This fare is valid on select dates through the end of scheduling. Flights stop in JFK or Atlanta.
You must originate in Philadelphia or else the rest of your ticket will be cancelled. However if your return flight is via JFK you can get off the flight in JFK and not take the final leg to Philadelphia.
Even if your bag is checked to Philadelphia all luggage must be collected in JFK and brought through customs. At that point you can recheck your bags or just leave the airport.
