The OP stated that this is a Delta issue, the link provided shows that it is happening to other airlines.

I agree revenue is revenue but the honeymooners are AA Plats equivalent to DL Gold so they would be higher than the OP on the totum pole (OP states they are FO)

The honeymooners spent thousands of dollars on the tickets to Hawaii, pretty sure they would beat the OP on fare paid

I am just suggesting to the OP that they are not alone and it is not only a DL problem. Obviously you didn't look at that thread because the facts would lead to the honeymooners getting helped ahead of the OP based on every criteria you just listed.

PLUS who do you think a GA is going to try and help more, a honeymoon couple or a mileage runner? I'm not saying its right but I think most people would be stretching the rules to try and get that honeymoon off to a good start over someone who was just flying around the country to ultimately return to where they currently were the same day. Like it or not, that is also taken into consideration. But as you can see from the information above, the honeymooners would/should have been handled first according to your criteria
