• 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 ILM 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 ILM security checkpoint is fastest?

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

What are the top ILM airport security tips?

These tips are specific to Wilmington (ILM) and verified against current airport configuration:

• ILM has a single main security checkpoint serving the entire terminal — there is no alternate checkpoint to route around a line if it's busy.
• TSA PreCheck lanes are available at the main checkpoint; CLEAR is not currently offered at ILM.
• Ticket counters and TSA screening typically begin around 4am–4:15am to cover ILM's earliest departures — if you're booked on a first-wave flight, don't expect the checkpoint to open much earlier than that.
• Security lines run longest in the morning and around holidays; the airport itself recommends arriving at least 1.5–2 hours before departure.
• Because ILM is compact with all nine gates close together, budget your extra time for the checkpoint rather than for walking afterward — every gate is a short walk from security.

Does ILM have TSA PreCheck?

Yes — ILM 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 ILM 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 ILM.

ILM 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 ILM PreCheck lanes. Details on Global Entry at ILM.
