MLI TSA wait times by hour
TSA screens about 1,100 people a day at Quad Cities International Airport. Its own hour-by-hour counts for Sep 6 to Oct 24, 2026 show when the lines build, and the calculator below turns that into the time to leave home.

TSA's counts, Sep 6 to Oct 24, 2026
Quick answer
Allow up to 30 minutes for security at MLI at its busiest (5–6 AM) and about 15 in the 7–9 PM lull, or 10 and 5 with PreCheck. TSA doesn't publish wait times by airport, so these are planning allowances from its hourly counts of people screened, not live waits. Get to MLI about 1 h 25 min before a domestic flight around 6:30 AM, or 1 h 10 min before one around 8:30 PM, with just a carry-on. Add about 20 minutes to check a bag.

Security at that time: moderate in TSA's counts for an average day, so we allow 20 min. That's a planning allowance, not a live wait. How we calculate this
MLI security wait times by hour
People screened per hour across MLI's checkpoints, averaged over 7 weeks of TSA data (Sep 6 to Oct 24, 2026), and how long to allow for security in each hour. More people means longer lines, though TSA staffs up for the peaks, so read it as when lines build rather than exact waits.
- Quiet
- Moderate
- Busy
- Busiest

Minutes are what we'd allow at that hour's level of traffic: planning allowances, not measured or live waits.
Security at MLI is busiest 5–6 AM, when about 160 people go through every hour: 164 times as many as in the 7–9 PM lull.
Thursday is the busiest day (about 1,200 people) and Tuesday the quietest (about 900). Screening at MLI picks up around 4 AM, lines build from about 4 AM and it winds down after 6 PM.
TSA reports its lines against 30 minutes: on the busy Fourth of July weekend in 2021, 99.7% of travelers in standard lanes waited less than that. So at MLI's busiest hours we plan for 30 minutes in the standard lane and 10 with PreCheck, and less when it's quieter.
How early to get to MLI
How long before departure to reach the airport if you're dropped off at the terminal. Flights around 6:30 AM hit security in its busiest hour; flights around 8:30 PM in a quieter stretch.
| Your trip | Flights around 6:30 AM | Around 8:30 PM |
|---|---|---|
| Domestic, carry-on only | 1 h 25 min | 1 h 10 min |
| Domestic, checking a bag | 1 h 45 min | 1 h 20 min |
| Domestic, carry-on, PreCheck or CLEAR | 1 h 5 min | 1 h |
Parking adds 15 to 25 minutes and returning a rental car about 30; the calculator above adds them for you. Most U.S. airlines close bag drop 45 minutes before domestic departures and 60 before international ones, and on holiday weekends we'd allow another 15 to 25 minutes. How we work these out
MLI security checkpoints
MLI screens departing travelers at one main checkpoint.
| Checkpoint (TSA's name) | Share of travelers | Busy from |
|---|---|---|
| Checkpoint A | 100% | 4 AM |
Getting through MLI security faster
- Fly Tuesday, or at a time that reaches security in the 7–9 PM lull, if you can: MLI's checkpoints see about 0 people an hour then, against 160 at the peak.
- TSA PreCheck or CLEAR: in TSA's 2021 holiday-weekend figures 99% of PreCheck travelers waited under 5 minutes. In our plan it saves about 20 minutes at MLI's busiest hours.
- Checking a bag? The bag drop lines peak at the same hours as security, so add about 20 minutes then, and get there before your airline closes bag drop (usually 45 minutes before a domestic flight).
- On the first flights of the day, expect a line as soon as screening starts: lines at MLI build from about 4 AM.
MLI TSA wait times FAQ
About 1 h 25 min before departure with just a carry-on if your flight leaves around 6:30 AM, when security at MLI is busiest, or 1 h 10 min around 8:30 PM. Checking a bag, allow 1 h 45 min at the busiest times. That's for being dropped off at the terminal; add 15 to 25 minutes to park.
