Aetheryte Ticket - Useless

[SongJoohee]

Players in possession of an aetheryte ticket when using Teleport will not incur a gil fee.
This item will be consumed upon use.
1 time use item , after player use it , he will tele w/o any fee . Think bout this item like minion or mount (have to use 1 time usable item for start using mount/minion at all)

I think this is probably most likely, but it contradicts other things in the game like Favorited Locations, Return and the Reduced Rates stuff, so it doesn't seem like it would make sense for it to be that as it makes those mechanics redundant.
