Official map

Maps are updated when terminals are renovated or new concourses open. Terminal 5 at LAX, for example, has been closed since October 2025 for reconstruction — always confirm your terminal from your boarding pass rather than relying on a saved map.
Here is what each terminal or concourse at CHS handles — which airlines fly from it, the gate range, and key amenities to know before you go.
Gates A1–A5 and A2A (6 gates). Serves Delta and Delta Connection. Located on the east side of the terminal building. Delta hub operations.
Gates B1–B10 (10 gates). Serves American, JetBlue, Southwest, United, and Breeze Airways. Located on the west side of the terminal building. Also handles international arrivals through the international processing area.
Internal corridor — single terminal building. Both Concourses A and B share a single security checkpoint area.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at CHS — wait times for people-movers, buses, or security re-screening add up faster than the physical distance suggests. Build the buffer into your Leave-By time, not your gate arrival time.
CHS has three distinct rush periods — 4–7 AM, 11 AM–noon, and 3–6 PM — rather than the usual two. Check real-time wait tools before heading to the airport. The single checkpoint opens at 3:30 AM daily, which is useful for very early departures. Arrive 2 hours before domestic flights; any bottleneck affects all departures simultaneously, especially on Friday and Sunday.
A few habits that prevent last-minute sprints:
