Q&A for How to Fly in World of Warcraft

Some zones have flying restrictions, that might be the problem. Try flying in your capital (Stormwind for Alliance and Ogrimmar for Horde).

Using the default keybinds: Press "Shift +P" to open up your collections window. Then, click the "Mounts" tab to see all your mounts. You can drag one of those to an action slot on your window so you can click it to mount, or you can drag the "Random Mount" icon that's in the top left corner of the window to an action slot so you can summon a random mount when you want to fly. Once you're on a flying mount (in the "Mount Collection" window, you can select filters for "Ground" "Swimming/Water" or "Flying" mount ) press the Spacebar to tilt up and X to tilt down.

That's a PVP area, so there is no flying there. You can learn to fly in Stormwind or Orgrimarr.

If you're talking about Crystalsong Dalaran, yes, you can fly there.
