Then why not take the step to introduce "Automatic pricing" altogether, as an option to manually pricing routes.
I find the current manual pricing system lacking in terms of no way to "research" the outcome of pricing apart from gradually change prices again and again and see how it affects profit.
"Automatic pricing" is in fact a feature of Airline Empires and is actually pretty handy without taking the tactical thinking out of the game. I believe it works by a separate calculation server that processes routes on regular intervals. And it tries to set a price to achieve maximum profit (although not as optimized as manually researching best prices).
This would give the following the effect; If you're alone on a route, the system will (let's say once a week) calculate supply vs demand taking into account things such as RI, CI, type of aircraft, service levels, departure time, num of connections and other factors that make passengers decide wether to fly or not. It will then set a price that tries to achieve maximum profit (or minimum loss, if a new route or tough competition), which would mean that initially a new route will be priced very low and then getting more expensive as RI picks up.
If you later on get competition, your LF will drop and the effect will be that your price will be lowered to try and compensate and still achieve maximum profit (or minimum loss).
The effect it has on a game in Airline Empires is that competition is quite different in terms of pricing levels and what type of plane to fly different routes. I've had to get rid of bigger planes several times as I've been unable to turn a profit whilst competition with smaller and more suitable planes have been able to turn a small profit. Overall I'd say competition and profit making is much more sensitive. It's hard to explain exactly the effects of "Automatic pricing", but from my experience trying Airline Empires, there's definitely room for it. And even though Airline Empires is inferior to Airwaysim in many ways, I'd suggest giving it a quick try for no other reason than to see the effects of the way "Automatic pricing" and competition works.
