Transportation
The Qiannan Libo Airport, opened in late 2007, has capacity to receive planes of the Boeing 737 class, and to handle up to 220,000 passengers annually. However, the $57-million facility is rather underutilized so far. According to the Civil Aviation Administration of China (CAAC) statistics, 151 paying passengers flew into or out of the airport in 2009 - which was a 98% drop compared to the previous year (7886 passengers), and placed the airport the last in list of the nation's 166 airports by traffic volume. Currently four airlines use the airport.
