Word is that quite a few of the Dash 8 pilots are not very happy with the way things are managed. Things like tours, promotions and the introduction of the Q400, not to mention crewing are the major issues. Although there are a couple of guys bouncing of walls because the Massey Ferguson Tractor owner/driver has been slightly displaced into another role.
Given the way the airlines in OZ are recruiting at the moment there could be a mass walkout in the near future. As mentioned above, the problems aren't so much with the flying, it's really related to management issues which directly relate to peoples lifestyles. PNG itself is hard enough to live and work in, let alone having management and crewing treat pilots like machines.
