Port Moresby International Airport, also known as Jacksons International Airport, is an international airport located eight kilometres outside Port Moresby in Papua New Guinea. It is the largest and busiest airport in Papua New Guinea, with an estimated 1.4 million passengers using the airport in 2015, and is the main hub for Air Niugini, the national airline of Papua New Guinea. The airport serves as the main hub for PNG Air and Travel Air. It replaced the original Port Moresby airport, in what is now the suburb of Waigani, whose airstrip remained until the 1990s but no trace of which remains, having been built over.
