I will never book with kiwi again and I will recommend all my friends to NOT to use it. In my experience the service is very bad. Here what happened to me: We booked a flight from Bahia Solano to Armenia (with layover in Medellin) with Kiwi. The airline operating the flight was called Easyfly. In the booking process I chose to pay extra (34,20 euros) to be protected by "kiwi guarantee". This is a service that promises the following: "Our Kiwi.com Guarantee is a unique extra service that covers you if your trip gets disrupted because carriers changed, canceled, or delayed any part of it. If that happens, we’ll get you to your destination or can immediately send you a refund." In our experience this is absolutely not true!!! When we got to the airport 2 hours in advance our flight was disrupted (even though we had a reservation) and we could not fly. We spend the entire day at the airport trying to find a solution but we never got to our destination. Easyfly (the airline) didn't find us any alternative, didn't pay for refreshments or didn't pay for an extra hotel night. In this situation Kiwi Guarantee was completely useless, we called the helpline: they said they didn't refund the extra costs (hotel and food). They just found us an alternative itinerary which would make us arrive to the destination with a delay of 76 hours and for which we would have to pay extra 350 euros!!! Kiwi also didn't refund our flight immediately. Instead, they will ask a refund from the airline and if the airline refunds (which is very unlikely) they will refund us. This, according to kiwi, will take minimum 3 months!!! So basically, all the protection that the "kiwi guarantee" claims to offer is a very big lie!
