Voidal Resonator should be a flying mount.

[Vejjiegirl]

I was going on about seeing him in Haukke Manor, from that he doesn't look like he'll be able to take us to the heights he needs to take us .

You quoted me pretty fast, that was more for everyone in the topic though.

Chocobos are built like ostriches and shouldn't be capable of flight, yet they will be in Heavensward. I don't see why the same wouldn't be possible for the resonator.

Not just regular chocobos there is a high chance we are getting a Fat chocobo flying mount, reference the past interviews with Yoshi-P.
The fact that we will be able to fly on a fat chocobo kind of throws everyone's Ahriman's flight restrictions speculations out the window, anything is possible!

Even Gizamaluke!!!

(Taken from the Benchmark, I hope its Gizamaluke!)

To add to my point:
The Ahriman's second appearance was in Final Fantasy 4. In FF4 they fought Cecil on airships above the clouds (The Red Wings)
