I flew out of LaGuardia around 1963-64 and at the time American Airlines
was using one of those Teleregister systems for reservations purposes,
before Sabre came on line.  A class of seat on a flight on a certain day
was a part number.  Each time they sold a ticket it decreased the
inventory of that part number.  I remember there were some coded metal
plates as part of the agent set that translated flight numbers into
part numbers.
