Is walking from the economy parking lot at PHL to terminal F feasible? I'll soon have my first departure out of F. From a satellite image, it looks like the closest-to-the-airport corner of the economy lot is about 1000 feet from terminal F (ie shorter than the walk from security to the end of the terminal). It also looks like there's a sidewalk, crosswalks, and a way out of the lot, although I can't tell if there's a fence.

Has anyone done this, particularly since the new airside F connector opened?
