Terminal layout & organization
Charleston International Airport (CHS) is compact and easy to understand: you’ll use one central landside area (ticketing, security, and baggage claim) and then fan out to two concourses on the airside: Concourse A and Concourse D. Most passenger services—check-in counters, rental-car desks, and baggage claim—are centralized, so you don’t need to “pick a terminal” before security in the way you might at larger airports. After screening, follow overhead signs to your gate in Concourse A or Concourse D. While CHS handles both domestic and some international service, the concourse assignment is primarily about gate availability and airline scheduling rather than separate, fully independent terminals.
Navigation between Concourse A and Concourse D
Getting between Concourse A and Concourse D is done on foot via connected airside corridors; there’s no train or shuttle. If you realize you’re in the wrong concourse, you can typically walk between them in about 5–10 minutes at a normal pace (longer if you stop for food or are traveling with kids). Wayfinding is straightforward: look for large overhead signs marked “Gates A” or “Gates D”, and confirm your gate number on the nearest flight information display once you enter the correct concourse. If you’re short on time, avoid leaving the secure area—ask staff near the corridor junction for the quickest route to your gate.
Traveler-specific tips
- Families: CHS is stroller-friendly with level pathways and elevators between levels. If you’re traveling with a baby, ask any airport or airline staff member to direct you to the nearest nursing/lactation room or family restroom location once you’re in Concourse A or Concourse D. To minimize stress, plan to arrive at your concourse early—amenities are limited compared with large hub airports.
- Business travelers: For a smoother morning departure, use your airline app to confirm which concourse you’re departing from before you get in line. Seating with workable space is most plentiful near central gate areas; if you need a quieter spot, walk a few gates away from the busiest food options in Concourse A.
- Travelers with disabilities: Both Concourse A and Concourse D are designed for step-free travel, with elevators, accessible restrooms, and clearly marked assistance points. Request wheelchair or mobility help through your airline in advance, then re-confirm at check-in.
- Budget travelers: Bring an empty bottle—water bottle filling stations and fountains are typically available post-security. Charging can be competitive at peak times, so plug in as soon as you reach Concourse A or Concourse D.
Practical information
Wi-Fi is available throughout CHS in both Concourse A and Concourse D; connect as soon as you clear security so you can pull up your digital boarding pass and gate updates. Power outlets are most commonly found near seating clusters and along walls near gate areas—if you need to work, scout outlets before you settle in. For in-person help, use airline service counters near your departure gates and look for airport staff in the central post-security area for general directions. If you notice detours, closed seating sections, or temporary hallway barriers, follow posted signs—they usually indicate short-term maintenance or periodic improvements that can slightly change the quickest walking route between Concourse A and Concourse D.
