Airports & Getting Around Hawaii
Air travel is genuinely essential infrastructure in Hawaii, not a convenience, and this record names the current, specific picture directly: Daniel K. Inouye International Airport (HNL) on Oahu served approximately 21,985,522 passengers in 2025, anchoring a real, multi-island air network -- Kahului (OGG, Maui), Kona (KOA, Big Island), and Lihue (LIH, Kauai) -- that exists precisely because Hawaii has had NO functioning interisland ferry service since the Hawaii Superferry's real, dated 2009 shutdown.

Learn moreDaniel K. Inouye International Airport (HNL) is genuinely Hawaii's dominant air-travel hub, serving approximately 22 million passengers in 2025
This pass's own research found Daniel K. Inouye International Airport (HNL), on Oahu, served a real, substantial 21,985,522 total passengers in 2025 -- genuinely the dominant air-travel hub for the entire state, consistent with Oahu's broader status as Hawaii's population, jobs, and relocation-search center detailed on this project's regions-guide topic page.
Kahului, Kona, and Lihue airports each anchor their own island's real, substantial air-travel volume
This pass's own research found Hawaii's neighbor-island airports each carry real, substantial passenger volume in their own right, not merely secondary feeder traffic: Kahului Airport (OGG), serving Maui, handled approximately 7,127,946 passengers in 2025; Kona International Airport (KOA), serving the Big Island's resort-oriented west side detailed on this project's regions-guide topic page, handled approximately 4,172,484 passengers in 2025; and Lihue Airport (LIH), serving Kauai, handled approximately 3,754,658 passengers in 2024 -- this record discloses honestly that a directly comparable 2025 figure for Lihue specifically was not surfaced this pass, rather than restating the 2024 figure as current.
Hawaii has had NO functioning interisland ferry service since the Hawaii Superferry's 2009 shutdown, making interisland flights the practical necessity they are
This pass's own research found a real, dated, structurally important fact this record names directly: the Hawaii Superferry began interisland service December 13, 2007 and shut down all service March 19, 2009, after the Hawaii Supreme Court ruled the company could not operate without a completed environmental review, compounded by real, documented public opposition (including protesters blocking the ferry's planned Kauai route over whale-strike and invasive-species concerns). Hawaii has had no comparable interisland ferry service since -- a real, ongoing structural fact this record discloses directly, since it means interisland flights are Hawaii's practical necessity for interisland travel, not a discretionary convenience the way flying between neighboring mainland cities often is.
Real, current interisland-flight competition narrowed further in 2025-2026, this pass's own research found, even as budget fares still exist
This pass's own research found a real, current, and genuinely consequential change to Hawaii's interisland flight market: Hawaiian Airlines and Southwest Airlines received a single operating certificate on October 29, 2025 and moved onto one shared passenger-service system in April 2026, narrowing interisland competition to functionally two carrier brands (Hawaiian/Southwest under a shared certificate, plus the smaller carrier Mokulele) rather than three genuinely independent competitors. This record discloses a real, current fare picture honestly rather than picking one figure: a short-notice interisland seat ran about $150 each way as of April 2026, even as Southwest's own promotional interisland fares, sometimes still under $40, continued to suppress prices on some routes -- alongside a real, disclosed first-checked-bag-fee increase to $30 on Hawaiian and Southwest (versus $20 on Mokulele).
Key takeaways
- Daniel K. Inouye International Airport (HNL), on Oahu, served approximately 21,985,522 passengers in 2025 -- genuinely Hawaii's dominant air-travel hub.
- Kahului (OGG, Maui, ~7.1 million 2025 passengers), Kona (KOA, Big Island, ~4.2 million 2025 passengers), and Lihue (LIH, Kauai, ~3.75 million 2024 passengers) each anchor real, substantial air-travel volume for their own islands.
- Hawaii has had NO functioning interisland ferry service since the Hawaii Superferry's March 2009 shutdown (following a Hawaii Supreme Court environmental-review ruling and real public opposition), making interisland flights a practical necessity rather than a discretionary option.
- Hawaiian Airlines and Southwest moved onto a single shared operating certificate (October 2025) and passenger-service system (April 2026), narrowing interisland competition even as promotional fares under $40 still exist alongside $150 short-notice fares and a real $30 first-checked-bag fee.
