First I'd like to point out that you need to have a monk at least level 60 with the Zen Flight Glyph. Didn't see this is any of the other threads, so thought I'd just post it here. Basically, all you need is any(?) transformation buff while you're on your zen cloud(monk only) and fly through a CRZ barrier(AKA spaces between zones). You'll get dismounted, however you keep flying and you're able to cast spells like normal.
