Well this post is based from the one who told us how to fly in EK and Kalim as a druid, but for the EK you needed to be inscriptor since its required to use the scroll port thing, which im not, so i searched for an alternative way to do it and here it is.
Follow the steps in the other post after setting your hearthstone in westfall inn (it appears to be a building, but it is broken and mounts are usable inside):
1 - Switch to flying form in northrend
2 - Quee for random instance, and enter the instance
3 - Use hearthstone
4 - ???
5 - profit!
Sorry if my english is bad, and after so much time leeching from this site finally i can post something that i hope u find usefull
