AD PLACEMENT — CONTEXTUAL
Check your gate assignment as soon as you land since Delta's hub banks often place connecting flights at the opposite end of the tunnel.
Use the moving walkways in the connector tunnel between Concourse A and B to save real time during tight connections.
If arriving internationally, budget extra time for the walk to and through the International Arrivals Facility, plus a second security screening if your next flight is domestic.
TSA PreCheck lanes exist at both concourse security checkpoints and can cut waits significantly during Delta's morning and evening banks.
Delta's Sky Club locations in both concourses are useful if you have a longer layover and want to wait out a delay comfortably.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Concourses A and B are linked by an underground pedestrian tunnel equipped with moving walkways, taking about 12-15 minutes gate to gate under normal conditions. Passengers arriving internationally must exit through the International Arrivals Facility, clear CBP, collect and recheck bags if connecting, then pass back through TSA screening to reach either concourse, adding significant extra time.
