BTW, I am in Kauai this week. Landing at Lihue (PHLI) on Friday there was an Alaska Airlines 737 (800?, NG?) parked at the terminal. I presume it came from PANC. Or,perhaps Seattle? Anywhere else seems a bit of a stretch.
I think AS does PLHI-KSEA and PHLI-KLAX right now. -800SFP. All the islands are a stretch in a 737, really.
