I was a bit afraid because of reviews, but everything was great, I bought four tickets (transfer flights) and got every ticket 24 hours before flight. Tried to use helpdesk platform - I got message like in 2mins. I guess you pay the price (which is low) but you need to be prepared for two things: 1. If you have transfer flights, be aware of time, do not book second flight less than 3 hours after your first flight. You can miss it. 2. Just know: if you paying cheap tickets, do not expect refund. I was checking updates and info in kiwi app constantly therefore did not experienced any problems. Moreover had no issues with raynair - got the tickets with QR code 😄 also, forgot to mention, fill check in details as soon as app will let you to do it!
