We have a BA family account.
Three questions:
1) On the BA webpage it states: "Card expiry date: 31 Jan 2018".
None of us has a BA credit card account open, so what card are they referring to?

2) I cannot locate the expiration date for the Avios on the BA page. Is it not listed somewhere?
(I used some Avios one year ago, so I assume the expiration date was extended by that.)

3) If one member of our family account (e.g., me) uses some Avios, would that extend the expiration date of the Avios for each member of the family account, or for just me?

Thanks in advance for your help.
