There has been a small resurgence in the last couple of decades of airships / zeppelins typically using Helium instead of the Hydrogen used in the olden days.
So I'm sure there must be plenty of places where you can do a joyflight or sightseeing loop and come back where you started.
But are there any places in the world where an airship / zeppelin is used for actual travel where you get on at one point and disembark at another?
(Extra points if the trip crosses international borders, large bodies of water, or both!)
