They charge you for free services. Kiwi.com said I had to pay for any checked baggage, so I paid for 1 checked baggage and was planning to take my second one(smaller) on the plain with me. When I was doing the check-in, the person at the airline desk told me that my ticket fare included 2 checked baggages for free, that all their economy fare was like that, no extra charge for any checked baggage. So I checked my smallest one too, free of charge of course. After that I've contacted kiwi.com but they don't reply my inquiry, I've paid about 255€ to kiwi.com for one checked baggage, when there was no need to, this is how they make money, robbing you like that.
