My son is travelling on orders and will be flying United but told me he is not allowed to input his FF number as it is a government paid flight. Is that true?
That is absolutely false. You son will be provided a United confirmation number (or he could use his travel authorization code) once the flight is confirmed. He can plug that number into United find reservation and from there he can associate his MileagePlus information with that reservation.
