Claim Fly
Lets you fly while you're inside a land claim you own or are trusted in, without needing creative mode. Step outside the claim and flight is taken away automatically.
How It Works
Type /cfly to toggle flight on or off. This toggle doesn't carry over between sessions - it turns back off whenever you rejoin the server, so you'll never end up flying by surprise from an old session.
Once it's on, flight follows you around: as you move into a claim you have build or access rights in, you'll start flying automatically. Walk out of that claim (or lose your trust there) and flying is switched off the moment you leave.
This plays nicely with other ways of flying - if you're already flying from creative mode, spectator mode, or another plugin, claim fly won't interfere with it or take it away. It only ever grants and removes the flight it gave you itself.
Everyone can use this by default, though some servers may restrict it. It only works in claims, so it requires GriefPrevention to be running on the server - if it isn't, the command will let you know it's unavailable.
