Fly

Units entirely with Fly ignore Terrain Features, Open Terrain and other units during Move Manoeuvres and Charge Moves.
The unit must follow the Unit Spacing rule at the end of any of its moves, and Terrain Features and Open Terrain from which the model starts or ends its move still affect it.
The charged unit is not ignored during a Charge Move, and there must be room for the unit’s Front Facing to be placed in contact with the charged unit before the Initial Align Move.
