Official TSA opens about 90 minutes before the first departure and closes about 30 minutes before the last — this is not a 24-hour passenger hall.

Sunday 4 May 2025 (the day after the Kentucky Derby) was the busiest day on record with 18,500 departing seats. The I-65 central-corridor close of June–July 2026 is over; still give yourself extra curb time on Derby weekend and the first/last banks.

Every airline shares one Level 2 checkpoint. After screening you walk a rotunda into Concourse A or Concourse B — there is no airside train and no second security.

Typical published pattern (Jan 2024 map — trust FIDS): Delta / United / Allegiant on A; American / Southwest / Breeze on B. A west-side 30,000 sq ft checkpoint expansion (10 lanes) is under construction for early 2027.

Book & Bourbon Southern Kitchen (landside, daily 07:00–20:30) is the first stop on Louisville’s Urban Bourbon Trail — Hot Brown plus a real bourbon list.

Airside: Chili’s on A until the last A departure; Smashburger and Coals Artisan Pizza on B from 04:30 until the last B departure; Bourbon Academy Tasting Room in the rotunda 09:00–19:00. Starbucks Evenings in the rotunda opens 03:30.

Live Priority Pass USA has no SDF pin. TARC dropped the passenger terminal from the New TARC Network on 2 Aug 2026 even though flylouisville.com still mentions the bus.

CLEAR+ / CLEAR Mobile are on Level 2 at the main checkpoint (CLEAR Mobile listed 04:00–15:00). PreCheck enrollment by CLEAR is listed 06:00–15:00 near the American counter. Confirm both on clearme.com the morning you fly.
