Does the ADA Apply to Airlines?

I follow John Fea at the Way of Improvement.  Today he notes the controversy over reclining airplane seats.

He's 6' 8", so naturally he hates flying.

I wonder though--the Americans with Disability Act requires reasonable accommodations for people with disabilities.  Couldn't height, in the context of airplanes, be considered a disability?

Answer: Based on a layman's skim of the ADA text it isn't.  The key thing seems to be this definition of disability:as a condition which  "...substantially limits one or more major life activities of such individual".
