Fly in claims means /fly is only usable inside land you own or are trusted in through a claim system like GriefPrevention and similar. Step outside the boundary and you are back to normal survival movement, so the overworld stays grounded while your base becomes a workable space.
The big change is build pace. Roofs, megabase interiors, redstone ceilings, and terraforming stop being ladder-and-scaffold wars. Regular players can take on tall builds and large farms without turning every project into a time sink, and shared areas get maintained more often because access is painless.
It lands between pure survival and creative convenience: you still grind resources, risk your gear, and travel normally, but home feels like a workshop. When it is done right, flight is a home-field perk, not an escape button, with combat timers and border rules that keep chasing, raiding pressure, and general fairness intact.
