Which DAY security checkpoint is fastest?

DAY 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 DAY. TSA PreCheck at DAY remains the best single upgrade for reducing your security wait.

What are the top DAY airport security tips?

These tips are specific to Dayton (DAY) and verified against current airport configuration:

• DAY has a single central security checkpoint serving both Concourse A and Concourse B — there's no choice of checkpoint, which also means no confusion about which one to use.
• The checkpoint typically operates only about 4am–8pm; if you have a very early departure or a late/redeye arrival outside that window, confirm current hours with the airport before planning a landside wait.
• TSA PreCheck lanes are open at the single checkpoint with typical waits under 5 minutes; CLEAR is not available at DAY.
• As a small, low-traffic airport, overall wait times are short outside the first morning bank — but there is no backup checkpoint if the main lane has an issue, so build in extra buffer just in case.
• Both concourses share the same post-security corridor, so once through screening you can browse either Concourse A or Concourse B's gates and amenities before heading to your own gate.

Does DAY have TSA PreCheck?

Yes — DAY 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 DAY 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 DAY.

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