Kulula is indeed a complete joke in it's current state in terms of scheduling - that said, you have to consider why, and how it relates to 1Time. Kulula are running with NO margin for error (or even negative margins) in order to maximise usage, and thus profitability, to finance the new fleet of -800's. The three, soon to be four, on lease will be supplemented by brand new aircraft (Really brand new from Boeing, as opposed to 'Kulula' new
) at some stage in the next few years. (2012?) I'm told that they've had to jump through several financial hoops, and demonstrate suitably awesome levels of profitability to secure the loans. Thats even after having made a profit for the last 60 years or whatever they're always going on about. And it's still no excuse for being late all the time of course.
Simply put, it may be beyond 1Time to get that kind of backing, or it may raise their operating cost beyond what they claim to be. Who knows.
