How many security checkpoints does OMA have?

OMA has 2 security checkpoints across 1 terminal (Main). 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.

When is OMA security busiest?

OMA security lines are typically longest during 5–8 AM and 4–7 PM. Outside those windows, wait times drop substantially — check the OMA 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 OMA 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 OMA security checkpoint is fastest?

Use the checkpoint matching your terminal — North (Concourse B) or South (Concourse A); the two buildings are physically separate during the 2025–2027 construction period.

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

What are the top OMA airport security tips?

These tips are specific to Omaha (OMA) and verified against current airport configuration:

• OMA is temporarily split into two separate terminal buildings (North/Concourse B and South/Concourse A) during a 2025–2027 modernization; verify which terminal your airline uses before leaving for the airport.
• The two terminals have no airside post-security connection during construction; entering the wrong building means exiting, re-clearing, and losing your queue position.
• TSA PreCheck is available at Concourse B (North Terminal): Mon–Thu and Sat 4 AM–7 PM, Fri and Sun 4 AM–8 PM.
• Mid-afternoon (2–4 PM) is consistently the quietest security window at OMA; the Monday and Friday 5–8 AM peak windows carry the longest average waits.

Does OMA have TSA PreCheck?

Yes — OMA 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 OMA 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 OMA.

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