Counterquestion: Is it forbidden to have multiple bases/hubs at the moment?
Answering my own question: No, it isn't. Thing is, there's no mention of a certain base/hub anywhere in the game. (Let me know, if I'm wrong about that.
) You're free to send a few of your planes to any airport and start services from there. Even if you're counting your airline's headquarters as a hub, it's nothing more than some standard gates without any bonuses. And as far as I can tell, some people are already operating with more than one base/hub; otherwise my airline's current life would be a bit easier.
