On a two-way trip from New York to Berlin via Amsterdam, Kiwi.com managed to get me stranded twice on Amsterdam airport: On the first flight they "forgot" to pay KLM for the flight ticket Kiwi.com should have purchased for me resulting in me having to buy another ticket for that flight 1 hour before departure (you will know how costly that was) and I'm still waiting for my refund. On the way back, the first flight was delayed (Kiwi.com probably hasn't any fault in this) resulting in me missing the follow-on flight. However, they were not willing/ able/ capable??? to book my on the only other flight to New York that day (despite the fact that I had informed Kiwi.com 4 hours prior to departure of that other flight about my delay). Now being stranded in Amsterdam without my luggage, Kiwi.com instead offered me a refund of my flight to New York (which was ca. 20% of the price of a new flight at that time) or a new flight the next day with a 1-night stay in Amsterdam ("All paid for by Kiwi.com). Having arrived at the "airport" hotel, I realized it was 15 minutes taxi drive from the airport (of course I had to pay for the taxi) as well as a 40 minutes drive to Amsterdam city center with no other restaurants or activities close by. Then, Kiwi.com had promised to pay for breakfast, dinner and the hotel room - none of this was the case! I had to pay for all myself (reimbursement is filed but as they have so far not reimbursed me for my first flight 4 weeks ago, I am certain I will either not get any reimbursement or it will take weeks). Last but not least: The original ticket price was just 5% cheaper than if I would have booked it directly with the airlines. I am 100% certain, I will never use Kiwi.com again and cannot recommend it to anyone - not even to save costs as in the end, you will pay more!!! And you will waste a lot of your precious lifetime waiting on airports and speaking to (10!!!) customer service agents that are all very friendly, but seem to have no flexibility or rights to make decisions. Also you have to call them as they "cannot" (or don't want to?) call you back. Of course it's not a toll-free number so you will also have additional costs here. All in all: Using Kiwi.com saved me 5% vs. the alternatives on the ticket price, but so far I have paid at least 15% more due to the additional costs that Kiwi.com promised they would be paying, but didn't. For me this company sounds like scam and everyone who ever thinks of using it, think twice!
