I have a 52 minute connection at PHL Monday morning between 1826 and 3772. Debating checking luggage as it's carry on size but I'd honestly prefer not to deal with it as I board late enough that there likely won't be space. Checked bag fee not an issue in this equation. My question is whether there's any chance in hell my bag makes the 2nd flight. Any experiences/insights? I haven't flown US in 10 years, if not more.

Thanks!
