From 1946, the DC-4s were used to commence international services from Houston and New Orleans to Havana, Cuba; Santo Domingo (which was known as Ciudad Trujillo from 1930 to 1961), Dominican Republic; Kingston, Jamaica and Caracas, Venezuela. The February 1, 1947 Chicago & Southern system timetable route map includes all of these destinations as well as Aruba, Netherlands Antilles; Camaguey, Cuba; Curacao, Netherlands Antilles; Port au Prince, Haiti and San Juan, Puerto Rico; however, it appears that although passenger traffic rights may have been granted or applied for, these additional destinations were not being served at this time.
