Fly under Northrend in patch 4.0.1

[ihatejunk]

With changes to mounting in the last patch, we have fewer places to get through walls. Though you can no longer mount through the walls, there are still some tricks you can use to get through them. Jumping right as you mount in a tight spot is still a viable glitch. Here is a spot in Northrend that you can still get through to fly around underneath.

Not sure if this still works or not, but it worked then, and you cared enough to make a video. +Rep from me.
