How many security checkpoints does CHS have?

When is CHS security busiest?

CHS security lines are typically longest during 4–7 AM, 11 AM–noon, and 3–6 PM. Outside those windows, wait times drop substantially — check the CHS 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 CHS 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 CHS security checkpoint is fastest?

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

What are the top CHS airport security tips?

These tips are specific to Charleston (CHS) and verified against current airport configuration:

• CHS has three distinct daily rush windows — pre-dawn, late morning, and late afternoon — rather than the usual two; check real-time wait tools before heading to the airport.
• The single checkpoint opens at 3:30 AM daily — useful for very early Southwest or Delta departures; plan accordingly if your flight boards before 5 AM.
• Any bottleneck at the shared checkpoint affects all departures simultaneously — add extra buffer on Fridays and Sundays, the two busiest travel days.
• Tuesday and Wednesday consistently have the lightest loads; arriving midweek cuts average wait times by 15–20 minutes compared to weekend peaks.

Does CHS have TSA PreCheck?

Yes — CHS 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 CHS 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 CHS.

CHS does not host a Global Entry enrollment center or Enrollment on Arrival, so the interview has to be completed at another location — but membership still pays off here, since Global Entry includes TSA PreCheck for the CHS PreCheck lanes. Details on Global Entry at CHS.
