It does seem unlikely, although UAL would reserve the right to "adjust" the qualifications in a particular instance.
It would be interesting however to learn under what circumstances Global Services was initiated and how many <$200k per annum wage earners typically qualify for such cream of the elite treatment. We all know people who book more mileage than she does and make more money than she does who are not in the program. Perhaps the program was a defensive maneuver by UAL faced with snotty nosed public figures.
IMO, it is unlikely the bumped passenger actually canceled her flight and she seems willing to go to the mat on the issue. So the question is whether UAL just reached in and bumped a first-class passenger to avoid dealing with SJL. The smart bet is UAL made that specific decision long ago.
If that becomes provable, then SJL's behavior casts a dark shadow on the entire Congress and would justifiably be the subject of a censure.
All the more reason to avoid United Airlines. Do any other airlines also pull that stunt of telling a passenger that they just cancelled their flight?
To be sure they gave her a voucher for $500--but that can only be used toward another flight on UAL, I assume. And she is lucky--she didn't have any of her teeth knocked out.
