I mainly work the florida turns that leave Newark around 1:00p.m. and SUPPOSE to get back into newark around 7:30p.m. I can honesly say that we rarely arrived on-time for our international connectors to make their flights. If we do arrive on-time I am as shocked and excited as everyone else that we go there on scheduled. I can feel the stress levels when we are circling over PHL or DCA for an hour, before we are cleared to go in.
Last week I had this PAX pull me aside before he deplaned in Newark and told me he was considering taking another airline, becuase he was tired of being late every week. I apologized and told him it was Air Traffic control not the airline. And if it's happening to CO it must be happening to every airline that is trying to land at this time. I'm sure he was a new Business traveler

.
But, I suggest you give yourself plenty of time to make your connection.
