in short.... bought enough stock in Aloha to have a seat at the table for strategic company planning sessions.... then used the inside information to run Go! in such a fassion that Aloha would eventually fail and go bankrupt.

In really short terms.... Mesa learned what Aloha's real costs were, then Mesa subsidized Go!, selling tickets at below actual cost until Aloha went thumbs up.

A few other issues as well, but the misuse of inside information is what got them fined... but by then it was too late to save Aloha.

So, it was both morally and legally wrong, but it would result in JO getting his way.... and at the time was an affordable means to an end; so, he did it.
