Tips for 1½ hr Connections
If connecting from an international flight, budget extra time for the CBP/immigration line, which can run 30-60+ minutes even for US citizens during peak arrival banks.
Check which terminal your next flight departs from as soon as you land — Terminal 4 (Delta/SkyTeam) and Terminal 8 (American/oneworld) are the largest and can have long internal walks.
Use the AirTrain rather than trying to walk between non-adjacent terminals; it's free once inside the airport perimeter.
JetBlue (Terminal 5) and Delta (Terminal 4) connections are generally smoother since both have larger, more efficient rebooking and gate networks.
Build in a buffer for any itinerary requiring an international-to-international connection, since there's no sterile transit and you'll effectively re-enter the airport from scratch.

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 AirTrain JFK light-rail system connects all terminals and runs every few minutes, with a full loop taking about 15-20 minutes depending on stops, but add walking time at each end plus waiting. Terminal 1 and Terminal 4 have an internal walking connector, and Terminal 7/8 are within walking distance, but most passengers should plan on the AirTrain for terminal changes. Any international arrival connecting onward — domestic or international — must exit through CBP, reclaim and recheck bags at the terminal's transfer desk, then clear TSA security again before reaching the gate area.
