Airlines, 2001 - 2009

A terrorist attack in 2001 and a recession in 2008 have combined to reduce the presence of the airline industry. The New York Times documents the decline:

[W]hen the latest round of capacity cuts takes effect in September, the seats on domestic flights will drop to 66.5 million — down from a peak of about 84 million in 2001 and the lowest September figure since 1984, according to OAG Aviation, which tracks flight schedules....

The industry has also been cutting jobs. In April, the total number of employees at American carriers was 583,030, down from 624,372 in 2007 and more than 24 percent below the peak in May 2001.

Globally, airline employment is also down significantly. The world’s carriers employed 1.48 million people in 2008, the latest figure available from the air transport association, down from 1.71 million in 2000.

I've documented the local (Ontario, California) effects of this decline, but Ontario International Airport obviously isn't the only entity that is affected.
