In all honesty all this thread is people complaining about something they don't have a clue about. Airline pricing is insanely complicated, and this is for a reason. Airlines are not a luxury business, they barely manage to survive. If not all this dynamic pricing, special contracts with agencies, etc, they'd have to charge so much for a seat that you wouldn't pay and all this travel industry you are accustomed to simply wouldn't exist. The whole business is built on making somebody who crucially needs to fly pay as much, as he can, and then to make price attractive enough for the rest of us so that you can sell the rest of the tickets, so that flight can make any profit. And in the end, margins are super thin in this business.
Also, your question implies that you imagine that there is some simple enough "true price for a seat", which is so far from the truth, you have no idea. If you actually look at the price breakdown for a given ticket, there are literally dozens of components in it. It's not unusual that so called "fare" of a ticket (which is, like, "just price") may be literally $1, and the rest of $300 is various taxes, surcharges and payoffs I won't even try to start to explain here.
I mean, really, people here truly have no idea what they are complaining about. Airline pricing is not a thing you should hate.
