Things are a bit slower...
QF is choosing to grow a little slow - 0.5% rather than 2%
Reality is the larger part of QF hasn't done much new aircraft growth for a while
Last 737 - Nov 2014
Last 330 - Dec 2012 (granted planes back from JQ up to Sep 2015)
Last 380 - Dec 2011
Only some second hand 717s
Mainline fleet age must be creeping up again with no replacements - and the only thing on the horizon is 8 787s in 15+ months
Increasing the seatcout on 67 737s by 6 seats will help
