Marshall Islands International Airport — Majuro Atoll, Marshall Islands

Marshall Islands International Airport, coded MAJ and also known as Amata Kabua International Airport, sits on Majuro Atoll, the capital and most populous atoll of a remote Pacific island nation scattered across a vast expanse of ocean roughly midway between Hawaii and Australia. Like the rest of the Marshall Islands, Majuro is a narrow ring of coral islets surrounding a lagoon, and the airport's single runway occupies nearly the entire width of the land available at that point, with ocean visible on both sides during landing. The islands played a significant role in the Pacific theater of the Second World War and later served as a site for American nuclear testing at Bikini and Enewetak atolls, a legacy that still shapes the country's relationship with the United States. MAJ functions as the principal air link connecting this isolated nation to Honolulu and other Pacific hubs, a lifeline made more urgent by the islands' extreme vulnerability to rising sea levels.
