Makes me wonder if the Corleone family availed themselves of Vavolizza's services to arrange Michael's passage to Sicily after the Sollozzo/McCluskey hit?
Could be Lou was over there - he may have felt a need to get out of town for a while.
Way off topic: Does anyone know how travel agencies worked then? They didn't have any links to computer systems, so would they just call a railroad/cruise line to make the reservation, and then write out the ticket on a standard form?
