At 1:22 into the video the voice over states "also collect double avios every time you fly with us or any of our oneworld partners".

Is this benefit changing or is the video telling porkies?

The collecting avios pages still only show a few of the OW partners as earning the tier point bonus.

The video is misleading on other ways in that it shows the CR dining area when talking about First lounge access for Gold card holders.
