oneworld - Qantas vs. BA Engine Award Availability?

I always thought that QF had the glitchy award space and that BA was the accurate one. However, on August 1 2013, BA.com has 2 CX F seats for both CX831 and CX841 while QF.com doesn't; it only has space for the CX841.

Can anyone explain this?
Which site is right?

Also, QF doesn't show any J/F seats on Cx888 YVR-JFK any of the 330 days.

The JL website is the most accurate concerning award availability on CX flights.

QF's website has a patchy record of showing CX award flights. Until recently, you often couldn't find anything at all.

The JL website is the most accurate concerning award availability on CX flights.

I keep getting a system is busy message... for JL
