- Hawaiian Airlines officially retired its HA code on April 22, 2026, transitioning to Alaska’s AS prefix.
- The shift follows a successful system migration to the Sabre platform, aligning both carriers’ reservation systems.
- Passengers will see AS prefixes on tickets, though Hawaiian’s branding, crew, and aircraft remain unchanged.
(HONOLULU, HAWAII) — Hawaiian Airlines has retired its HA flight code, and every Hawaiian flight now appears under Alaska Airlines’ AS code. The change took effect on April 22, 2026, and passengers booking new travel will see the new prefix on tickets, reservations, and flight listings.
The shift is the clearest sign yet that Alaska Air Group has folded Hawaiian deeper into its own systems after the $1.9 billion acquisition announced in September 2024. Travelers who booked before the change still have valid HA tickets. The aircraft, crew, and island-focused service remain in place.
The old code had been part of Hawaiian flying for 97 years. Its retirement became possible after Hawaiian moved its Passenger Service System from Amadeus to Sabre overnight on April 21, 2026, matching Alaska’s reservation platform. That move completed the back-end work needed to put all Hawaiian flights under the AS prefix.
Here is the basic timeline behind the transition:
| Milestone | Date |
|---|---|
| Alaska Air Group acquisition | September 2024 |
| Temporary flight-number range begins | October 26, 2025 |
| Passenger Service System migration | April 21, 2026 |
| HA code retired | April 22, 2026 |
| Last HA flights departed | April 20, 2026 |
During the transition period, Hawaiian used a temporary numbering range from HA800 through HA1299 to avoid conflicts with Alaska’s existing flight numbers. That temporary step ended once the new reservation platform was in place and the HA code was removed.
Flight listings now show the AS prefix across tickets and reservations. A Honolulu to Pago Pago flight that used to appear as HA865 now shows as AS865. Existing bookings made before April 22, 2026 still display the old code and remain valid.
The practical effect for travelers is narrow but important. A new booking made today for a Hawaiian-operated flight will show AS, even though the aircraft is still flying under the Hawaiian Airlines brand. Someone who already bought a ticket before the switchover does not need to change anything. The same flight, same seat, and same crew are still operating.
Hawaiian’s brand has not disappeared. The airline still flies under the Hawaiian Airlines name, keeps its crew, and continues interisland operations. Its Pualani tail logo remains visible on the aircraft and across digital channels, and the company still presents the same Hawaiian hospitality message that has defined the carrier for decades.
That distinction matters because airline code changes often create confusion at the ticketing stage. Here, the code changed, but the product did not. Travelers booking through Hawaiian or Alaska will see the new AS identifier, while the onboard experience remains tied to Hawaiian’s aircraft and service model.
Loyalty members should also watch how the two programs continue to converge. The code change sits inside a broader integration between Hawaiian and Alaska, and that usually means tighter alignment on booking, check-in, and future mileage earning rules. Alaska Mileage Plan already sits at the center of the combined operation, so travelers looking for redemption value should check both award pricing and route options before booking.
Competitive pressure in the Pacific has been building for years. United, Delta, and American all compete heavily on Hawaii routes, and code changes like this one signal how seriously Alaska is treating its expanded footprint. The result is a more unified network on the back end, even if the front-end branding still looks and feels Hawaiian.
Alaska Air Group’s purchase of Hawaiian gave it a stronger position in transpacific flying and in the interisland market. The Sabre migration now places Hawaiian on the same reservation platform as Alaska, which should make future schedule changes, through-ticketing, and customer-service handling easier inside the combined group.
Travelers with upcoming trips should check their confirmation emails and boarding passes before departure. Bookings made before April 22, 2026 can still show HA, while new reservations will show AS. The code is different; the flight itself is still Hawaiian Airlines-operated.
If a Hawaiian trip is on the calendar, the key date is already here. New reservations now show AS, and the old HA prefix has left the system for good.
