It's 6 a.m., your flight boards in 90 minutes, and the security line snakes past the shoe-shine stand, around the corner, and out of sight. You're doing the math in your head, hoping you won't be one of those people sprinting barefoot down the concourse. Nobody enjoys that lottery — which is why airport security wait times are worth knowing before you ever leave for the airport. The numbers vary far more than most travelers realize: depending on where you fly, the typical line can be under four minutes or stretch past twenty. Here's what the latest data says about the fastest and slowest checkpoints in the country — and how to spend less of your life in them.
What TSA's Data Actually Shows About Airport Security Wait Times
The most useful recent picture of airport security wait times comes from a Travel Bulletin analysis of TSA's own data covering the busy summer travel season of 2026 (TSA data, mid-June through mid-August 2026). The study combined two months of wait-time estimates from the TSA's MyTSA app with official passenger-volume figures from the TSA's FOIA Electronic Reading Room, examining the 50 busiest U.S. airports. The full study is published here.
The headline number is reassuring: across those 50 airports, the average wait to get through security was 9.9 minutes. Under ten minutes, on average, at some of the busiest airports in the world. But that average hides an enormous spread. The fastest airport clocked in at just 3.7 minutes; the slowest at 23.1 — meaning passengers at the bottom of the list waited more than six times as long as those at the top. These are averages over thousands of real screenings, not one bad Monday morning.
One caveat worth stating plainly: TSA does not publish an official airport-by-airport ranking of its own wait times, so rankings like this are built from TSA-sourced estimates. Your own experience on a given day will differ. Still, patterns hold up across multiple studies — including a FlightQueue spring 2026 study of 184,012 live observations at 41 airports, which found the median traveler waited under 8 minutes, but with a 6.5-times spread between the calmest and most congested airports.
The Fastest Airports for Getting Through Security
Smaller and mid-sized airports dominate the fast lane. Here's how the quickest checkpoints ranked in summer 2026 (averages across the two-month study period):
- 1. San Antonio International (SAT) — 3.7 minutes. The fastest checkpoint in the country, period. 📍 Map
- 2. Louis Armstrong New Orleans (MSY) — 4.1 minutes. 📍 Map
- 3. William P. Hobby (HOU), Houston — 4.1 minutes (tie). 📍 Map
- 4. Kansas City International (MCI) — 4.2 minutes. 📍 Map
- 5. San Francisco International (SFO) — 4.5 minutes. 📍 Map
- 6. Pittsburgh International (PIT) — 4.6 minutes. 📍 Map
- 7. Southwest Florida International (RSW), Fort Myers — 5.4 minutes. 📍 Map
- 8. Nashville International (BNA) — 5.4 minutes. 📍 Map
- 9. Chicago Midway (MDW) — 5.7 minutes. 📍 Map
- 10. Cincinnati/Northern Kentucky (CVG) — 5.9 minutes. 📍 Map
A few of these deserve a closer look. Kansas City's performance is no accident — its brand-new single terminal, opened in 2023, consolidated scattered old checkpoints into one modern facility, and the payoff shows up in the data. Houston Hobby's 4.1 minutes is striking next to its big sibling George Bush Intercontinental, which averaged 13.6 minutes in the same period — same city, triple the wait, roughly 20 minutes of difference. And San Francisco is the real overachiever: it processed more than 3,200 passengers per hour through security (7th-highest volume in the country) yet kept waits at 4.5 minutes. San Francisco and Kansas City are notable as major airports using private screening contractors under TSA's Screening Partnership Program, and both rank near the top.
The Slowest Airports: Where You'll Wait the Longest
At the other end of the list, the big East Coast and Midwest hubs dominate. These are the ten longest average waits from the same summer 2026 study:
- 1. John F. Kennedy International (JFK), New York — 23.1 minutes. 📍 Map
- 2. Chicago O'Hare (ORD) — 20.2 minutes. 📍 Map
- 3. Newark Liberty (EWR) — 17.9 minutes. 📍 Map
- 4. Ted Stevens Anchorage (ANC) — 16.3 minutes. 📍 Map
- 5. Hartsfield-Jackson Atlanta (ATL) — 14.1 minutes. 📍 Map
- 6. George Bush Intercontinental (IAH), Houston — 13.6 minutes. 📍 Map
- 7. Portland International (PDX) — 13.4 minutes. 📍 Map
- 8. San Diego International (SAN) — 13.2 minutes. 📍 Map
- 9. Dallas-Fort Worth (DFW) — 13.0 minutes. 📍 Map
- 10. Philadelphia International (PHL) — 12.9 minutes. 📍 Map
JFK is in a league of its own. Its 23.1-minute average was the highest in the study, and a separate FlightQueue analysis found JFK's Terminal 4 averaging 29.1 minutes in standard security while Terminal 7 — same airport — averaged just 9.2 minutes. That three-fold gap between terminals at a single airport says a lot: the airport-wide number matters less than which checkpoint you're funneled through.
O'Hare is the one entry travelers should read with an asterisk. This 2026 analysis put it second-slowest at 20.2 minutes, yet a 2024 study using different sensor data once ranked O'Hare the fastest major airport in the country at just over 2 minutes. Wildly different methods, wildly different answers. Treat any ranking as a snapshot, not a verdict — and check current conditions before you fly.
The most surprising slowpoke is Anchorage. Ted Stevens International processed the fewest passengers of any airport in the study — about 517 per hour — yet had the fourth-longest average wait. Size isn't everything; staffing levels, seasonal tourist surges, and limited checkpoint capacity can choke a small airport too. Portland, San Diego, Tampa, and Sacramento tell the same story: waits above the 9.9-minute national average despite below-average passenger volume.
Why Airport Security Wait Times Swing So Much
Passenger volume is the single biggest driver — roughly speaking, every extra 1,000 passengers per hour through security adds about 2.3 minutes of wait, according to the study. That explains JFK, O'Hare, Newark, and Atlanta: LAX, JFK, and O'Hare each push more than 4,200 passengers through security per hour, a pace most airports never approach. But volume alone doesn't explain the full picture, because San Francisco and Orlando move huge crowds with short lines while Anchorage barely moves at all and still stalls.
So what else moves the needle?
- Time of day. The 6–9 a.m. bank of departures is the worst window at nearly every airport; evenings after 8 p.m. are usually calm. The MyTSA app shows historical waits by hour, so you can check your airport's curve before you leave home.
- Day of week. Mondays and Fridays run heavy with business travelers; Sunday evenings surge with weekenders returning. FlightQueue's 2026 data found the day of week alone produced a 36% swing in average waits.
- Terminal and checkpoint choice. At multi-terminal airports like JFK, ATL, and LAX, one terminal's line can be triple another's. If your airport lets you reach any gate from any checkpoint — or lets you walk between terminals airside — picking the emptier checkpoint can save 15–20 minutes.
- PreCheck vs. standard lane. TSA says PreCheck passengers typically wait under 10 minutes, and enrollment has become routine — $78 for five years, and many credit cards reimburse the fee.
- Staffing and disruptions. Understaffed shifts, equipment outages, and high traveler "no-compliance" rates (bags that need re-screening) all slow the belt. These are the unpredictable factors, and they're why even a fast airport can bite you on a holiday.
- Seasonality. The June–August data in this study captures peak summer travel. Thanksgiving, Christmas, and spring break can look very different — always add buffer on holiday weeks.
How to Beat the Line: Practical Tips That Actually Work
Knowing the numbers is half the battle. The other half is using them. Here's what reliably works:
- Get TSA PreCheck or CLEAR — or both. PreCheck ($78 for five years) cuts the standard line down to a dedicated lane with faster procedures: shoes stay on, laptops stay in the bag. CLEAR adds biometric identity verification so you skip the ID check entirely. At airports like JFK and Newark, this combo can easily save 20 minutes. The lanes are least crowded at off-peak hours, so a 9 p.m. departure with PreCheck can mean a near-zero wait even at a busy hub.
- Check live wait times before leaving. The MyTSA app displays estimated waits by airport and time of day, built from historical traveler data. TSA's wait-time information is also linked from the Department of Homeland Security's check-wait-times page. Check it 30–60 minutes before you leave; if the line is spiking, leave earlier or consider a different checkpoint.
- Fly at the right hour. Lines are typically shortest before 6 a.m. and after 8 p.m.; the 7–10 a.m. and 5–7 p.m. windows are the worst at most airports. If you can choose, a midday or late-evening departure is the easiest way to dodge the crowd.
- Pick the smarter checkpoint. At airports with multiple checkpoints feeding the same concourse — Denver, Atlanta's domestic terminal, Dallas-Fort Worth — one line is often much shorter than the one everyone queues at. Walk the extra minute; it's usually worth it. At JFK, remember the Terminal 4 vs. Terminal 7 gap: where you enter matters.
- Arrive with real math, not vibes. The old "two hours domestic, three international" rule is a starting point, not a plan. For a 23-minute-average airport like JFK at morning rush with checked bags, two hours can be tight. For a 4-minute airport like San Antonio at midday, it's generous. Add the airport's average, add time for bag drop and the walk to your gate (gates close 15 minutes before departure), then add a 30-minute buffer for the unexpected.
- Pack like a PreCheck user even if you aren't one. Liquids bagged and accessible, laptop ready to pull, belt and watch off before you reach the belt. The biggest slowdown in any line isn't TSA — it's the traveler repacking a suitcase at the X-ray.
Frequently Asked Questions
What is the average TSA wait time at US airports?
Across the 50 busiest US airports in summer 2026, the average airport security wait time was 9.9 minutes, based on TSA's MyTSA app estimates analyzed by Travel Bulletin. A separate FlightQueue study of spring 2026 found the median traveler waited under 8 minutes across 41 airports. Averages are useful for planning, but individual experiences vary a lot by airport, hour, and day.
Which US airport has the longest security wait times?
New York's JFK International had the longest average wait in the 2026 data at 23.1 minutes, followed by Chicago O'Hare at 20.2 minutes and Newark Liberty at 17.9 minutes. At JFK, waits vary sharply by terminal — Terminal 4 has averaged close to 30 minutes in standard screening while Terminal 7 averages under 10.
How much does TSA PreCheck reduce wait times?
TSA reports that PreCheck lanes typically move in under 10 minutes, and in practice the difference is dramatic at congested airports — travelers with PreCheck plus CLEAR often clear security in 5 minutes or less even at JFK or O'Hare. Enrollment costs $78 for five years, and many travel credit cards cover the fee.
When are airport security lines the shortest?
Lines are usually shortest before 6 a.m. and after 8 p.m., and longest during the morning rush (roughly 7–10 a.m.) and the early-evening bank (5–7 p.m.). Midweek days like Tuesday and Wednesday are generally lighter than Mondays, Fridays, and Sunday evenings. The MyTSA app shows historical wait times by hour for your specific airport.
