Hawaiian Airlines is finally getting a proper premium refresh, and it's happening on the aircraft that matters most for long-haul flyers: the Airbus A330. Under parent company Alaska Air Group, Hawaiian will reconfigure all 24 of its A330-200s with four cabin classes by 2028, centred on a brand-new flagship product called the Leihoku Suites.

The front cabin gets 22 lie-flat suites with sliding doors in a 1-2-1 layout, replacing the current 18 business seats squeezed into a 2-2-2 arrangement. Each suite comes with a 19-inch 4K screen, chef-designed dining with wine pairings, hotel-quality bedding and Starlink WiFi for Atmos Rewards members. Dedicated check-in and concierge services will run in Honolulu and Seattle. Behind that sits a 'Premium Reserve' cabin — effectively domestic business class — with 38 inches of pitch and 16-inch OLED screens, plus 204 economy seats with new 13-inch 4K displays. The reconfiguration trades four economy seats for 12 premium ones. A new 200-guest lounge at Honolulu's Terminal 1 is slated for early 2028.

Not everything is being touched. The 19-strong Boeing 717 fleet that hops between the islands is heading for retirement from 2028, replaced by second-hand 737-800s transferred from Alaska. Those jets will carry an Alaska-style interior with 16 reclining Recaro first-class seats rather than Hawaiian's new look. Hawaiian and Delta are now the last passenger airlines flying the 717, a type with McDonnell Douglas roots that has become costly to maintain and thirsty at the pump.

The bigger question mark hangs over the 18 A321neos — Hawaiian's newest aircraft at an average age of seven years. Alaska's CFO has said the fleet will either double in size or be phased out entirely, with a decision expected around 2027-2028. Executives reportedly feel 18 jets is too small a subfleet to justify permanently, especially since Alaska runs an all-Boeing maintenance operation. If retained, the fleet would grow to 30-40 aircraft to make economic sense; if retired, the stretched 737 MAX 10 could step in on thinner mainland routes. There's also a wildcard: the A321XLR could theoretically unlock routes like Honolulu to Chicago, Auckland or Fukuoka. Complicating everything, Alaska took over Hawaiian's 12 Boeing 787-9 order for its own long-haul network, leaving the A330s as Hawaiian's widebody workhorse for now.

Why should travellers care? If you fly Hawaii from the mainland or beyond, the premium cabin on offer is about to jump a generation — real closed-door suites on routes where they previously didn't exist. Economy passengers benefit indirectly too: Hawaiian argues that premium revenue takes pressure off back-of-cabin fares. The catch is timing — the full experience lands by 2028, and interisland flyers on 737-800s will see a more modest product. Book the A330 if the suite experience is what you're after, and keep an eye on what happens to the A321neos, since it will shape which mainland routes get what aircraft.
