Portland International Jetport (IATA: PWM, ICAO: KPWM, FAA LID: PWM) is a public airport located two miles (3 km) west of the central business district of Portland, in Cumberland County, Maine, United States. It is owned by the city of Portland. A significant portion of the Jetport, including the main runway, is located in the neighboring city of South Portland.
This regional airport serves much of Maine and is the busiest airport in the state. In 2007, the airport handled a record 1.6 million passengers, up 17.0% from the previous year, and is on track to handle 1.8 million passengers in 2011. In recent years, the Jetport has benefited from service by low-cost carriers such as AirTran Airways and JetBlue. A survey conducted in June 2011 found PWM to be the most affordable airport in the region, and the third most affordable in New England.
In October 2011, PWM completed a $75 million renovation and expansion of its terminal to allow more airline service and more amenities for passengers. The current airport started to take shape in the 1950s to '60s. Runway 11/29 was built in 1957 and lengthened to 6,800 feet (2,073 m) in 1966. The current terminal was opened in 1968, when jet service began.
