If you're near the ground, in the A/C units. Higher up, it's removed in
the atmosphere.

Well, that's my point. Climb and descent aren't long enough to affect
whether one jet is "drier" than another or not. Whatever effect exists, it
would have to happen during cruise. I see no way for such an effect to
exist.
