There is currently a bug that allows you to instantly mount when you are in the dragonmaw areas (dragon fortress and netherwing ledge) and it gives you the drake to fly around with. This works even if you are in combat.
I don't know if it works for everyone, so I will give the data that may be relevant:
My information:
- 80 gnome affliction warlock
- Currently using a swift blue gryphon (i doubt that the mount matters)
- I have epic flying, but the second highest level
This bug is useful for:
- Netherwing egg farming
- Farming other various things in that area (herbs, ore, etc)
- VERY quickly finishing the quest: The Not-So-Friendly Skies
- Ganking in the air. You can basically attack and do insta-casts as if you were standing on the ground
