Flooding routes to that degree is not realistic, but the root cause is that large AE airlines are wealthy enough to do that and bleed cash on a route indefinitely, and many are willing to do so to get competitors off certain routes. This fundamental problem is something we're aiming to fix in AE 4
Yes! An end coming to airlines that flood the major airports with 112x weekly flights. (I think I saw that for an airline somewhere in AE, but can't remember where.)
