This exploit is a bannable offense, but when people ask you how you do it, and you simply say "I lagged at the flight path" they accept it and carry on. I have been doing this for days straight as a human warlock riding around horde cities while flagged, ironically recieving alot of cheers and waves. Anyways, using that lag excuse seems to satisfy anyone who asks and I have not been reported yet.
There is one thing I would like to point out as well, while taking the zeppelin from Orgrimmar to UC, I got dismounted from the griffon when the world map went off so a heads up on that. I havent tried it on the alliance ships but I imagine its the same.
