AD PLACEMENT — CONTEXTUAL
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.
