red/wave/orange, let me put this into a strictly business sense - not related to any 'wish' we have to stay separate. The question is - why would anyone buy Hawaiian? The answer is that it would either a) provide an increase in revenue to make the business grow, or b) provide feed to the current system of the purchasing airline, or c) reduce competition, to allow higher fares for the purchaser.
For a), the problem is that unless the purchaser left HA completely alone as a separate airline, there would be no increase in profits. The ONLY reason HA is profitable is its current business model. HA charges more per seat on average than the competition, and the only reason they are able to do that is the very specific service model they provide. People are willing to pay more to get better service - our current business model proves that. Do you see SWA suddenly agreeing to charge more and provide free meals on its flights? Do you see SWA staffing flights with more than the minimum required number of FAs? Do you see SWA providing passengers with all the amenities that HA does on its longhaul flights? No. If SWA (or any other current U.S. airline) were to buy HA they would change their service & business model to fit into their own, and suddenly all that extra fares HA charges would have to go away, and so would its profits. Like Dan has said so many times before, the business model of HA wouldn't fit into any other airline. Take that business model away, and suddenly HA becomes a money pit that no other airline would touch.
For reason b), that same business model of bringing people to Hawaii wouldn't fit in connecting passengers to feed the purchasing airline, because the flights arrive on the west coast too late to do anything with them, other than put them up in a hotel. Change the departure times, you say? Fine. Then you've killed the business model, because (as we've discovered) most passengers don't want to get up at 5am in Hawaii to catch an 8am departure. We've tried, and with a couple of exceptions, it didn't work.
And for reason c), none of the potential suitors for HA would consider our flights to be competition. SWA certainly isn't flying any of our routes, and if AS or UA or AA or DL wanted to buy us, it would be cheaper to simply put more of their own planes on the routes that go through the expense of trying to buy us. It simply wouldn't be worth the cost of buying us when it would be cheaper to simply add more of their own flights.
So from a business sense, a merger - especially with SWA - just doesn't make sense. If you have other business related reasons why it would, I'd love to hear them.
