I flew over Wintergrasp extensively, farming for ore to level engineering. They opened up flying there without getting dismounted (in between battles) some time ago. However, I did find a couple of spots near the edge, particularly close to the keep on the Alliance side, where there seems to be a pocket that dismounts you. I don't believe this is intentional, merely a glitch. I've noticed a spot in Dalaran, over Thread of Fate, I believe, that does the same. I believe the game simply reads that area as being inside a building, even though you are not, and dismounts you.
