It’s quite remarkable to read genuine reviews here, by contrast with Trustpilot which I believe is itself simply a marketing scam. There one notices 5-star ratings are invariably at the top of the reviews, and many of them sound like ChatGPT fakes. I booked a flight from Italy to Great Britain through kiwi.com. The flight was cancelled due to technical difficulties so I missed the connecting flight from Paris. I was offered a replacement flight by the airline but this meant no onward travel until the following day. I called Kiwi customer service and they kept me on hold for 30 minutes and eventually told me to take the replacement flight and call them back at 22:30. This wasn’t acceptable because I would have ended up in the identical situation 3 hours later with no idea about hotels or time of replacement flight from Paris to Great Britain the following day. In any case Kiwi told me because I hadn’t bought a flight with guarantee I’d have to buy another ticket for the second part of the journey. From reading other reviews it’s apparent even with a guarantee the same problem arises. As well as keeping me on hold for a long time the customer service agent was and argumentative. He simply didn’t listen properly and kept repeating the information I’d given in order to find a loophole to refuse to help. No doubt what this company does is legal but all you get is a very slightly cheaper flight (however this is increased by hidden additional charges) with the probability that if something goes wrong you’ll get no help from kiwi.com.
