Connecting flight after I return to PHL is now 7 hours and 10 minutes after arrival of my flight from FCO, but there is a flight from PHL that departs exactly one hour after scheduled arrival in PHL.

Since I have run pretty fast before to get the earlier flight, I wonder what the official time allowed is now. Is one hour just out of the question? The last time I ran to get that flight, I made it, but the flight was full, and I wish I could just book it.
