Alex: in principle on a Global Explorer or a OneWorld Explorer you can use code shares provided that the flight is operated by an eligible carrier. Whether there is any availability in L on the codeshares is another matter. But it doesn't seem to be a big problem to get 10,000 miles on AA metal on a RTW - one transatlantic and 3 or 4 segments within N America gets you there.

RTW4: oops, sorry - my mistake - it is Gulf Air not Emirates. Rules here: http://www.hardlink.com/~markdu/OWFiles/
