Thanks for the replies.
Here's some more info on my situation....

It will actually be one trip per month....with a 20 day (or so) stay each time.

It looks like AA is what I prefer, cuz they have better partners with Cathay, and Qantas.

I book my own flights, and my own hotels....and my company pays for both.

I'm allowed to fly coach, or premier, but not business class. The fare hikes from $2.5K up to $12K+....so that's a no-no.
