I believe that AA dropped that plan when Mr. Raja left the company.

Ok good to know.

Even if EF is accurate in this regard, why would you want to book this fare with an airline that has basically no experience with the complicated rules that govern the fare?

Nobody is suggesting that the fare be booked with AS agents. Full stop. The only scenario I'm suggesting is using a TA ( again, not AS agents) to price using the AS fare. Seeing as how the AA fares are required to have AA coded overwater segment, maybe the AS fares don't have such rules? I don't know, this is all open question.

I believe that it's an unpublished requirement. Note that AA codeshares on other carriers' metal meet the requirement.
Yes, I realize that. The point of considering AS over AA fares is to avoid AA coded flights that don't credit well with BA or AA programs. No other reason driving this exercise.
