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.
