Pohnpei International Airport (IATA: PNI, ICAO: PTPN) is an airport serving Pohnpei, Federated States of Micronesia. It is located on Deketik, an islet connected to Pohnpei Island by a causeway. It is close to Palikir, the capital of the Federated States of Micronesia. The extension of the Pohnpei International Airport began in 2009 and was to be completed in 2011. The Government of Japan has agreed to provide about US$29 million for the project. The project includes extending the runway by 228 m and improving the terminal facilities and apron. Enhancements will help prevent problems such as when a Boeing 727 cargo jet overran the runway and the airport had to be closed for six days in May 2008.
