Where is everybody?

On what is supposed to be one of the busiest travel days of the year -- I wonder if you folks out there are experiencing what I experienced yesterday as I traveled back to the Worldwide Headquarters.
That experience? A plane that was just a little over half full.
I've received a number of notes today from folks -- all of whom have either commented that the airports at which they work are busy -- but not that busy -- or that planes that have been flown on have not been packed.
Great if we look at this from a passenger standpoint.
Not so great for those of us who know what this means to the airline industry's revenue numbers for the month.
