Hi CX readers,

Seeing a very strange bug on the CX website.
Trying to book a multi city booking.

When entering my QR number during the booking (personal details) the website errors out and instructs to contact Customer Care.
When entering a BA number or leaving it blank it seems to work.

As I had some issues previously with CX miles crediting I want to make sure the number is there during the booking.
I can't use BA beause P fare doesn't earn TP or avios on BA.

Did anyone encounter this before? Or should I just leave it blank and try adding it during check-in or at the airport?
