I think it is great that CO is adding Hawaii flights while also improving fleet utilization. And while I know the narrow v widebody aircraft is huge amongst us aerogeeks, the simple fact remains than John and Jane Q. Public focus on price and schedule, not the specific aircraft. And more so to Hawaii, which is primarily a leisure destination.
IMHO, more power to CO and I hope they expand to LIH and KOA. Sure, F is not as nice as BF but I value a chance for an upgrade and/or the direct flight when I am paying for tickets. Plus, given that I need to connect anyhow, I like breaking it up midway (as I am in a couple weeks).
