Actually, I think that for AA to make an open reservation they must make a dated reservation, thereby confirming to the computer that the flight exists, and then when its ticketed its done so as OPEN. If they are asking for the flights in order to avoid ticketing as OPEN then yes its a training issue. But I expect its the former in this case.
