I have read the Strategy Guide and researched the threads but I am still unsure of when to create a hub.
According to the Strategy Guide, I should wait until I have about 20 gates, but I notice that many players create a hub with far fewer gates. I assume that results in a positive cash flow but not as significant as a larger number of gates.
Are there other factors that contribute to a hub? Such as % of airport traffic. number of cities served, frequency of flights? Or is it simply a matter of slots used?
well, a hub causes you gates to cost 2x more. So, I would wait until you have: A) A terminal with 25 gates (don't build a terminal with less!), Significant jet operations using jets 737 or larger, and C) A well developed route structure.
What do you mean by a well developed route structure?
Charge for unused slots at an airport. If you use one or 5 slots, it still represents one gate. And a lot of gates are being used for only one slot, thereby consuming the availible number of gates at popular airports.
There are numerous ways to institute this depending on what the objective is. For example, if you want to affect feeder airlines, then there will be an economic cost to owning a gate an not flying it.
One scenario, allow one idle slot but charge for any more idle slots.
Charge on a sliding scale, no charge for airports with more than 10 availble gates, a small charge for airports with 0-10 and a large charge for airports with 0 (maybe sliding with the gate fee).
The objective is to pay for idle resources in a scarcity environment.
Now that this round has been going for a while, what to do about the dead airlines, those who haven't been playing for a few weeks and are just ocuppying space.
(self interest note: I am interested in the gates they are sitting on).
It is free, but starting now has you at a serious disadvantage. Alot of airlines are well established and there are no more gates available, well you get 5 when you start but that's it ;-)
You wont make any money.
That's not strictly true, if you choose other than NA or EUR gates are availble but the ranges are so long, it is hard to make any money with small planes.
But I would suggest playing the game so that you understand some of the strategy behind the game play. You may not break the top 100 but you will be in a much better position to be a palyer in the next round.
