Hawaiian Airlines started HawaiianMiles, their frequent-flyer program, in 1983. Miles accumulated in the program allow members to redeem tickets, upgrade service class or obtain free or discounted car rentals, hotel stays, merchandise, or other products and services through partners. The most active members, based on the amount and price of travel booked, are designated Pualani Gold (fly 30 Segments or fly 20,000 Flight Miles) and Pualani Platinum (fly 60 Segments or fly 40,000 Flight Miles), with privileges such as separate check-in, Premier Club Lounge access in Honolulu, Hilo, Kona, Kahului, and Līhuʻe, priority upgrade and standby processing, or complimentary upgrades. Travel award redemption from the HawaiianMiles program account for 5% of total revenue passengers.
Analysis of the 1992–1996 period shows that every player in the air transport chain is far more profitable than the airlines, who collect and pass through fees and revenues to them from ticket sales. While airlines as a whole earned 6% return on capital employed (2–3.5% less than the cost of capital), airports earned 10%, catering companies 10–13%, handling companies 11–14%, aircraft lessors 15%, aircraft manufacturers 16%, and global distribution companies more than 30%.

The retention of the fresh water may also help to maintain underground water reserves and will resist salt water incursion. If the surface flow of the runoff is diverted and concentrated by drains that create constant flows over the beach above the sea or river level, the beach will be eroded and ultimately form an inlet unless longshore flows deposit sediments to repair the breach.
In October 2015, Hawaiian Airlines announced that they will be upgrading their business class seats from the standard cradle seats to a 180-degree lie-flat seats on their A330 fleet in a 2-2-2 configuration. The new seats will be installed starting the second quarter of 2016. In addition to the new business class seats upgrade, the airline will add 28 additional Extra Comfort seating.
