First off, I just joined the community this past weekend and I'd like to say hello. Currently have a couple airlines in R1. I chose this world because I liked the idea of starting an airline at the beginning of a long-duration time period. Any general advice for long-term success (or at least survival) would be helpful.
In particular, I'm wondering whether establishing a hub is practically useful? From reading the forums/guides/etc, I think I understand the basics. That is, the hub allows you to fill otherwise empty seats via connecting passengers from Alliance members. For this, you pay twice the gate fees and only get half the ticket price.
1) At first glance, this doesn't sound like much of a benefit. Is there a deeper benefit buried in the game mechanics that I don't know about?
2) Are hubs useful in a practical sense? Do you go out of your way to build them in a typical game? Or, more directly, will you do just fine never bothering to build one at all?
3) Does the presence of a hub artificially increase passenger demand from a particular airport? What I mean is, if a hub is a location where passengers are essentially "dumped" to await boarding on another flight, does the presence of these out-of-town passengers cause demand out of that airport to increase above its base value?
4) How dynamic are the PAX? If demand is X for a ATL-DAL flight but no such route exists, Will PAX instead fly a ATL-PIT-DAL route. In other words, do PAX attempt to find a route to meet their demand, or does the ATL-DAL demand simply go unfulfilled until someone establishes a P2P route?
Thanks, in advance, for your help!
