Hawaiian Airlines is tightening check-in deadlines and reshaping its rewards program, which is annoying for last-minute island hoppers but better for frequent flyers.

• Starting Saturday, neighbor island travelers have to check in and drop bags 50 minutes before takeoff, up from 30.
• Hawaiian says the longer window helps planes leave on time, since late bags slow down ramp crews.
• Travelers worry that traffic and accidents will make the tighter deadline hard to hit.
• International flights out of Honolulu move to Terminal 2, Lobby 4, also starting Saturday.
• Members can now pick how they earn points — by distance flown, ticket price, or segments — and switch once a year.

Outlook: Cheap long-haul tickets favor earning by distance while pricey ones favor fare-based earning, and the new flexibility is being seen as one of the clearer wins from the Alaska-Hawaiian merger.
