I'll find out in a few days when I pass through AA@LAX, but I suspect it can't really be an issue, and I have the WP1 white card, which is a big difference to the older design/scheme.
- card has QF branding, expiry date and OW status logo
- BP will (or SHOULD) also confirm emerald or saphire status
so I doubt it would be a real issue, but hey they can call QF to confirm if it's really a concern.
