For large airships, unless stored indoors (which is of course hard because of the size of the structure required) they are essentially permanently in flight. The Goodyear blimps, for example, are followed as they travel by portable (truck-mounted) mooring towers but must have pilots on board 24/7 even when moored, because a modest wind can easily blow the mooring tower over if pilots don't maneuver the ship "on the ground." In high winds mooring is simply impossible and the airships must remain aloft. The logistics of this operation are very complex, and the airship must be able to swing 360 degrees while moored to allow for maneuvering, which requires a huge area. The result is that the Goodyear blimps rely on a pretty limited set of mostly small municipal airports that they have experience with. Closed air force bases are popular since they're most likely to have a far corner of the tarmac that the trucks can easily drive out to but that has no structures or other aircraft use that the airship would interfere with. The Goodyear website has a picture that gives you a good idea of what this looks like: https://www.goodyearblimp.com/behind-the-scenes/img/emeablim...
Not pictured is the truck of helium cylinders that accompanies the blimp for top-ups, which are required as I understand it mostly due to leakage, as the pilots carefully avoid venting helium due to the high cost (it's an option for emergencies).

Airships are huge and hard to manage.
