This airport is very clean and easy to navigate in. I usually fly in via Hawaiian Airlines and catch a monorail to the baggage claim.
Bathrooms are clean and there are plenty of them. There are a lot of choices when it comes to food, beverages, bookstores and souvenirs. There are also slot machines here, someone just won the jackpot on the wheel of fortune machine by the Hawaiian airlines gate this week.
There was a kiosk where you could quick charge your electronics (not free) but there are also scattered outlets you can use also (free!)
Right outside the baggage claim there are shuttles that take you to the car rental center which is super convenient.
