That's my hunch too (since you can basically forget anything like 5 digit numbers of alphanumeric due to old DBs that can't be migrated easily).
Probably the issue is that lots of assumptions around AA exclusively being American Airlines is baked in somewhere. That said, it seems easier than any of the alternatives (and recycling seems excessively risky and confusing).
