I paid $254 dollars for reservations with two airlines that would get me from Washington D. C. to Mexico City through kiwi. I got the "standard" package so I could rebook if I needed to. I missed the 48-hour window by a few hours and they refused to let me rebook. I got the reservation numbers and looked up the flights on the airline websites. The total for both reservations was $190. Lesson learned it's not worth trying to save $10 using Kiwi.
