Okuma airframes and spare spools

I just tried out my brand-new Okuma Airframe 4/6. For the price - $35 -
these reels are oustanding. I especially like the soft wris****ch-like ticks
they make on line-out, a long way from the peace-busting ratcheting of my
first fly reel. And the drag wheel's large and easy to set, without being
obtrusive.

Question: Does Okuma offer spare spools for the Airframes? If so, who
carries them? I've done a search, and spare spools seem to be available for
the other Okuma reels, but not the Airframe.

Thanks.
