First, THANK YOU to the admins for giving us somewhere to talk about this. Every time I've tried to give comments on this, the thread has been shut down already.
In terms of the topic itself, why are people complaining about this. The number of routes with $1 fares are tiny compared to the number of routes around. Some people make these routes just to join their hubs. I've heard that the small airlines are whining about this but I have a question for them....
Why are you insisting on opening a route on an extremely competitive route frequented by planes worth more than your company? This to me seems akin to every software company on the planet deciding that they need to make an OS or MS Office clone and compete with Microsoft. If you're a small airline, find some niche routes out of less frequented hubs. You're not going to be successful if you use gates in London Heathrow and expect to make money on routes between it and Munich, Paris, Rome, Berlin, Stockholm, etc. It's a stupid strategy. I look at these $1 routes and see plenty of small companies wasting planes flying them and then complaining about it. They should be complaining about their own lack of skill in the game.
For the players with plenty of money, I doubt highly that the $1 routes matter much as there aren't that many of them. There is obviously a downward trend on fares throughout the game as the number of planes and airlines increase. It's the nature of the beast and quite frankly anyone who has flown on a commercial airline has benefited from this. That said, the more experienced/smarter (have to throw that in cause I'm new at the game, but have a multi-billion company) players won't drop every fare to $1 or by $1. They will lower it to match the lowest fare and when we bring in lower fares, it is because we have larger planes and need to fill them.
Should we have minimum priced routes? No. Is it ok that there are $1 routes? Sure. Should people complain about it? Hell no. IF you own a business and can't compete in a certain market, then you don't sell in that market.
