Weak analogy: theaters may just break even on admission charges; the money is made at the snack bar. Airlines make money on the fare. Unlike some here, I do not know about this analyst, but a statement like "makes my blood boil" makes him appear to be a jerk (or worse). And, there is the health issue: with reduced humidity aboard, passengers should drink liquids (especially water) to prevent dehydration. Charging for water COULD be considered a risk to health.
