There was long ago another factor in the Hawaiian-Aloha competition that people don't like to talk about, but was relevant to the 50s and 60s. Aloha was founded by a Chinese group, and many local Asians preferred Aloha because they received condescending service from Hawaiian which was haole-owned. It's not just a Ford and GM thing: for neighbor-island Chinese like my parents and grandparents, it was a way of escaping petty racism. This was really glossed over in the news about Aloha's demise, and of course it vanished by the 70s. But it was not all sweetness and light in HI. I myself preferred Hawaiian once they got the new 717s since AQ (TS) ran those scary 732s.
