Except that's not a quote from anyone at HA -- it's from the CEO of Air China. And it's more logical to view that statement in the context of offering CA passengers the ability to visit both Hawaii and the U.S. mainland on a single itinerary, rather than connecting passengers from China to the U.S. mainland at HNL. After all, CA serves LAX/SFO/JFK non-stop on its own equipment and has access to the UA network via Star Alliance.
No rest, I'm afraid. Not as long as there are people who disagree with you and have their own booking preferences. I am firmly in the anti-narrowbody crowd when it comes to flight times greater than 5-6 hours. There are many folks who choose to fly on a widebody every time, hands down when it is an option. And I would even give serious consideration to a widebody connection versus a narrowbody nonstop. It is the both the absolute spaciousness and also the perception of spaciousness (two very different things) that make people prefer widebodies.
And yet that's still just anecdata. You don't think that marketing teams at the airlines don't look at customer preferences in cooperation with planning teams? Widebodies don't produce enough of a revenue premium, especially when balanced against capacity risk, for most markets without large premium demand. Markets with large premium demand get widebodies because those aircraft have room for large J cabins. And a product like Mint on B6 is touted as a huge success even though B6 doesn't fly a single widebody aircraft.
You may have your preferences, but the market has spoken. AS's success to Hawaii has basically been built on offering non-stop point-to-point services on narrowbody aircraft.
LAS and PHX are both A330 routes during normal, non-COVID times.
LAS is basically the 9th island so the demand for a widebody is always there outside of weird pandemic times. Heck, HA could probably even fill an A380 to LAS (but no, they should not be purchasing used A380s).
I'm still scratching my head as to why HA ditched the A330neo type entirely instead of buying into the A339. It would have kept Hawaiian's simple pool of "interisland" and "overseas" cabin/flight crew versus the mess the 787-9 will bring.
Because being able to use the optimal aircraft for the market in this case is more efficient than some relatively small efficiencies to be gained with cross-qualification between the A332 and A339.
