My issue with google flights is heavy cache on smaller routes. My country needs 2 layovers to get to NZ which massively increases search space. Pretty much every result is “oops we can’t find this price anymore, it’s now 10x”. It’s still ok for finding some routes or ideas, but far from best for cheapest (ie it cant find cheapest country to book from like skyscanner). And don’t even get me started on business flight search - that’s basically conspiracy from airlines for you never to find deals.
