I think there must a fair degree of misunderstanding on both sides. My apologies.

My original post was regarding the ability to upgrade Lan sectors on a One World Explorer ticket (L). This thread does have a section re the ability to upgrade individual sectors on CX, BA & AA. I was just confirming that it is also possible to upgrade individual sectors with Lan.

As a regular OWE buyer the ability to upgrade individual sectors is extremely important to me. As far I can see this is the correct thread to comment on this issue.
