TSA wait times have improved since their peak in 2016, but they still vary widely by airport and time of day

The longest TSA security lines in U.S. history happened in spring 2016, when some airports reported waits over three hours. That crisis prompted the TSA to hire more officers, open more lanes, and adjust staffing schedules. Today, most airports report average wait times under 15 minutes during off-peak hours. However, "improved" does not mean "short everywhere"—peak travel times at major hubs like Atlanta, Los Angeles, and Chicago still regularly exceed 30 minutes, and holiday periods can push waits back to 45 minutes or more.

The improvement is real but uneven. Smaller regional airports often see waits under 10 minutes year-round. Large hub airports have better staffing than they did in 2016, but they also handle far more passengers. The TSA publishes live wait-time estimates on its website and through the MyTSA app, which show actual conditions at your specific airport on your specific travel date—that is more useful than any national average.

Key Takeaways

  • TSA wait times improved significantly after 2016 but remain longest at major hub airports during peak hours and holidays.
  • The MyTSA app and the TSA website show real-time wait estimates for your airport, updated throughout the day.
  • TSA PreCheck and Clear can reduce your personal wait time, though they do not change the overall line length.
  • Arriving early (two hours for domestic flights, three for international) remains the most reliable way to avoid missing your flight due to security delays.
  • Staffing shortages still occur during holidays and peak summer travel, so conditions can change week to week.

How the TSA measures and reports wait times

The TSA does not publish a single national average. Instead, each airport reports its own data, and the TSA makes those numbers available through two main channels: the MyTSA app (available on iOS and Android) and the TSA website wait times page at tsa.gov. Both show estimated wait times updated throughout the day, usually every 30 minutes.

These estimates are based on actual passenger flow at that airport on that day. They account for the time of day, day of the week, and known travel patterns. If you check at 5 a.m. on a Tuesday, the estimate reflects Tuesday morning traffic at that specific checkpoint. If you check at 4 p.m. on a Friday, it reflects Friday afternoon. This makes the estimates much more useful than a general statement like "Atlanta averages 20 minutes"—because Atlanta at 6 a.m. and Atlanta at 6 p.m. are completely different.

Why some airports still have longer waits than others

Wait time depends on three things: how many passengers are traveling, how many TSA officers are working, and how many security lanes are open. The TSA controls staffing and lanes. Passengers control themselves. At a major hub like Atlanta or Dallas, tens of thousands of passengers move through security every day. Even with more officers than in 2016, the sheer volume means waits can still be substantial during peak hours.

Smaller airports have fewer passengers and proportionally more staffing per traveler, so waits are usually shorter. Regional airports in less-traveled cities often see waits under 10 minutes even during their busiest hours. The trade-off is that smaller airports have fewer flights and may not serve your destination.

Staffing also fluctuates. During summer vacation (June through August) and major holidays (Thanksgiving, Christmas, spring break), passenger volume spikes and some TSA officers take time off. This combination can push waits back up temporarily. The TSA tries to manage this by scheduling extra officers during known peak periods, but it is not always enough.

TSA PreCheck and Clear: what they actually do

TSA PreCheck costs $78 to $85 for five years and lets you use a dedicated security lane with less stringent screening rules—you can leave shoes, belts, and light jackets on, and laptops stay in bags. Clear costs $179 per year and uses biometric scanning (fingerprint or iris) to skip the ID-check line entirely, moving you straight to the body scanner. Both programs reduce your personal wait time, but they do not reduce the overall line or the number of passengers the airport must process.

If you travel frequently for work or take multiple trips per year, PreCheck often pays for itself in time saved. Clear is more expensive and useful mainly if you travel very frequently or have a low tolerance for waiting. Neither program guarantees you will not wait—if the security lane itself is backed up, you still wait, just in a shorter line. During extreme peak times (major holiday mornings), even PreCheck and Clear lines can exceed 15 minutes.

What changed at TSA checkpoints since 2016

The TSA hired hundreds of new officers after the 2016 crisis and has maintained higher staffing levels since. It also added more security lanes at major airports and adjusted when lanes open and close to match passenger flow better. For example, instead of opening all lanes at 5 a.m. regardless of demand, airports now open lanes based on real-time passenger counts.

Technology also improved. Newer X-ray machines can screen carry-on bags faster, and some airports now use automated screening lanes that require less hands-on officer time. However, these upgrades roll out slowly and unevenly—a major airport might get new equipment while a smaller one does not.

The TSA also made staffing more flexible. Officers can be reassigned between checkpoints within an airport based on where lines are longest, rather than being locked to one lane all day. This helps balance waits across multiple checkpoints, though it requires more coordination and training.

How to check wait times before you travel

Open the MyTSA app or visit tsa.gov/travel/security-screening/wait-times on your phone or computer. Search for your airport by name or airport code. The page shows current estimated wait times for each security checkpoint at that airport. Some airports have multiple checkpoints (Terminal A, Terminal B, or Concourse 1, Concourse 2), so check which one your airline uses.

Check the wait time on the morning of your flight, not the night before. Wait times change throughout the day and vary by day of the week. A Tuesday morning wait is usually much shorter than a Friday afternoon wait at the same airport. If you see a wait time over 30 minutes, plan to arrive even earlier than you normally would, or consider using PreCheck or Clear if you have it.

The TSA also publishes historical wait-time data for each airport, showing average waits by hour and day of the week. This can help you plan future trips—if you know that your airport is always busiest on Friday mornings, you can book a flight at a different time.

Peak travel times and seasonal patterns

TSA wait times follow predictable patterns. The busiest travel days are the Wednesday before Thanksgiving, the day before Christmas, and the Sunday after both holidays. Summer Fridays and Sundays are consistently busy. Early morning (5 a.m. to 7 a.m.) is usually the slowest time, and late afternoon (3 p.m. to 6 p.m.) is usually the busiest.

If you have flexibility in when you travel, flying on a Tuesday, Wednesday, or Thursday morning will almost always mean shorter waits than flying on a Friday, Saturday, or Sunday afternoon. If you must travel during peak times, arriving three hours early for a domestic flight (instead of the standard two hours) gives you a buffer if security is slower than expected.

Frequently Asked Questions

Are TSA lines shorter now than they were in 2016?

Yes. The TSA hired more officers and opened more lanes after the 2016 crisis. Most airports now report average waits under 15 minutes during off-peak hours. However, peak times at major airports can still exceed 30 minutes, and holiday travel can push waits back to 45 minutes or more.

How accurate are the wait times shown in the MyTSA app?

The estimates are based on real passenger flow at that airport on that day, updated every 30 minutes. They are usually accurate within 5 to 10 minutes, but they reflect conditions at the moment you check. If you check at 6 a.m., the estimate is for 6 a.m. traffic; if you check 30 minutes later, conditions may have changed.

Does TSA PreCheck may provide I will not wait?

No. PreCheck puts you in a shorter, faster-moving lane, but you still wait if that lane is backed up. During extreme peak times, even PreCheck lines can exceed 15 minutes. PreCheck is most valuable if you travel frequently and want to avoid the standard screening process.

What time of day has the shortest TSA lines?

Early morning (5 a.m. to 7 a.m.) is usually the slowest time at most airports. Late afternoon (3 p.m. to 6 p.m.) is usually the busiest. If you have a choice, booking an early morning flight will almost always mean shorter security waits.

Can I check wait times for my airport before I book my flight?

You can check historical average wait times by hour and day of the week on the TSA website, which helps you plan. However, real-time wait times are only available on the day of travel. Use historical data to choose a flight time, then check the MyTSA app on the morning of your trip for actual conditions.
