Some of the comments here about JQ and Mainline QF miss the boat.
The official, well-publicised, plan has always been to move marginal routes to JQ first, and then expand JQ to pull back market share by exploiting emerging Low Cost markets. Mainline growth was always forecast to be lower (but growth nevertheless ) .
Nett result - group growth and increasing market share. Seems a sensible plan to me.
It's only 787 delivery delays that have slowed it down.
