As with most airlines Hawaii does does not make much money. However airlines do fly it so their frequent fliers will have place to "spend" their miles. Additionally, it is intersting to note that since the DC10's and L1011's have been parked as well as the older 747's and being replaced by 757's 767's etc many "excess" seats have been eliminated from the market. This has slightly pushed the yields up on the flights (supply and demand). Fianlly with the fuel savings, the trips do occasionally post a slight profit.,
