I'm new here, so I apologize if I missed this somewhere earlier....
I am a leisure traveler, so I don't make too many BA flights. My husband and I both have some older Avios he got a note his were about to expire. We have the BA Chase Visa so I am earning Avios currently so I guess mine won't expire the same way? If we merge to a HHA will this 'save' his miles from expiring?
