Skyscanner is showing flights from very shady unknown companies that offer up flights that don't exist or maybe were canceled some time ago. These shady companies will gladly take your money and fight to not give you a refund. For example an Air China flight from IAH to TSN is showing for $5077 on May 19th on Skyscanner using Hop2, Justfly and several other unknown outfits. Air China currently offers NO flights on this route. Maybe they some months ago before Covid-19 but these places will still take your money offering tickets on a non-existing flight. The reviews on these companies are terrible. Maybe some of these companies are the same with just different names. Very disappointed.
