Summary
Hawaiian Airlines is replacing its aging interisland Boeing 717 fleet with larger Boeing 737-800 aircraft, doubling first-class seats and adding more than 30 Premium Class seats per plane. The first aircraft begins three daily Honolulu–Kahului round trips this October, with every seat offering free Starlink Wi-Fi, in-seat power, and USB charging.
The full fleet transition won’t begin until 2028, but the initial October deployment immediately improves premium-cabin availability on Hawaii’s busiest interisland corridor. Watch for the schedule release to lock in first-class award space before peak winter travel dates.
The Boeing 717 has been the backbone of Hawaiian Airlines’ interisland network since 2001—a reliable workhorse whose age and cabin limitations have become an increasingly conspicuous drag on the passenger experience. That era is ending. Alaska Air Group confirmed the neighbor island fleet will transition to Hawaiian-branded Boeing 737-800 aircraft, bringing a generational leap in comfort, connectivity, and premium-seat supply to the carrier’s most essential routes.
The first tangible change arrives this October, when a single Alaska Airlines-liveried 737-800 begins operating three daily round trips between Honolulu (HNL) and Kahului (OGG) from Terminal 1. This capacity supplement doubles first-class seating and injects more than 30 additional Premium Class seats into Hawaii’s highest-density interisland corridor—a route where upgrade inventory has historically evaporated weeks before departure.
Every seat on the new aircraft gets fast, free Starlink satellite Wi-Fi, a 110V power outlet, USB charging, and a seatback device holder. The leather Recaro seats recline, addressing one of the most frequent complaints about the 717’s tired cabins. For surfers and residents hauling oversized gear, the 737-800 also provides increased cargo capacity.
Once the full transition is complete, the fleet remains Hawaiian-branded, based in Honolulu, and flown by Honolulu-based pilots and flight attendants. The inflight product, however, will finally match the expectations of travelers connecting through the islands on premium itineraries.
The cabin upgrade, by the numbers
The carrier’s regulatory filing confirms the 737-800s will carry twice as many first-class seats as the outgoing 717, alongside more than 30 additional Premium Class positions. While exact seat counts remain under wraps pending the final configuration reveal, the directional shift is unambiguous: interisland premium supply is about to expand materially, and the Honolulu–Kahului corridor gets the first tranche of that inventory starting in October.
| Date | Event | Impact | Status |
|---|---|---|---|
| October 2026 | One Alaska-branded 737-800 begins HNL–OGG service | Doubled first class, 30+ extra Premium Class seats | Confirmed |
| 2028 | Full 737-800 fleet transition begins | Network-wide premium seat expansion | Announced |
| TBD | Hawaiian-branded 737-800s enter service | Consistent premium product across interisland network | Pending |
| TBD | Starlink activation on interisland fleet | Free gate-to-gate high-speed connectivity | Pending confirmation |
The verified announcement, published through Alaska Air Group’s investor channels, confirms Honolulu-based crews will operate the aircraft under the Hawaiian brand once integration completes. The filing also notes the 737-800’s cargo hold capacity improvement—a practical benefit for surfboard transport that the 717 struggled to accommodate.

Why this matters beyond seat counts
Interisland premium cabins have been among the most upgrade-resistant products in the U.S. market. The 717’s eight first-class seats meant that even top-tier elites often cleared upgrades only on off-peak midweek flights. Doubling that inventory doesn’t just improve odds on the initial HNL–OGG rotations—it rewrites the calculus for anyone routing through Honolulu on a multi-island itinerary booked with miles.
Hawaiian Airlines’ April 2026 entry into the oneworld alliance compounds the strategic value. Alaska and American Airlines elites now have reciprocal upgrade and award-booking pathways across Hawaiian’s network. More premium seats on the interisland backbone means oneworld Sapphire and Emerald members connecting from long-haul partners like Japan Airlines or Qantas will find meaningfully better availability on the island-hopping segments that complete premium itineraries. For a deep dive on alliance implications, Air Traveler Club’s oneworld integration analysis covers the reciprocal benefit structure in detail.
Locking in the October capacity boost
The October HNL–OGG deployment is a capacity supplement, not the full fleet swap—which means premium inventory on that specific corridor will improve first, while other interisland routes continue on 717s until 2028. For elite members and award travelers, the window to act opens as soon as October schedules are published.
- Check both booking channels immediately. Hawaiian Airlines and Alaska Airlines each retail interisland tickets. Compare cash fares and award pricing across both once the 737-800 schedule loads, since loyalty program integration means inventory may display differently on each platform.
- Prioritize HNL–OGG for upgrade instruments. If you hold Alaska elite upgrade certificates or HawaiianMiles upgrade awards, the Honolulu–Kahului corridor offers the best clearance odds in the near term simply because there are more seats to clear into.
- Winter peak will still be tight. The added premium inventory helps, but Hawaii’s holiday and February high-season demand will continue to pressure availability. Book award seats the day schedules open if you’re traveling between mid-December and March.
- Expect Starlink to be a quiet differentiator. United’s own Starlink rollout has proven that free, fast Wi-Fi changes passenger behavior on short-haul segments. Hawaiian’s interisland product suddenly becomes the best-connected option in the market.
Watch for two signals in the coming months: first, the October schedule publication confirming aircraft assignments and seat maps; second, any announcement of the full cabin configuration with exact dimensions and first-class specifications. Both will clarify how competitive this product is against the broader domestic narrowbody landscape.
FAQ
When can I book the new 737-800 interisland flights?
The October Honolulu–Kahului schedule should appear in Hawaiian and Alaska booking engines in the coming weeks. Exact timing depends on when the airline loads the new inventory, but watch both platforms for the three daily round trips operating from Terminal 1 at HNL.
Will Starlink Wi-Fi be available on day one of 737 service?
The airline has confirmed Starlink will be installed but hasn’t specified an activation date. United’s experience suggests Starlink can be operational from the first day of service on newly configured aircraft, though Hawaiian’s timeline hasn’t been published definitively.
How many first-class seats will the 737-800 actually have?
The precise seat count hasn’t been released. Alaska’s announcement confirms “twice as many” as the 717’s eight first-class seats—implying 16—but the final configuration may vary. Official seat maps will clarify once published.
