I'm not convinced, because EF uses a US point of sale for all award searches, and EF can show EY F/J availability, but US-based AA agents often can't see it. Further, US-based agents seem to have no problem seeing and booking EY F/J for flights that are not to/from the US, and also no problem booking EY F/J for flights to/from the US within 30 days. I would think that if it was a simple point-of-sale issue, that US-based AA agents could always see and book what EF shows (the other oddities could be explained as EY PoS availability, but not the mismatch between EF and US-based AA agents). I suppose there might be a point-of-sale issue that only manifests via AA's direct-access interface, not through a GDS, but that seems unlikely.
