Thank you for reaching out on Italiapass! The Naples - Pompei route is currently unavailable for the month of September. The schedule should be released around the beginning to the middle of August. Since the Naples - Pompei route takes place on a regional train, this has an impact on the schedule's release time. Regional train schedules sometimes are only released 30 days prior to the departure date.
