As you mainly do TATL, then AA or BA would be the logical choice. AA has a better earn/burn rate, but BA may be better if you fly BA TATL and want to upgrade.
For clarity, I do many more miles with my TPACs than TATL (approx 60% of my miles come from trips to HKG/MNL.) Does the same guidance hold true? Ie choose based upon the carrier I'll be using when travelling leisure, assuming that J and benefits comes with work travel?
