Maybe we need to clarify this scenario.  I was assuming that the air carrier
was trying to fly more pax than the aircraft had been *certificated* to, which
is admittedly a slightly different from (1) what has been demonstrated with
the aircraft, and (2) the maximum number of pax which have actually been flown
in service by an air carrier.

Perhaps someone could explain the exact methodology used in each of the three
cases:  (1) more pax than had been certificated, (2) more pax than have been
demonstrated, and (3) more pax than had been flown in service, but fewer than

Assuming scenario (1) I have a further question:  which FAA region would be
responsible for approving the configuration - the region of the aircraft type
certificating agency (e.g. Northwest Mountain Region for Boeing), or the
region of the air carrier (e.g. Southwest Region for AA) ?
