Nov. 2009 Air Transport Data
The U.S. Department of Transportation has released its data on air transportation for November 2009. The key metric that I focus on in this release is system revenue passenger miles (SRPM). I focus on SRPM because it is a good leading indicator for aerospace industrial production. SRPM is calculated by multiplying the number of revenue generating passengers on a flight times the number of miles the flight travels. In November 2009, SRPM was a little more than 59 million passenger miles. This was an increase of 1.02% compared to November 2008. This was only the second time that SRPM grew month over month since March 2008.
