Keep in mind, the "default demand" is only a measure of the green pax. it doesn't include the bluey/purpley ones, which can be significantly higher, (theoretically limitless), depending on the level of hubbed, connecting airports you have (either yourself or in an alliance). And the more connecting pax you have, the more capacity you can, justifiably, put on the route, & the more you can charge them. I don't regard that as spamming - I just call that demand & supply, but I know others disagree.
That's not "supply and demand." You're trying to justify abusing a completely broken 'game' mechanic to a player that doesn't really understand how shady that is.
If I suddenly added a ton of flights IRL that cost 2-3x+ the going rate of every other competitor, regardless of service, I wouldn't suddenly be minting new passengers out of thin air, much less ones willing to pay absurd rates to connect a bunch of times inside my network. Connecting passengers are more price sensitive, not less. AE is completely broken in that regard. If you want to monetize your "theoretically limitless" passengers inside the fundamentally flawed world of AE, by all means, but don't try to justify it as being a wholesome reflection of market behavior. It's not. You are inventing your own supply that other players cannot compete with in any meaningful way. There's nothing at play in that scenario beyond your ability to acquire more airframes to put on your spamline. This behavior is a byproduct of the broken hub mechanics that I hope get fixed in the future.
This particularly bothers me because on R7 you started a perfectly normal airline that only leased Boeing airplanes, then at some point decided to stop that and turn into a full blown $pamliner, the first one in that world. I was suddenly seeing routes with 3x the going price on them from you. I had, at that point, not even attempted to monetize my connecting passengers and was otherwise playing normally. I had grown into the #1 ranked airline through careful expansion, capital outlay, and constant preening of my routes. I didn't even run scam IFS (still don't) and I paid my employees enough to keep them happy. Now, if I want to keep my top spot, you've completely painted me into a corner by going full spamline. Now the game is effectively between you and me, with other airlines completely oblivious. I'm more than okay with that, but to see you in this thread trying to come off as slick for 'playing' AE in such a manner is disappointing. It's also more than a little weird that you offer to help new players and presumably care about the well-being of the community yet you partake in some of the most cancerous gameplay behavior.
Ryan has nothing to worry about. He's got this. I hope he never falls to the darkside like you and I.
