Tips for 40 min Connections
Check your gate assignment as soon as you land since the four concourses meet at a central point, making cross-terminal walks quick but not instant.
If arriving internationally, budget extra time for the CBP process at the Concourse D Federal Inspection Station, especially during morning transatlantic arrival banks.
Southwest passengers connecting between Southwest flights benefit from BNA's compact layout and frequent departures if you miss a tight window.
Security lines can spike around early morning and late afternoon banks, so use TSA PreCheck if eligible to save meaningful time.
Restaurants and shops are concentrated near the Rotunda, so a short layover still gives easy access to food without a long detour.

Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
All concourses connect through the central Rotunda via covered walkways, with no trains or shuttles needed anywhere in the terminal. International arrivals deplane at Concourse D and pass through Federal Inspection Services (CBP) before re-entering the sterile area to connect onward; connecting passengers arriving internationally do not need to re-clear security if continuing to a domestic flight after CBP.
