AD PLACEMENT — CONTEXTUAL
The entire airport is a single small terminal building with a handful of gates just steps from security and check-in, so there is no shuttle, train, or bus needed between any areas. There is no true international arrivals or connections infrastructure since IAG has no international service, so re-screening scenarios simply do not apply here.
