Alaska Air Group is pouring money into fancier seats and lounges for Hawaiian Airlines, which is good news for business travelers but does nothing to lower fares for locals flying between islands.

• Hawaiian's A330s get four cabin classes by 2028, topped by lie-flat suites with doors.
• To make room, 24 regular seats per plane get cut and 12 more move up to pricier tiers.
• A big new lounge is coming to Honolulu's Terminal 1, plus faster check-in and security for top-tier flyers.
• The old 717 planes are being retired for cheaper-to-run 737s, which management says will help hold fares down.
• Interisland ticket prices are not dropping, but more money from the front of the plane is supposed to ease pressure on the back.

Outlook: Changes start rolling out this week with international check-in moving to Terminal 2, while the cabin overhaul stretches out to 2028.
