Then you can't really hold that against HH... If they had all of those locations when you were earning points and then the properties start dropping out of the system for whatever reason, it'd be a different story.

Only sliver of hope: in that specific merger, it would almost certainly be AAdvantage that survives. The branding, the Oneworld alliance, the IT systems...everything. So maybe, just maybe, the FFP side of things would stay more like AA and less like US.
