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.
