Security lines at MIA
MIA publishes real-time checkpoint waits on its site but no typical figures. In TSA's hourly screening counts for Mar 15-21 and Sep 13-19, 2026, MIA had two peaks, an early-morning one (about 6-8am) and a larger afternoon/evening one (about 3-7pm). This is unlike most airports, where mornings dominate.
Busiest times: 6:00-8:00am, 3:00-7:00pm, Fridays through Sundays (busiest days in both TSA sample weeks).
Nationally, TSA checkpoints are busiest from 5 to 7 AM local time. See TSA's hourly numbers and the busiest days to fly.
TSA PreCheck: Per MIA's checkpoint list, PreCheck runs during checkpoint hours at Checkpoints 1 (Concourse D), 5, 6, 7 (Central) and 8, 9, 10 (South). Checkpoints 2, 3, 4 and DFIS in Concourse D are not listed with PreCheck. Checkpoint 9 is the only one open 24 hours.
CLEAR: Available at this airport (see terminals below for which checkpoints).
Touchless ID: TSA announced PreCheck Touchless ID at MIA on Feb 10, 2026: North Terminal for American Airlines, Central Terminal for American and Alaska, and South Terminal for Delta and United. Opt in through your airline with your Known Traveler Number and passport on file, and carry a physical ID as backup.

Construction and changes in 2026

MIA tips first-timers miss
- Pick your checkpoint by concourse. MIA's checkpoints are spread across D, E-G and H-J, and only D-E and H-J connect after security, so a walk to the 'wrong' concourse means screening again.
- In Concourse D, only Checkpoint 1 is listed with TSA PreCheck (4:00am-8:15pm), while all Central and South Terminal checkpoints list it. Concourses D and E are connected behind security.
- Checkpoint 9 (South Terminal) is the only one open 24 hours, and most others open between 3:30am and 4:15am, so very early or late flights should check hours
- Concourse D is long. Use the Skytrain on the upper level, which has 4 stations, to reach far gates.
- Paid 'Concierge Powered by CLEAR' curb-to-gate escort service launched in June 2026 for all travelers, from $99 for departures; CLEAR membership is not required
