I finally got around to reading the January SKY magazine. Here's an extract from Richard Anderson's editorial:

...Congress again is proposing an increase in passenger facility charges from the current $4.50 to $7 per flight segment. This increase means airline customers would pay an additional $2 billion in taxes per year - an average of $112 per trip for a family of four.

Let's see: at $2.50 per segment, $112 is 44 segments, or 11 segments per person. The average trip has 5 segments each way?

And you wonder why the airline industry is so troubled...

It reminds me of the SKY magazine editorial a few years ago where tarmac delays in ATL were blamed on all the bizjets there.
