Its all about optimizing the way you travel an learn to use the reduced and free teleport points to make routes for arriving different areas.
Currently:
My returning point is Gold Saucer as there I need the shortest time to the airships.
My free teleport point is Kugane.
When I travel from one side of the world to the other side, I targe at first the free or reduced points close to the final target and then go on. When returning is on cooldown the housing area is still a cheap alternative.
