Momote Airport — Manus Island, Papua New Guinea

MAS is Momote Airport, located on Manus Island in Papua New Guinea's Manus Province. The airport has notable World War II history, having been constructed as a military airstrip during the Pacific campaign when Manus served as a major Allied naval and air base. Today MAS provides essential domestic air connections linking the remote island province to Port Moresby, since Manus's island geography makes air travel the primary practical option for residents and visitors. The airport supports government, commercial, and occasional tourism traffic, with Manus also known in recent years for its role in Australia's offshore immigration processing arrangements.
