I dunno if this has been posted yet but since they hot fixed the flying exploit I had to find a new way to get to the hyjal fishing spot.
Easiest way.... Die, get on the mount. While dead head left and fly around the mountain down to the fishing spot. From there work your way back checking where you can land safely without being ported. Take notes of landing spots every 30 or so feet.
You can still rez and have the flying mount for 6 seconds.
So from your starting point at the base of the mountain die.... Run into hyjal, fly to your body. Fly up as far as you can to accept rez.
When you accept, immediately fly up as high as you can while moving above your next landing spot so you fall down and die at that spot (unless you can kill yourself like a lock, you can cut down the amount of stops you have to make).
Rinse and repeat until you eventually make it to the fishing spot. Locks can do it in about 3 to 4 step... Classes that can't kill themselves can make it in about 4/5 steps.
