Austin (AUS) Security Tips

AUS 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 AUS wait forecast, your drive, and gate-walk into one exact departure time.

How many security checkpoints does AUS have?

AUS has 2 security checkpoints across 2 terminals (Barbara Jordan, South). 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 AUS, letting enrolled members skip the ID-verification queue entirely. See CLEAR at AUS for details.

When is AUS security busiest?

AUS security lines are typically longest during 6–9 AM and 4–7 PM. Outside those windows, wait times drop substantially — check the AUS 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 AUS 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 AUS security checkpoint is fastest?

Barbara Jordan Terminal checkpoint 1 (Gates 1–30) tends to be faster than checkpoint 2 (Gates 31–50+) on peak event weekends.

CLEAR is available at AUS 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 AUS during peak windows, combining both programs is the most effective approach. See CLEAR at AUS for kiosk locations and current status.

What are the top AUS airport security tips?

These tips are specific to Austin (AUS) and verified against current airport configuration:

• AUS has the Barbara Jordan Terminal as its primary facility; rapid Austin growth has driven major gate and concourse expansions being phased in through 2027 — expect periodic layout changes.
• Event peaks are unique to AUS: SXSW (March), ACL Festival (October), and UT football weekends produce sudden volume spikes — arrive 2.5+ hours early during these events.
• CLEAR and PreCheck are available at both main checkpoints; queue times spike notably during major conferences and festivals.
• The South Terminal (Allegiant ultra-low-cost) is a separate facility off the main airport road — verify your terminal at booking to avoid the wrong drop-off entirely.
• Austin traffic on I-35 and SH-71 can add 20–30 minutes during morning rush; check real-time traffic conditions before leaving for the airport.

Does AUS have TSA PreCheck?

Yes — AUS 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 AUS 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 AUS.

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