So I recently flew some inter-island flights on Hawaiian Airlines. They didn't know what to do with my WP# so I mailed in my Boarding Passes to NW later. The flights now show up in my WP account, but have been credited zero miles because of something called "Code N" ... seems pretty lame to me, did something change with NW and Hawaiian recently that's not shown on the website yet? (The fare class was L/L)
