That is incorrect, AA has no arrangement of any sort with EK -- they have it with Gulf Air, a competitor of EK (presumably what you remembered). Similarly AirBerlin are partially owned by Etihad, another EK competitor. Rather ironically it is now possible to become OW Emerald without ever having flown a single mile on a Oneworld airline
But not by flying EK, at least prior to the QF deal which is still up in the air.
