I will also say that even if the online booking tool processes your itinerary and accepts payment, resulting in a PNR.. there is NO guarantee that your trip will actually ticket. I just went through that nightmare recently -- online tool "accepted" itinerary, but reservation never ticketed. Despite contacting many QF phone and Facebook agents, I kept getting a range of nonsense excuses ("You can only have 5 stopovers") or "I'll put it in the booking queue" but nothing happened. If the system doesn't automatically ticket your reservation, good luck finding a knowledgeable agent that can diagnose the problem AND fix the problem. If there's any consolation in the online tool route, it's that there is never usually a wait to speak with a QF phone agent. The FB support, although slightly more knowledgeable, was not consistently responsive in a timely manner.
