Raleigh–Durham (RDU) Security Tips

RDU has 2 security checkpoints with TSA PreCheck lanes and CLEAR biometric lanes. Security is busiest 6–9 AM and 4–7 PM. Use the Leave-By Time calculator to fold the modeled RDU wait forecast, your drive, and gate-walk into one exact departure time.

How many security checkpoints does RDU have?

RDU has 2 security checkpoints across 2 terminals (1, 2). TSA PreCheck dedicated lanes are available, giving members a faster, bin-free screening experience. PreCheck is open at the main checkpoints during regular screening hours, though an individual lane can close off-peak. CLEAR biometric kiosks are also deployed at RDU, letting enrolled members skip the ID-verification queue entirely. See CLEAR at RDU for details.

When is RDU security busiest?

RDU security lines are typically longest during 6–9 AM and 4–7 PM. Outside those windows, wait times drop substantially — check the RDU wait forecast for the current picture before you head out. General guidance:

• Domestic flights: arrive at least 2 hours before departure; 2.5 hours during peak periods.
• International flights: arrive at least 3 hours before departure to cover check-in, security, and any customs pre-clearance.

Not sure when to leave? The Leave-By Time calculator uses the modeled RDU wait forecast, real-time traffic, and your gate-walk distance to give you an exact departure time. Also see how early to arrive at the airport for a full breakdown by flight type.

Which RDU security checkpoint is fastest?

Terminal 2 checkpoint (Gates D/E) is the primary facility and typically faster than Terminal 1 (Gates A/B) on American-heavy mornings.

CLEAR is available at RDU and can be stacked with TSA PreCheck for the fastest path through security: CLEAR handles the biometric ID verification, PreCheck handles the bin-free lane. If you frequently travel through RDU during peak windows, combining both programs is the most effective approach. See CLEAR at RDU for kiosk locations and current status.

What are the top RDU airport security tips?

These tips are specific to Raleigh–Durham (RDU) and verified against current airport configuration:

• RDU has two terminals (Terminal 1 and Terminal 2) connected by the RDU Express shuttle bus; each has its own security checkpoint.
• Terminal 2 is the larger, more modern facility handling American, Delta, and United; Terminal 1 primarily serves Southwest and moves faster on most days.
• RDU is a growing tech-corridor airport serving the Research Triangle; Monday mornings and Thursday/Friday evenings are driven by business travelers and can back up quickly.
• CLEAR kiosks are at Terminal 2; PreCheck is available at both terminals.
• Summer months see conference season overlap with leisure travel peaks — book flights midweek and allow a full 2-hour pre-departure buffer during June–August.

Does RDU have TSA PreCheck?

Yes — RDU has TSA PreCheck lanes at its security checkpoints. PreCheck members keep shoes, belts, light jackets, laptops, and 3-1-1 liquids packed, and pass through a dedicated screening lane. Membership costs $85–$100 for five years and includes a Known Traveler Number (KTN) you add to every booking.

See live PreCheck wait times and current lane status on the RDU TSA PreCheck page. That page also covers which terminals have a PreCheck lane, enrollment locations, and how PreCheck compares to CLEAR and Global Entry at RDU.

Global Entry interviews can be completed at RDU itself — via an on-site enrollment center or Enrollment on Arrival after an international flight — and membership includes TSA PreCheck. See Global Entry at RDU for locations and hours.
