Following up on Adam's discussion below about Flyht Myrcia, I've created an code-sharing airline alliance, Geolliance. The wiki page is pretty thin, but there's space to add airlines and hubs there (no table yet, but that can be added once airlines join). And I'd love to have at least one or two other airlines to join Air Wiwaxia as founders as well. The alliance particularly needs airlines that fly more outside Eastern Uletha, i.e. Archanta, Tarephia and Antarephia, as well as Western Uletha.
As discussed earlier, there might be other alliances created with Air Ataraxie as a founder of one and KojAir as founder of another, so if you already have code-sharing deals with either of them you probably don't want to be part of this alliance.
