Yes, Aloha flew cargo inter-island, but they were with non-pax configured 737 aircraft just as ugly as ours on the inside ---- I saw them on display at an airshow at Kalaeola Airport (the old Barbers Point Field) around 2004 before they went completely belly up.

I think the cargo portion of Aloha was eventually sold off in the liquidation, and is the only portion of the previous operation still flying.
