You still don't know how much other people paid. Just because you did a search and found low prices does not mean that everyone else paid those lower prices - or did you go to each passenger and ask them what they paid? You are also still ignoring the fact that people don't buy seats, they buy a permit to travel in effect. Different prices have different conditions. It is still feasible that someone may have purchased fully flexible tickets even though there were cheaper buckets available. A client of mine did the same in purchasing my tickets to VIE the other week. CE return around the 1k mark. I know that there were tickets available quite a lot cheaper but against my advice the client insisted on paying full flex J.
You're so determined to find fault that you aren't seeing the wood for the trees.
