At the end of April, SEPTA will offer a new, unlimited, daypass, called the “Independence Pass”. This will be good for unlimited trips on bus, trolley, subway-elevated, Regional Rail (after the morning rush hours), and PHLASH bus service. The pass will cost $10 for individuals, and $25 for families.
