With the latest update of the Burning Crusade Alpha Client a new Spell has been introduced.
Flight Form
Shapeshift
Requires Level 68
Self20 Mana
3.000 sec cast
Transforms the Druid into Flight Form. While in this form you are able to fly in Outland. The act of shapeshifting frees the caster of Polymorph and Movement Impairing effects.
I found it here at the Curse Gaming Spell Database.
