Aviation
Despite the effects of the recent recession, commercial flights were about 33 million higher in number in 2011 than in 2000, stretching the system’s ability to meet the needs of the nation’s economy. The Federal Aviation Administration (FAA) estimates that the national cost of airport congestion and delays was almost $22 billion in 2012. If current federal funding levels are maintained, the FAA anticipates that the cost of congestion and delays to the economy will rise from $34 billion in 2020 to $63 billion by 2040.
