On April 22, 2026, Hawaiian Airlines officially joins the oneworld alliance. That same day, Hawaiian and Alaska Airlines merge onto a single reservation system. The “HA” flight code disappears. All flights switch to the “AS” code — though the planes still carry Hawaiian’s Pualani branding and the in-flight experience stays distinctly Hawaiian.

This is the biggest structural change to Hawaiʻi air travel in years. If you fly Hawaiian regularly, your loyalty program already changed. If you fly other oneworld airlines (American, Qantas, Japan Airlines, British Airways, Cathay Pacific), you just gained a new way to earn and burn miles on Hawaiʻi routes. Here’s what matters.

The HawaiianMiles loyalty program has been replaced by Atmos Rewards, the unified loyalty currency shared with Alaska Airlines. Your existing HawaiianMiles balance converted 1:1 to Atmos Rewards points — no action needed on your end. Points don’t expire. TravelMint

Hawaiian’s Pualani elite status tiers map to corresponding Atmos Rewards tiers. If you held Pualani Gold or Platinum, you should already see equivalent status in your Atmos account. If your status hasn’t synced, contact Hawaiian directly — several travelers have reported delays. The Points Guy

One perk worth flagging: Huakai by Hawaiian members earn a 50% bonus on Atmos Rewards points and status credits when flying neighbor island routes. If you’re island-hopping between Oʻahu, Maui, the Big Island, and Kauaʻi, that bonus adds up fast.

After April 22, anyone with elite status on any oneworld airline gets reciprocal benefits when flying Hawaiian. That means priority check-in and boarding, extra baggage allowances, and lounge access on international routes for top-tier members. Executive Traveller

The reverse works too. Hawaiian loyalists with Atmos Rewards status can use those perks across the entire oneworld network: 14 other airlines, over 1,200 destinations. If you’ve only flown Hawaiian within Hawaiʻi and to the mainland, your status now unlocks benefits on flights to Tokyo, Sydney, London, and everywhere else oneworld reaches.

You can also earn your home airline’s miles when flying Hawaiian. Book a Hawaiian flight, enter your American AAdvantage or Qantas Frequent Flyer number, and the miles credit to your existing account. Same goes for redeeming: oneworld partners can book award seats on Hawaiian metal once the integration is live. One Mile at a Time

April 22 is also when Hawaiian and Alaska move to a single passenger service system. Every Hawaiian flight will carry the “AS” airline code instead of “HA.” If you have an existing booking under the “HA” code for travel after April 22, it should automatically migrate. Check your confirmation email or log into your account to verify.

The brand isn’t going anywhere. Hawaiian Airlines keeps its planes, its crews, its onboard personality. You’ll still get the Pau Hana IPA and the chocolate macadamia nut cookies on transpacific flights. The code change is a back-end system merge, not a brand erasure.

One thing to watch: if you booked through a third-party travel agency or OTA, confirm your reservation transferred correctly. Early reports suggest most bookings migrated smoothly, but a few travelers have flagged missing seat assignments and meal preferences. AwardWallet

Hawaiian is investing $600 million over five years to overhaul its fleet, lounges, and terminals. The headline upgrade: a proper Premium Economy cabin on its Airbus A330 widebodies, replacing the old “Extra Comfort” seats. Think bigger seats with real legroom and upgraded meal service, priced well below business class.

The existing A330 business class is getting refurbished. And Hawaiian is partnering with Starlink to bring reliable, high-speed Wi-Fi to transpacific flights. If you’ve suffered through patchy satellite internet over the Pacific, this is a real upgrade.

These changes roll out over the next couple of years. Don’t expect every plane to have the new cabin configuration by summer 2026 — but some A330s on high-demand routes (LAX-HNL, SFO-OGG) will likely be among the first retrofitted.

The oneworld merger doesn’t directly set fares, but it reshapes competition. Hawaiian and Alaska are no longer competing against each other on overlapping routes — they’re coordinating. That removes a price pressure valve on popular corridors like LAX-HNL and SEA-OGG.

At the same time, jet fuel prices are running 12-18% above last year, and airlines have passed some of that along. Summer 2026 fares to Hawaiʻi are roughly 8-15% higher than summer 2025 across the board.

The counterweight: Southwest, Delta, and United are all pushing capacity on Hawaiʻi routes. Southwest just launched Ontario to Honolulu (June 4) and adds Burbank to Honolulu on August 4. Competition keeps any single carrier from jacking prices unchecked.

Book midweek departures (Tuesday or Wednesday) to save 10-20% over weekend flights. Red-eye departures from the West Coast run $40-$80 cheaper than daytime flights.

If you’re a HawaiianMiles member, log into your Atmos Rewards account now and confirm your points balance and elite status transferred correctly. Screenshot your current status and balance as a reference in case anything gets lost in the system merge.

If you have an existing Hawaiian Airlines booking for travel after April 22, verify the reservation is intact after the code switch. Double-check your seat assignment and any special requests you added at booking.

If you fly American, Qantas, Japan Airlines, or any other oneworld carrier, add your frequent flyer number to any upcoming Hawaiian flights to start earning miles immediately after April 22.

And if you’re still booking summer flights, consider whether the new alliance opens better routing options. Connecting through a oneworld hub on a partner airline might beat a direct flight on price — especially from cities without nonstop Hawaiʻi service.
