BOS is likely to be crowded, HNL is a Qantas Club (admitting AA pax) until the departure of the QF flight to Sydney (after which a mad scurry occurs where the goodies are stashed away and it becomes a skinflinty Admirals Club.) The HNL AC is also a bit distant from the AA gates - you will have some walking to do.

LAX has showers if you have time between flights, and is very close to the gates. DFW has several clubs - if you have time and want a shower on your return from the HNL redeye, shoot for Terminal A and the rain showers there, usually easy to access (A used to be the international terminal and is often much less crowded; now D is international, with the newest Club at DFW - showers too, but can have queues.)

Most Clubs have a selection of "adult" and non-adult beverages and a menu of "Amora" food items available for sale, and not much for free other than pretzels or pretzel mix, possibly apples, occasionally cookies / biscuits, mini-muffins or the like, tea, coffee, water, maybe juice.
