How long do I need for a layover at Nashville International (BNA)?

We recommend at least 45 minutes for a comfortable connection at Nashville International. The minimum connection time is 40 minutes for domestic flights and 90 minutes for international flights. Transit between terminals takes up to 15 minutes.

Is BNA easy to connect through?

BNA is a mid-size single-terminal airport with four concourses (A, B, C, D) radiating from a central hub area, making most connections a short walk. It's not a major hub for any carrier but has heavy Southwest Airlines traffic and growing international service through Concourse D, which keeps connections generally straightforward outside of peak banks. 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.
