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 SLC handles — which airlines fly from it, the gate range, and key amenities to know before you go.
SLC has one integrated terminal building with no separate Terminal 1/Terminal 2. Concourse A is Delta Air Lines' primary hub, with 47 gates (A1–A35, including A27/A29/A31/A33/A35 as odd-numbered additions). Delta operates the vast majority of flights here (~45% of all SLC departures). International arrivals and departures are processed through Concourse A. The Delta Sky Club is located post-security on Level 2 of Concourse A.
Concourse B hosts all non-Delta carriers: Southwest Airlines, American Airlines, United Airlines, Alaska Airlines, JetBlue Airways, Frontier Airlines, Hawaiian Airlines, Avelo Airlines, Sun Country, Air Canada, and WestJet. Current gate count is approximately 31–36 gates (B1–B24 and beyond), expanding to 47 gates by October 2026 as Phase 4 construction completes. The concourse is east of the central plaza and growing eastward.
Two underground pedestrian tunnels connect both concourses airside — no re-clearing security for domestic connections. The primary link is the River Tunnel (also called Central Tunnel), a 900-foot passageway decorated with a blue river-themed LED art installation and equipped with 5 moving walkways; it opened October 22, 2024, and takes about 5–7 minutes to traverse. A second Mid-Concourse Tunnel connects near gates A13–A15. Both are signed throughout the terminal.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at SLC — 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.
Use the River Tunnel (Central Tunnel, opened Oct 2024) for all connections between Concourse A and Concourse B — it has 5 moving walkways, cuts the walk to roughly 5–7 minutes, and is clearly signed from both concourses. Note that SLC has only one terminal building (no inter-terminal buses or trains), so all connections are airside pedestrian walkways; only international arrivals must exit the secure zone.
A few habits that prevent last-minute sprints:

Your boarding pass shows the exact gate. Open your airline app about two hours before departure — gate assignments sometimes change after check-in closes. Look for departure boards throughout the terminal for real-time gate information.
