To any new players that happen to chance upon this:
1. If you have hundreds of routes, it's just not worth the time to edit each route to squeeze out a few extra $.
2. More importantly: to stop the price wars. At some point, realize that it's better to take a 93.18% Load Factor earning you 50k than each of you going down, down, and further down until even though you have 100% load factor you might only be earning 30-40k. I remember in the Public Worlds the LHR - CDG route, what you would think would be one of the most profitable due to insanely high passenger counts in both places, and the low fuel, actually only ended up earning you 40k tops by year 5. Why? Everyone wants a piece of the pie, and they want their piece of the pie to by 100% of the theoretical size. Unfortunately, they were giving away bits of the pie in the process...
One of my routes in my current game: Frankfurt to Rome.
There are 4 of us there, and everyone priced it at 330. My LF is only 79%. However, I know if I break this balance that we have here, it'll only start to hurt as the price will drop, 1 euro at a time, to god knows what.
