So looks like VA will probably complete the 737 Inflight Internet rollout before QF.
Yes, VA expects 737s to be completed by mid-year.. There was some confusion about the 73Gs which is still unclear. It is also likely 2 of the older 738s will be moved to TT (one heading to paint this weekend) so they won't be done. I believe QF are probably a few months behind that schedule though it has fitted a few of the domestic-centric A332s (EBA-EBE range) with SkyMuster WiFi whereas VA won't start its A330s until July.
As far as long-haul is concerned, VA has finished its 77Ws. I don't believe QF has even announced what product it will use for the international fleet (380/333/332/789) but it has to be different form the domestic fleet which only work with the NBN SkyMuster satellites.
