I used kiwi.com to book my recent trip, I made it to my destination and back but I'll probably never use kiwi.com again. The only reason I booked my ticket on kiwi.com is for the lower price but that came at a huge cost i.e. inconvenience, stress during travel and also more actual cost in terms of dollars. I'd consider kiwi.com if and only if my itinerary does not include any stopovers OR if the entire trip is booked on a single airline OR if it is booked as single ticket even with multiple airlines. Details.... 1. Usually airline tickets are booked based on one main airline(a single ticket). i.e. that airline is responsible for arranging alternatives if a delay or cancellation occurs for some reason. kiwi.com on the other hand books tickets separately i.e airline handling one leg of your travel is not aware of your next leg. if for some reason your flight in the first leg gets delayed and you don't make it to the flight in next leg, the airline is not going to help you in anyway because as far the second airline is concerned your trip is originating in the middle they do not know and are not concerned that you trip started somewhere else and either airline will be responsible for missing your connection. kiwi.com can help if you signed up for some kind of protection which comes at extra cost 2. Being separate tickets and different airlines your baggage is not checked-in to your final destination. so you have to pickup your baggage and re-checkin with the next airline. this in itself does not sound too bad but consider leaving secure side of the airport going to baggage carousel, pick up your bags go to the airline counter and recheck-in your baggage and get new boarding passes and again pass through security. 3. Being separate airlines the connections are not always in the same terminal or terminals that are internally connected. You might have to collect your baggage and leave the airport, arrange travel to the terminal of the other airline.... 4. The previous point made it very difficult for me during COVID times. My PCR test which was done within the acceptable time(72 hrs for my country of destination at the time of my journey) at the start of my journey became unacceptable because the next airline treats as if your journey is beginning there. So I ended up having to leave airport find a place where I could get another COVID test and pay the airline for rescheduling the ticket for my next leg. All in all kiwi.com is not fraud they do book the tickets and they are cheap at first, but by the time you add all the protections which come at a cost, the tickets are not cheap anymore and at that point I'd rather deal with airline for any issues than with kiwi.com's customer service. Don't book on kiwi.com for the price when you add the necessary protections the price goes up and goes up significantly.
