Spam lines are probably the most annoying thing about the game
You have airlines that provide more seats than the daily demand, sometimes it unintentional or not, some want a monopoly, some may have started that way and later had competition and larger planes and didn't want a market untouched. what makes it even worse is when they do this AND lower ticket prices to just extremely low levels
my thought on ending it (at least in some worlds)
1. Set a MINIMUM ticket price for each world, setting anything less than that ticket price will give a notice and set it to the minimum
2. If there are more seats than demand on the market, then any airline at the minimum price will have seats divided up between them evenly
example if minimum ticket price is $50 and 300 seats daily demand with 3 airlines each with 400+ seats/day, and say each airline has ticket prices at $50, then each airline can get no more than 100 seats/day as they can't lower prices any further
this discourages airlines from just overproviding to monopolize a market and makes them have to think more about route planning
obviously it should apply mostly to economy, I do think we should make business class and first class care more about IFS (so if IFS is equal then this applies, otherwise the airline with better F or C IFS gets more passengers).
what do you think? any other thoughts/ideas or changes to this idea?
