Due to opposition from the United States, the German airline was unable to operate these aircraft on the intended transatlantic route; instead, in 1939 they were used to carry air mail between Bathurst and Natal in South Africa.
Díky protestům USA, Lufthansa nemohla provozovat tato letadla na zamýšlené trase mezi Evropou a USA, místo toho byly používány v roce 1939 k přepravě pošty mezi Bathurstem a Natalem v Jižní Africe.
