Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
The Plane Train automated people mover runs underground between all seven concourses, departing every 1–2 minutes. A full end-to-end ride takes about 10 minutes.
