No apology necessary - I sorta figured you meant either fly the plane on a route that would be both profitable and a better fit for it's performance or retire it.
I stand by what I said - they thought/think that the route will be profitable and accepted that it would require a fuel stop some percentage of the time (more in winter, less in summer because of normal wind patterns that change with the seasons). Given the financial shape US is in, if there were a different route that they thought would be more profitable I can't come up with a reason the 767 would not be on that route instead of CLT-HNL. Like I said, it's not like US is awash in cash and need to dispose of some of it.
Some talk about HI being a low yield market, and it is compared to some. But at 16.5 cents a mile for the cheapest non-refundable coach ticket over a month from now, it's profitable with a 70% or less average load factor. Throw in a few FC or refundable coach tickets sold, and the break even load factor drops. Most long haul flights are like that - the yield is less than short haul routes where there's no low cost carrier to set the low fare, but the cost is less per mile too.
You've also got to remember that US' 767's have plenty of range to make HNL non-stop unless the winds are especially strong for a large portion of the flight. The difference between a 50 and 100 kt headwind for the entire cruise portion is effectivley a 350 nm reducton in range. A 150 kt headwind is another 350 nm reduction in range. Even in the winter you can fly around for weeks and not see 100 kt winds at altitude over any big area. Unfortunately, the flight started with over 100 kt winds aloft pretty much all the way to HI.
And for California Girl, yes - Parker/Kirby don't personally do the route planning and probably don't have a clue how to if they tried. But they're at the top of the food chain so the buck stops with them.
