AD PLACEMENT — CONTEXTUAL
Check whether your connection stays within Terminal 2 (where most major carriers operate) since that avoids the shuttle and re-screening entirely.
If your connection spans Terminal 1 and Terminal 2, budget extra time for the AirLink shuttle plus a fresh security line.
American Airlines, Delta, United, and JetBlue mainline operations are concentrated in Terminal 2, while Southwest and Allegiant primarily use Terminal 1.
International arrivals clear Customs and Border Protection in Terminal 2 before any onward connection, so build in extra buffer on inbound international flights.
TSA PreCheck lanes exist in both terminals and can meaningfully cut wait times during the morning and evening peaks.

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.
The free RDU AirLink shuttle bus connects Terminal 1 and Terminal 2 landside, with a ride time of about 8-10 minutes plus waiting, since the terminals are not connected airside. Because the shuttle operates outside security, any connection between terminals requires exiting one checkpoint and clearing security again at the other, which is the main pinch point for tight connections. Within a single terminal, gates are reachable on foot in 5-10 minutes.
