AD PLACEMENT — CONTEXTUAL
TRI has essentially no true connecting itineraries since it's a small spoke airport, so if you're routing through here you're likely misreading your itinerary and actually connecting at your hub city instead.
The entire terminal is one short concourse, so even a tight layover is easy to manage on foot.
Security lines are minimal outside of the early morning and late afternoon banks tied to regional jet departures.
There is no need to worry about long walks, trains, or terminal transfers of any kind at TRI.
If you do have a rare same-plane or same-day turn connection here, gate agents and staff are easy to find for quick assistance.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
There is only one small terminal building with a single concourse, so all gates are reached on foot within a couple of minutes. There is no shuttle, train, or inter-terminal transfer of any kind, and no security re-screening is needed since passengers simply walk between adjacent gates.
