How can I buy Hawaiian Airlines tickets with a corporate account or otherwise get free checked bags?

I've gotten free bags on http://en.wikipedia.org/wiki/Hawaiian_Airlines when my ticket was issued by another airline.  I flew from http://en.wikipedia.org/wiki/Hilo_International_Airport through http://en.wikipedia.org/wiki/Honolulu_International_Airport to http://en.wikipedia.org/wiki/Nadi_International_Airport, Fiji, on a ticket issued by http://en.wikipedia.org/wiki/Fiji_Airways, so their rules applied, and of course on an international itinerary I was able to check a bag or two for free. I'm not sure, but the same sort of thing might apply on: Inter-island flights that are part of Hawaiian itineraries to international destinations (in Korea, Japan, Taiwan, Australia, New Zealand, or Tahiti) Itineraries that include inter-island flights on Hawaiian but are issued by other airlines and qualify for free bags through those airlines due to elite status or whatever It's worth checking on a case-by-case basis.
