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.

Port Moresby, also referred to as Pom City or simply Moresby, is the capital and largest city of Papua New Guinea. It is one of the largest cities in the southwestern Pacific outside of Australia and New Zealand. It is located on the shores of the Gulf of Papua, on the south-western coast of the Papuan Peninsula of the island of New Guinea. The city emerged as a trade centre in the second half of the 19th century. During World War II, it was a prime objective for conquest by the Imperial Japanese forces during 1942–43 as a staging point and air base to cut off Australia from Southeast Asia and the Americas.
