When you try to book the tickets, they are putting pressure on you to purchase your checked-in baggage for the inflated price. They state, you have to do it right now and this way save 20% compared to what you gonna pay at the airport counter. And it's a big LIE, because in reality you gonna pay Kiwi x2 more than if you would do it during your check-in process. So they wanted me to pay $121+ for up to 15 kg suitcase, but their greed eventually ruined the deal, as I found this fee suspiciously high. Long story short - I was charged $40 (33% of their demanded price!) for the max 23 kg suitcase simply by purchasing the same flight directly from the company. Bye-bye, scammers! Nice try, though.
