I searched and didn't find this bug posted, so if it does end up being a repost then I apologize. Here it goes...
In order for this bug to work you need a 70 druid with at least one of its flight forms. What you do is shapeshift into your flight form in Shattrath and then use the portal to the Isle of Qual'Danas. When your screen loads after you click the portal, you should still be in flight form and able to fly. This does not work in Azeroth, I tried.
This bug is currently working on WoWFusion, but I'm not sure if it is working for others. I think it will though. GOOD LUCK!
