I'm talking about the airport lots, not the private off-airport ones. I have a one-day trip to make next Thursday, flying out on US (Terminal F) at 7:40 AM. Anyone have a good idea of what my chances of getting a parking spot in the E or C lot would be? I've been locked out of the PHL lots before, and don't want to chance that happening again. If I hear enough warnings I will just go ahead and make a reservation at Priority Parking, although for a one-day trip this is kind of a pain.
