What's strange to me is that if you do a search like...

From: YYC
To: QVR;HKG (or any airport within 200 miles)

Sep 4 - 13

It still finds a YYC -> HKG fare, but it's just not finding the *lowest* one. It finds a $940 fare as the cheapest.

It seems to go against the theory that it's just searching for the first 500 results between YYC and QVR first, and then HKG next.
