In practice, however, only a few trains originate or terminate at Temple University; most are through routed with lines to the north after leaving the Center City Commuter Connection.

The line between Center City and the airport runs seven days a week from 5:00 am to midnight with trains every 30 minutes daily.

The line stops at four stations which are directly connected to each airport terminal by escalators and elevators which rise one level to the walkways between the arrival and departure areas.

All airport stations feature high-level platforms to make it easier to board and alight from the train with luggage.

The line passed into Conrail in 1976 and SEPTA in 1983, with passenger service to the Philadelphia International Airport beginning on April 28, 1985.

All these stations appeared on 1984 SEPTA informational maps, the first ones to show the Center City Commuter Connection and the Airport Line.
