I have a question about the reverse: checking baggage through from VX to VA. A few months ago I tried to book flights to the US with BNE-LAX going over, and JFK-LAX-BNE coming back. Since the website wasn't able to book a multi city itinerary like that, I had to call the call centre. I asked if I booked the VX JFK-LAX flight separately, would I be able to check luggage straight through from JFK to BNE. The operator said that even if it was on the same ticket I would have to collect and re-check my luggage in LAX anyway. I'm not sure if there was a miscommunication and the operator thought I was talking about arriving in LAX from Australia and then connecting to a domestic US flight, or if it really is (was?) a thing that VX and VA don't join up all that well.
So is that actually the case? Is it something that will be fixed up with the Sabre transition? It's kind of a moot point for me now, since I ended up booking the JFK-LAX flight as a separate ticket with a long enough layover that it won't be a huge hassle to check in again at LAX. But anyway, I was just curious. This will be the first time I've flown VA to the US, and it seemed a little odd.
