And why should they care? I paid the full price of the ticket. What's it to them where I get off?
Sure they might think they can sell me food or drinks in flight or annoy me with their stupid branded credit card on every single flight, but the fact is I paid for the seat. If I don't show for my initial departure flight, they don't get worked up about that. Why is skiplagging any different?
Because they want to make more revenue by making it more expensive to fly to my intended destination? Well... don't do that. This is the natural, economic response to their pricing games. If you make it a game, people will play the game. Don't cry when you can't win 'em all, airlines.
