Hawaiian Airlines is ending its independent operations as it merges with Alaska Airlines, marking the end of its HA callsign after almost 100 years.
The commemorative flight, HA 866, is scheduled to take off in October, and after that, the flight will assume Alaska Airlines' callsign AS.
The historic Hawaiian Airlines code is slated to disappear by around April 2026 as booking and branding begin to consolidate.
This procedural change signifies the end of Hawaiian's independent operations as the company integrates under a single operating certificate.
