A joint investment plan with public and private investors in fourteen Kagoshima Prefecture municipalities established Japan Air Commuter.[5] At the time JAC was an affiliate of Toa Domestic Airlines, later known as Japan Air System.[5] Japan Air System later merged into Japan Airlines.
In October 2019, JAC, Japan Airlines, All Nippon Airways, Oriental Air Bridge, and Amakusa Airlines formed Essential Air Service Alliance LLP [ja] (EAS LLP), a limited liability partnership, as an alliance among the three Kyushu regional carriers, with the aim of consolidating safety and technical operations, sales promotions, procurement, personnel, and other functions.[7][8] JAC began code sharing with All Nippon Airways in October 2022, with certain flights carrying both ANA and JAL flight numbers.[3]
JAC joined Oneworld as an affiliate member in October 2020.[9]
