I never undestand this.

I think that is a good idea to be allowed to buy airlines. The shares could be put in a stock exchange by the owner like an IPO. The stakeholder could benefit from profit percentage.

I haven't found this to be a big problem since I usually stay off of trunk routes that everyone else competes on. There are many many medium-sized airports with unserved routes that large airlines don't bother competing on. Just yesterday I found at least 10 routes with 300-500 daily demand completely unserved (just typing in random US airport codes, not even using the "Browse Airports" function).

If a small airline jumps into the crowded trunk routes that jumps to everyone else's mind, of course he will find heavy competition.

I operate on 1250 different city pairs, and every day only 10 or so of them go negative due to competition. By choosing where you fly, you can control the level of competition you're exposed to.

I totally agree. There are even routes linking two major airports unserved like TPE, KUL, SIN and more.
