A segment is a flight between two airports, with the caveat that a direct flight with a stop (ie, both flights have the same flight number) is one segment. This is standard industry-wide and really has nothing to do with AA.
Must not be truly industry-wide, as WN through flights collect segments individually. For example, fly BWI-MDW-LAS on the same WN flight number, WN awards 2 segments towards qualifying.
