Pretty stunning how high interisland airfares have become -- many are almost $200 roundtrip, and there don't seem to be a lot of low fare alternatives. I cashed in 5000 miles on UA for an Aloha flight, which seemed a lot better than the alternatives. How are the locals getting around? Given the paltry distances, you would think an efficient airline could price 14-day advance tickets at $39 or $49 and make money. I hope that highspeed ferry provides some competition.
