AD PLACEMENT — CONTEXTUAL
Gates are all within a few minutes' walk, so you rarely need to rush even with a short layover.
If arriving on a seasonal international flight (e.g., from Mexico or the Caribbean), budget extra time for the small federal inspection facility, which can back up during peak leisure season.
BUF has limited daily frequencies on many routes, so missing a connection can mean a multi-hour wait for rebooking.
Security lines are usually light outside of early morning and early evening banks, making short connections comfortable.
There are no interterminal trains or buses to worry about — the whole airport is one building.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
BUF has one compact terminal with two concourses connected by a short indoor concourse walk, so there are no trains, buses, or shuttles required. International arrivals (mainly seasonal leisure routes) use a small federal inspection station near the gates, and passengers continuing onward simply proceed to their next gate after clearing customs.
