Seemingly,
levitate lets me hover in midair. If I'm a
Dragonborn, I can glide up to 30' (average) as a move action.
I can levitate up 20' as a move action and glide forward 30' as another move action. Next turn, I levitate up 20' more (a net gain of 10 vertical distance if counting in 5' increments) and glide forward another 30'. It's a funky sort of flight. I find this notion amusing.
