Ticket price vs. distance

[Pe11e]

Ok,

I know that the price settings match the 1000km flight distance, no?

So, If I set a low price settings of 350$ at the start of a company, it will be like this:

500km flight = 175$ ticket price
1000km = 350$
2000km = 700$
4000km = 1400$

and so on...

In real life, a price of 1400$ for 4000km flight is ultra expensive and completely unacceptable! And this is low ticket price settings in FSP.
Imagine a ticket price for long haul flight (8000km = 2800$, lol).
Some airlines in Europe have a ticket price of 100$ for a 1000km charter flight (I bought a ticket myself), and this price in FSP is a lower than bargain.
The ticket price of 350$ at the start is completely ok, for good progress of company, but anything below that is, especially under 250 is bad.

Can someone explain the ticket price system in FSP?
Sorry if I asked the question that is already been discussed.

Thanks in advance!
