I had the same question (about how soon demand in general will start to grow, and how quickly)... I'm one of four airlines based in Detroit (which was a pretty happening city in 1955!), and the four of us have basically already saturated all of the routes of any significance. Some routes have been flooded with 4x the level of seat demand.
I admit that I'm part of the problem (I've got 18 planes in my fleet with 4 more on order), but it just feels like the seat demand is too low for the number of people in the game. At this point, I feel like I've pretty much done everything I can do... there's no more seat demand (or very little), so I'm presuming we just sit back and do nothing until demand grows...? With current demand, I certainly can't get any more planes
And yes, I know I can shift times around to match my competitors' routes, undercut their rates, and try to force them off certain routes (or put them out of business). But it's the start of the game, the four of us are all of a similar size, and frankly I'm not in the mood to start a ticket & route war that will likely end up being just as destructive to me as it is to the airline I target.
Can any more experienced players tell me what I'm missing?
