Complex Systems with Patrick McKenzie (patio11)20 Maalis 2025

Points, profits, and packed planes, with Gary Leff

Patrick McKenzie (patio11) is joined by Gary Leff, the author of "View from the Wing", to discuss the economic systems behind airlines and loyalty programs.

The conversation explores why many irrational airline policies reflect deeper economic realities and competitive constraints that shape flying today.
