-cost airlines. It’s important to check baggage allowances as they vary among airlines. Packing light or using a carry-on bag may help you avoid additional fees.

When using, you can select stopover duration, and add multiple departure and arrival airports. Additionally, you can utilize the “Radius” feature (pictured below) to broaden your search and discover cheaper flights in your vicinity. This is especially useful when you can access a nearby city through affordable public transportation and that city offers more reasonably priced flights.

Use the price alert feature if you want to get notified when the price of a flight drops. You can receive these notifications via your e-mail or push notifications on your mobile device.

It’s important to check baggage allowances as they vary among airlines. Packing light or using a carry-on bag may help you avoid additional fees.

If your itinerary involves stops in different countries, make sure to check whether you will need a visa for your multi-city flight.
