Official map
Buffalo official terminal map — airport authority website
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 BUF handles — which airlines fly from it, the gate range, and key amenities to know before you go.
All 24 gates sequentially numbered in one corridor. Serves Southwest, American, Delta, JetBlue, United, Frontier, and Sun Country. No concourse separation — compact and straightforward to navigate. Single checkpoint on the departure level with TSA PreCheck and CLEAR Plus available.
Single terminal — all gates are in one building with no inter-terminal transit required.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at BUF — 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.
BUF's compact single-terminal layout means minimal walking once through security, so 90 minutes before a domestic departure is typically sufficient. TSA PreCheck and CLEAR Plus are both available; CLEAR + PreCheck together consistently delivers sub-5-minute processing even during the 6–9 AM and 4–7 PM peaks when standard lines can reach 25–30 minutes.
