I mean that I wish it wasn't only flying activities that extend the validity of our miles. If other select activities permitted extension of miles validity, that would be a lot fairer. The programs of British Airways and Iberia are like this. In our case it could be a select car rental or hotel partner, such as Accor. But if you are an infrequent Accor guest, like me, it can be quite tricky keeping the points alive. You really need to do a stay to extend them, no other activity appears to do the trick.
