The reason I ask is that I'm using the online tool and I can slot vancouver in there, but I can never find a flight.

My ideal would be something like
Brisbane - Los Angelos - San Francisco - Vancouver - New York - Rio

I'd be happy with about any combo that would let me slot vancouver in though.

I'm looking to fly sometime in January. I thought maybe it was the timing, but even when i push back the dates to next july I still can't find a single flight to vancouver. I had a go from Los Angelos as well, but no dice.
