HI guys,
One of my household member avios points might get expire as per their 36months no activity. the following is the last activity when i see their statement

I am bit confused by seeing the last activty is April 02nd 2025 but the actual redemption activity in November 29th, 2025. so not sure which one is the last activity will be treated not to get expired.

Also have another question, incase if i have to unexpire this house hold account, if transfer between account counts as activity or i should only redeem or earn?
If i have to earn/burn to unexpire the date, is it possible to earn/burn in any of the accounts or only in this specific account which does not have any activity for the past 36 months.
Appreciate your help
