Phase Shift in Air Travel Heat Map

By Paul Kedrosky · Sunday, October 11, 2009 ·

Nifty heat map of the phase shift in U.S. travel pre/post 9-11. Notice how planes went from red (prone to delays) to more green (less prone) and stayed that way well into 2007-08. Now, of course, we’re back to limited delays again, thanks to the great recession.
