MSQ had brought up that airships weren't viable because they'd be weighed down by the amount of fuel required to make such a trip, assuming they weren't shot down by the Garleans to start.
If you actually leave the ship before doing the Sirensong Sea dungeon, the NPC will act all surprised at how you're back in Limsa and complain that they need to send you back on their next fastest ship.
But given what we know of airships currently, most of the ones of Eorzean design do not appear to hold much cargo. Nor are they particularly large either. (But this could just be a game model issue).
From my understanding, ships are still the most viable means. I suppose someone could use aetherial teleportation if they've visited before, but that would likely involve a very large amount of anima in addition to the regular teleportation caveats like a limited amount of items to bring along, aethersickness, and the like. This too, is mentioned in the game when Alisae talks about having restored an aetheryte crystal in the Doman hideout.
