The readers always write. Comments and questions from the customers, edited to fit this space. A column about easing congestion in the airways advocated, among other things, congestion pricing. That is, air fares during popular travel times should cost more. It brought this response.
Congestion pricing is alive and well at every single airline.
I don't know of anyone who calls it that, but that is exactly what yield management is all about. Having an abundance of cheaper fares on those off-peak days draws discretionary demand away from the peak flights where most seats sell at full coach fares. Thus, while the fares are technically the same all the time, the availability is the key. And those higher fares tend to control demand on those peak flights to a manageable level. I never thought of it that way.
