How early do you need to catch the train from Philadelphia to make an international flight out of Newark?
Planning the train plus budget flight trick for a Paris trip. NJ Transit from 30th Street to Newark Airport, then an international flight out of EWR. What I can't figure out is the timing. How much buffer do you really need? Does checking a bag change things, and does customs slow you down on the way out? Would hate to save $400 on the flight and then miss it standing on a platform.
