Not exactly certain, but it probably pre-dates the EAL deal by a couple years.
In the mid to late 1980's, there was a proposal for AA to bid on taking over the Intra-German Services then operated by Pan Am.
Prior to reunification, LH was prohibited from flying between Berlin and West Germany. So PA was the only carrier flying between TXL and FRA/HAM/MUC/NUE/STR.
Had we gotten the contract, AA was going to have a small number of 727s based in TXL and IIRC, all crew members would have been required to be fluent in both German and English (i.e. the Berlitz four-week crash course was not an option).
Probably a good thing in hindsight that it didn't happen -- once the GDR collapsed, the restrictions on LH being able to fly between Berlin and the rest of Germany were obviously lifted.
