> often waste a huge amount of time find the best flight Would you trust that this would book you the "best" flight? Every user has a different definition of "best" – cheapest, shortest, fewest stopovers, shortest stopovers, airline preference, lounge preference, seat preference, time of day preference... Personally I find Google Flights gives me the right amount of detail and I book flights I'm happy with.
Yeah, I'm kind of surprised by all the uniform praise in the comments - NOT saying it's not a cool tool, it's definitely very impressive and the author's done a nice job, but I could never really see myself using this. Mainly just because flights are super expensive, I can't see myself trusting a bot to make the best choice instead of spending 10 minutes of my own time to potentially save a lot of money. I guess it's…
Bots can analyze several thousand flight options (which even the sim does) in a few seconds. So odds are it catches a deal someone might otherwise miss.
Also, because BonBook searches direct w/ airlines, it sees inventory not shared with Google (and regularly has better fares).
