I'm glad you enjoy this game. You list the rules here very succinctly, and very understandable for someone reading who may not have played before.
There is one point I disagree with though, and maybe it's because I'm reading it wrong:
Every player must draw two purchased spoke counters from an opaque container. If a person owns either of them they collect the income amount printed on it with big payoffs for owning all spokes of a hub if the hub counter is drawn. This is where the game can become like Monopoly, more often than not a players counters keep coming up while others do not. Thus making the rich richer and the poor poorer.
In it's randomness, Air Baron really does give each player's chits the same chance of being picked. Where the rich players get richer, is where they have more chits in the cup to be drawn. If a player goes into fare wars early and is successful in winning several chits, they do have a higher percentage chance of getting paid. That's a part of the strategy of fare wars early, and sometimes I'll go after a whole bunch of $1 spokes to try to get paid the $3 if the Hub is pulled. You're not going to run your market share up, but you can definately increase your odds of getting paid that way.
