Listen up, Bub.

Weather is a given. Physiological reaction to excessive heat is a given.

What's not a given is airlines' lack of planning to deal these unavoidable statistical realities. These matters can be dealt with albeit not at the maximum profit the airline is trying to extract.

Your poor judgment about this matter is so excessive that it's almost as if you're a troll just trying to get a rise out of otherwise calm, rational people. Thank god you're not actually in charge of anything.
