I don't know about you guys, but for me and my friends one of the major milestones of FFs 1-9 (and to a lesser extent, 10, 11 & 12) was getting the airship. It would be neat if S-E somehow brought that sensation back. I'd like to zip around the world on my own airship. Maybe make it big enough so you can bring a party with you (+7) and there could be flying mobs to take on, like the dragon in FFVI that would sometimes attack you. I'm not sure if other MMOs have had airships as flying mounts, so it could be an original innovation on S-E's part if they decided to go through with it.
