I booked four flights , 2 on one day and 2 a month later, with Kiwi because they guaranteed the connection. Then the first flights on each day were cancelled by the airline. Kiwi moved my flights to the day before and then refused to help as, technically, I could still make my connections. I"m not sure how many people can just suddenly travel the day before, but I can't. The originally didn't even offer advice about a refund, they just told me to contact the airline. I did do that , but then I requested refunds on the Kiwi site and got them. The second airline didn't offer refunds, so I lost the money for my second flight and Kiwi support didn't even answer my second email. So I may use Kiwi in future to plan flights, but then I will book them direct myself. I most certainly don't trust them at all. The guarantee states If you're covered by the Kiwi.com Guarantee and there's a schedule change, cancellation, or delay that affects your trip, we'll either buy you an alternative flight to your final destination, or offer you an amount to be refunded. When you receive a notification that your trip has been affected, please always contact us back within 24 hours, or your Guarantee may be voided. When the Kiwi.com Guarantee applies: Your flight was rescheduled, delayed, or cancelled by the airline for any reason'. I'm confused but there is obviously no point chasing this any further. What can I do if they don't even answer emails?
