Tips for 45 min Connections
Stay within McNamara Terminal whenever possible since the tram makes A-B-C connections extremely fast.
If connecting to or from a North Terminal airline like American, Southwest, or United, budget extra time for the shuttle bus and a fresh security screening.
Delta's hub operates in banks, so mid-morning and early evening see the tightest concourse crowds and tram queues.
International arrivals at McNamara go through a well-organized but sometimes slow Federal Inspection Services process, so build in buffer for that step.
Use the moving walkways and overhead signage in McNamara if you'd rather walk than wait for the tram.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
Within McNamara Terminal, the Express Tram glides above the concourses connecting A, B, and C in just a few minutes, and moving walkways line the concourses for those who skip it. Getting to or from the North Terminal requires an inter-terminal shuttle bus (5-10 minutes plus wait time) and a full walk through security again since it's landside-connected only. International arrivals at McNamara clear Federal Inspection Services before continuing to connecting flights.
