Sean, what will your answer be in a year or so, when all of mainline could potentially be switched to Song?

All of mainline cannot be switched to Song for the simple reason that Song is based upon the concept of economies of scale via standardization and efficiency. To go into that with a mix of 757s, 762, 763s, 764s, 738s, etc.. will never work.
Song is a niche carrier that may see its niche expand significantly. But it will never replace mainline entirely the way it is currently structured to run.
