WOW: Flying in Azeroth with the Blizzcon bear

Required:
The Big Blizzard Bear

This glitch allows you to fly in Azeroth, including everywhere in Orgrimmar. Mount on one the Big Blizzard Bear and walk into the Dragonmaw Fortress until you have both the mount buff, and the Dragonmaw Nether Drake buff.

Then, fly directly into Shattarath, and ground yourself whilst staying on your mount. Now enter the Orgrimmar portal, and you should be able to fly everywhere! Make sure not to enter the building below the portal entrance, or you will be dismounted. Hop over the edge.
