The problem is, Corrigan is a lot closer to the 50% mark needed to exert effective control than Branson is. Given what he has said recently in the media about wanting to get out of a price war, and given his preference for 'cosy duopolies' in the stevedoring and rail industries here, I think it would be quite a shame if Corrigan did manage to push over the 50% mark.
The key to Virgin's success has been how it has challenged the market norms, whereas Corrigan seems to talk about sitting comfortably in the market. The problem is, someone else will always have a go at challenging, and if Virgin Blue sit on their laurels (as I think Corrigan would like), then they will quickly find themselves in an equally concerning position as the price war - their market being eroded from both sides, and no real means of mounting a counter attack.
I hope he doesn't get past the 50% mark, or that if he does, I'm wrong. We don't need to go back to a cosy duopoly, or heaven forbid, a monopoly...
