In hindsight, I probably shouldn't have booked that connection. I'm not familiar with Philly, and the terminal map made it seem that Terminal F was connected to the others with a quick walk. I also assumed that train track looking thing on the map was the airside-landside divider, which would put the Terminal E-F connector as airside. And I guess I was naive about Kayak and Priceline not giving nearly impossible itineraries.

Lesson learned. Also, I know now that if I want to dress up for my job interview in Scranton, I shall pack my suit in my carryon suitcase.

Also, I'm a glutton for punishment because on the return trip, I have a 47 minute layover in DTW. Though I've made tighter connections there that involved jogging the full mile from the far end of C to the far end of A...

Thanks everyone for the advice
