• International flights: arrive at least 3 hours before departure to cover check-in, security, and any customs pre-clearance.

Which LEX security checkpoint is fastest?

LEX operates a single main checkpoint, so all passengers enter the same security lane. TSA PreCheck is the primary tool for faster throughput here — members keep shoes, belts, and laptops packed.

CLEAR is not currently available at LEX. TSA PreCheck at LEX remains the best single upgrade for reducing your security wait.

What are the top LEX airport security tips?

These tips are specific to Lexington (LEX) and verified against current airport configuration:

• LEX has a single security checkpoint on Level 2 serving both Concourse A and Concourse B — there is no choice of checkpoint, but lines are typically short outside of weekday mornings and holidays.
• TSA PreCheck lanes are available at the checkpoint; CLEAR is not offered at LEX as of this writing.
• The checkpoint generally operates daily from about 4:00am until roughly 8:30–9:30pm, tied to the day's flight schedule — if your flight is delayed, arrive based on the original departure time since the checkpoint may still close on schedule.
• Airport guidance recommends arriving at least 90 minutes before departure; because the terminal is compact, that buffer is more about check-in and parking than a long security line.
• Complimentary Hidden Disabilities Sunflower lanyards are available 24/7 at a stand in front of the checkpoint for travelers who want to discreetly signal a non-visible disability to TSA staff.

Does LEX have TSA PreCheck?

Yes — LEX 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 LEX 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 LEX.

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