The early 21st century headlines regarding the ailing fortunes of Pittsburgh International Airport (PIT) are well known. The financial woes afflicting USAirways, at the time, PIT’s major hub carrier, and its eventual bankruptcy led to an enormous drop in flights with an accompanying drop in passenger count as connecting travel plummeted.
In 2000, PIT was the 25th busiest U.S. airport with 8.65 million enplanements. Note that the Bureau of Transportation Statistics ranks airports by the number of enplanements. Passenger enplanements (all figures rounded to the nearest hundredth) began a steep slide over the next five years, falling to just 5.08 million enplanements in 2005, ranking PIT 40th in the nation.
