Between terminals: JAX has one terminal and one security checkpoint on the mezzanine. After security you walk to Concourse A or Concourse C; no train or shuttle is needed, and you do not clear security again to switch concourses. A third-party map guide puts the walk between the far ends of the two concourses at about 10 minutes. A new Concourse B between A and C is due to open in late January 2027.
Terminals are connected after security, so you can walk between them without re-screening.
Getting to JAX
Rideshare and taxi: Uber and Lyft may drop off on the Upper Departure Curb only. For pickup, request the ride once you are at the curb; App-Based Rides Service signs are on the Lower Arrival Curb next to baggage claim, at Poles 1 and 2.
Transit: Wikipedia lists JTA Route 1 between the airport and downtown Jacksonville. This research could not open JTA's current route pages, and JTA changed Route 1's schedule in June 2026, so check times with JTA before you go.

Garages and surface lots have been filling up in 2026, so check the parking availability page before you leave.
