Tips for 45 min Connections
JAX is not a true hub, so most itineraries routing through it are rare — double-check your routing if you see a JAX connection.
The single terminal means gate-to-gate walks rarely exceed 10 minutes, even between the farthest concourse ends.
If you have TSA PreCheck, the dedicated lane can cut security time to a few minutes even during peak periods.
Limited international flights (mainly to the Bahamas) go through a small Federal Inspection Station, so budget extra time if arriving from abroad.
Food and gate amenities are limited, so if you have a long layover, plan to eat before your first flight since options near far gates are sparse.

Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
JAX has a single terminal building with two concourses, A and C, connected by a central atrium and corridor that passengers walk through directly. There is no train or shuttle needed anywhere in the airport, and security is a single central checkpoint serving both concourses, so domestic-to-domestic connections typically don't require re-screening.
