AD PLACEMENT — CONTEXTUAL
If your itinerary shows a terminal change, budget extra time for the AirTrain ride plus walking to the platform on each end.
United-to-United connections within Terminal C are the easiest, often gate-to-gate without needing to leave the terminal.
Arriving internationally and connecting domestically means collecting bags, clearing customs, rechecking, and going back through security — never cut this close.
Terminal A is the newest and largest but is a distinct AirTrain stop from B and C, so factor that in for airlines like American or JetBlue relocating there.
Precheck lines move fast in Terminal C but Terminal A/B security can back up badly during morning and evening banks.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
The AirTrain monorail links all three terminals plus the rental car and rail station, with trains every few minutes, but the ride plus waiting and walking to platforms can easily take 15-25 minutes terminal to terminal. International arrivals (mostly through Terminal B, some Terminal C) go through CBP and, if connecting onward domestically, must recheck bags and clear a security checkpoint again before reaching their next gate.
