InterIsland Air was a commuter airline based in Kahului, Maui, that operated scheduled and charter services among the Hawaiian Islands from the late 1990s until operations were suspended in 2017. The carrier served short-haul markets linking Maui with Oʻahu, Hawaiʻi (the Big Island), and smaller destinations, operating in the competitive regional market alongside airlines such as Hawaiian Airlines, Mokulele Airlines, Island Air (Hawaii), and Go! (airline). Its operations intersected with regional aviation infrastructure at Kahului Airport, Daniel K. Inouye International Airport, and community airfields including Hilo International Airport and Lihue Airport.

History

InterIsland Air was founded in 1997 by local entrepreneur Daniel Inouye II and established as a niche commuter service to supplement interisland connectivity, competing with legacy carriers like Aloha Airlines and emergent operators such as Independence Air. The airline expanded during periods of market disruption, including after the bankruptcy of Aloha Airlines (1946–2008), and faced regulatory oversight from the Federal Aviation Administration and financial scrutiny tied to fluctuating fuel prices and aircraft leasing markets dominated by lessors such as GE Capital Aviation Services. In the mid-2000s InterIsland Air adjusted schedules in response to route realignments by Hawaiian Airlines and codeshare strategies by major carriers. Legal and operational challenges culminated in suspension of scheduled services in 2017 amid pilot recruitment constraints and certification issues overseen by the United States Department of Transportation.

Operations

InterIsland Air operated primarily short-haul scheduled flights and on-demand charters, focusing on point-to-point service rather than hub-and-spoke networks used by carriers such as United Airlines and Delta Air Lines. Its business model emphasized frequency on thin routes connecting regional airports like Kapalua Airport, Waimea–Kohala Airport, and Molokai Airport with Maui and Oʻahu. Ground operations coordinated with airport authorities at Haleakalā-adjacent facilities and relied on maintenance partnerships with providers experienced in regional turboprop support, including firms that also serviced fleets for PenAir and Silver Airways. The carrier's ticketing and sales interfaces interacted with distribution systems influenced by Sabre Corporation and local travel agencies servicing destination markets dominated by tourism from regions such as Japan and California.

Fleet

InterIsland Air's fleet consisted mainly of small turboprop aircraft optimized for short runway performance and frequent rotations. Types operated included models comparable to the Dornier 228 and light commuter aircraft similar to the Cessna 208 Caravan, reflecting common regional use by operators like Ameriflight and Cape Air. Aircraft procurement and leasing were affected by secondary markets involving companies such as AAR Corp. and Boeing Capital Corporation. Maintenance programs followed practices outlined by the Federal Aviation Regulations and were performed at line stations across Hawaiian airports, with airframe inspections often coordinated during overnight rotations to minimize disruption to service.

Destinations

The carrier served interisland destinations across the Hawaiian archipelago, linking primary airports such as Kahului Airport and Daniel K. Inouye International Airport with secondary fields including Lihue Airport, Hilo International Airport, Kona International Airport at Keāhole, Hoolehua Airport, and Kalaupapa Airport. Routes targeted both resident travel and visitor flows to resort regions on Maui, Kauaʻi, and the Big Island of Hawaii, often complementing ferry services and ground transfers connected to resorts and government sites like Haleakalā National Park. Seasonal adjustments mirrored demand spikes tied to events such as the Maui County Fair and holiday travel periods to and from source markets including Honolulu and Kahului.

Safety and Incidents

InterIsland Air operated within the safety oversight frameworks administered by the Federal Aviation Administration and was subject to inspections and audits similar to those applied to regional operators such as Peninsula Airways and Island Air. Notable incidents included mechanical issues and ground handling occurrences typical of turboprop operations; investigations, when initiated, involved agencies like the National Transportation Safety Board for any significant events. Safety management practices evolved in response to industry best practices promulgated by organizations such as the International Civil Aviation Organization and were influenced by accident-prevention programs adopted across the commuter airline sector after high-profile occurrences involving carriers such as Comair.

Corporate Affairs

Ownership and finance for InterIsland Air were locally oriented, with investment and management drawn from Hawaiian business networks and occasional outside investors active in regional aviation finance. Corporate governance intersected with regulators including the United States Department of Transportation for economic authority and the Federal Aviation Administration for air carrier certification. Labor relations and pilot recruitment mirrored challenges faced broadly in the regional industry, where competition with airlines like Hawaiian Airlines and mainland carriers affected pilot supply. Strategic considerations included potential partnerships or code-share arrangements—common in relationships among airlines such as Alaska Airlines and regional affiliates—but sustained consolidation pressures reshaped the Hawaiian interisland market through the 2000s and 2010s.

Community and Cultural Impact

InterIsland Air played a role in local mobility and tourism, supporting connections that underpinned events and economic activity across islands such as Maui, Kauaʻi, and the Island of Hawaii. The carrier interfaced with cultural institutions and festivals, facilitating travel to celebrations tied to Hawaiian heritage and sites like Iolani Palace and Puʻuhonua o Hōnaunau National Historical Park through increased visitor access. Its operations affected island communities, emergency medical transport capabilities, and small-business tourism ecosystems that also welcomed visitors from source markets including Japan, Australia, and the Contiguous United States. The legacy of InterIsland Air continues in discussions about regional connectivity, tourism resilience, and local entrepreneurship in Hawaiian aviation.
