Neo Single-aisle planes for West Coast routes: well, they certainly wasted a lot of advertising over the past few years telling us Californians how we deserved a jumbo jet (unlike Alaska's 737s and the various 320s and 757's) and we ought to fly Hawaiian.
This pitch has gone on for some time; now, HA will be flying pint-sized metal to the islands, too. If that was their plan, hope they fire whomever thought up the whole big plane campaign. What a waste!
A330 service to the west coast isn't going away, they will still have more widebodies than the competition.
