Hmm, there is a lot being said about HNL for J*International, I would be surprised if they would go there.
Their target market obviously will be for those lookin for a cheap flight, as well as a chap holiday.
Considering the demographics of those pax who already fly there (newly-weds and nearly-deads) I doubt those people would want the J* product. The other factors I see against HNL would be the cost of accommodation for tourists isn HNL is very high (compared to Asian ports), the cost of exepenses ie food, entertainment, activities there is also comparitively high, ruling out the backpacker market.
The Asian destinations such as Phuket, Vietnam, Cambodia etc would be more in line with the target market. It would also allow cheap labour hire (ie cabin crew) in each port, again this would not be the case in HNL, or other US cities. There is a strong rumour that J* will have their cabin crew based mostly overseas
Just some thoughts !
