This may not have been explained adequately in the anime (or perhaps I just have a knack for not paying attention). Firstly, note that Fei was an earth wyrm, not an earth dragon, and this series makes a distinction between these, as a dragon is a more evolved form (which Fei may reach someday). Now, for the answer.

Fei is able to fly because she evolves into a light wyrm. This is a special evolution that becomes available to her because she's the hero's familiar. From the light novels, volume 3, chapter S6: *Hiding*:

Though Shun doesn't notice at first, he also figures out Fei has a hard time flying straight since her Flight is still level 1, after he tells her to fly straight at an enemy:
