Dear Lady luck.
Good luck! As a veteran of Qantas I can tell you that it will be the slog and flog approach that Geoff Dixon has instilled in his managers. For those of us that remember the days when safety came first, the current approach of profit first is an accident waiting to happen. If you accept that then you will probably enjoy the time you spend with Jetstar. If you don't expect too much then you won't be disappointed.
Virgin will always retain an advantage over Jetstar while their management approach is the way it is. It is people that make an airline but sadly Geoff has forgotten this.
