Concourse B Guide: Jacksonville Airport (JAX)

Terminal Overview

Concourse B at Jacksonville International Airport (JAX) is currently closed and not used for passenger flights. JAX operates from a single main terminal with two active concourses—Concourse A and Concourse C—each with 10 gates. Concourse B is planned for rebuilding in the future when passenger demand increases, so if you’re looking for gate info, dining, or lounges “in Concourse B,” you’ll actually be using A or C today.

The good news is that JAX is easy to navigate: departures are on Level 2, arrivals/baggage claim on Level 1, and the airside concourses branch off from the same central area after security. The overall experience is straightforward—short walks, clear signage, and plenty of services concentrated in the central terminal and the two operating concourses.

Airlines & Destinations

  • Concourse A (active): primarily Delta Air Lines (SkyTeam), JetBlue (non-aligned), and United (Star Alliance, including United Express/seasonal service).
  • Concourse C (active): primarily American Airlines (Oneworld, including American Eagle), Southwest (non-aligned), plus carriers such as Avelo, Frontier, and Sun Country (seasonal).

Since Concourse B is closed, you won’t find dedicated B-gate airlines. Instead, check your boarding pass for A1–A10 or C1–C10. From JAX you’ll typically see frequent domestic service to major hubs and popular routes across the Southeast, Northeast, and Midwest (with seasonal options depending on airline schedules).

Layout & Navigation

JAX has one terminal with a central post-security area (often described as a mezzanine) that feeds into the two active concourses. Concourse B is not part of the current passenger flow, so you’ll route to either Concourse A or Concourse C after clearing security.

  • Gate ranges: Concourse A = A1–A10; Concourse C = C1–C10. (No active B gates.)
  • Security: Screening is positioned at the entrance areas leading to the concourses, with TSA PreCheck available. If you’re unsure where to enter, follow signs for your concourse letter.
  • Walking times: Most walks inside JAX are short. Plan roughly 5–10 minutes from the central post-security area to the far end of either concourse, and about 10–15 minutes to go from a far A gate to a far C gate at a comfortable pace.
  • Connections: You can walk between Concourses A and C airside; no shuttle or train is needed. If you accidentally head toward the wrong concourse, you can usually correct it with a simple walk back through the central connector.

Amenities & Services

Because Concourse B is closed, amenities you may have expected there are concentrated in the main terminal and in Concourses A and C. Pre-security, you’ll find the core services: ticketing upstairs (Level 2), baggage claim downstairs (Level 1), and a central public area with shops, restaurants, and local culture/aviation-themed displays.

  • Lounges: A dedicated Delta Sky Club is located in Concourse A. Concourse C features a multi-airline passenger club located behind the airside food court.
  • Food & shopping: Both active concourses have a mix of quick meals, coffee/snacks, and travel essentials. If you want the most choice, linger near the central post-security area where options cluster before the concourse corridors.
  • Business needs: Expect standard airport conveniences—WiFi, seating, and spots suitable for laptop use—best found in the central airside area and near larger gate holdrooms.
  • Family amenities: For the smoothest experience, aim to settle near larger clusters of restrooms and seating (typically closer to the central connector). If you need a quieter corner for feeding or calming kids, the ends of concourses are often less hectic than the central zone.
  • Accessibility: The single-terminal, single-level concourse design makes mobility simpler. Elevators/escalators connect Level 1 and Level 2, and gate areas are generally step-free once you’re airside.

If you’re meeting someone or waiting landside, note that the main terminal also hosts services like information desks and a USO lounge (landside), which can be helpful for eligible travelers.

Practical Tips

  • Don’t hunt for Concourse B: If an old blog or map mentions B gates, ignore it—confirm your gate as A# or C# in the airline app or airport monitors.
  • Best for long layovers: Stay near the central airside connector so you’re close to the widest spread of food and can pivot quickly to either concourse when your gate posts.
  • Quietest places: Walk toward the far ends of Concourse A (near A10) or Concourse C (near C10). These areas are often calmer than the central food court zone.
  • Power outlets: Look first around gate seating clusters and along shared charging counters in holdrooms. If outlets are taken, check seating along the concourse edges and near support columns.
  • WiFi: JAX offers airport WiFi; connect as soon as you clear security so you can stream, re-check gates, and watch for delay notifications while you walk.

Bottom line: treat “Concourse B” as a historical reference for now. For today’s travel, everything you need will be in Concourse A or Concourse C, with easy walking connections between them.
