AA is gonna do whatever they think is best, but personally I would absolutely LOVE to see MIA-CPT. The current routing via DOH is cumbersome and LHR on BA is often unpalatable due to exorbitant fees. Fingers crossed.

Also agree with others that the whole point of PR joining oneworld is that AA does NOT need to fly there.

HKG and MEL are well served by oneworld partners as well. CPT would open up a whole new corner of the globe that's really hard to reach currently.
