TSA delays are not uniform across airports — some have 15-minute lines while others run 45 minutes or longer, and the busiest times shift by day and terminal.
The Transportation Security Administration publishes real-time wait times on its official website at tsa.gov/security-screening-times. You can search by airport code or city name and see current wait times for each security checkpoint, updated throughout the day. The data reflects actual screening times from the past hour, not predictions.
Major hub airports — Atlanta (ATL), Dallas-Fort Worth (DFW), Los Angeles (LAX), Chicago O'Hare (ORD), and New York (JFK, LGA, EWR) — typically have the longest lines during peak travel hours (5 a.m. to 9 a.m. and 4 p.m. to 7 p.m.). Smaller regional airports often move passengers through faster, though they may have fewer open lanes.
Key Takeaways
- TSA publishes live wait times on tsa.gov/security-screening-times, updated hourly for each checkpoint at your airport.
- Peak delays happen between 5 a.m. and 9 a.m., and again between 4 p.m. and 7 p.m., with Friday and Sunday seeing the heaviest traffic.
- Passengers with TSA PreCheck or Clear can use dedicated lanes that typically move 5 to 10 times faster than standard screening.
- Arriving 90 minutes before a domestic flight and 2 hours before an international flight gives you a buffer if your airport is experiencing delays.
How to check wait times before you leave for the airport
Open tsa.gov/security-screening-times in your browser or use the TSA mobile app (available on iOS and Android). Type your airport code or city name into the search box. The page shows each terminal and checkpoint separately, so if your airport has multiple terminals, you can see which one has the shortest line.
Wait times update roughly every hour. If you are checking the night before your flight, the number you see will not match what you encounter the next morning — use it only to understand which airports tend to be busier. Check again 30 minutes before you leave home for a more accurate picture of current conditions.
Some airports also post wait times on their own websites and social media accounts. If your airport has a Twitter account or app, following it can give you real-time alerts when delays spike or when a checkpoint closes temporarily.
Which airports consistently have the longest TSA lines
Atlanta Hartsfield-Jackson (ATL) processes more passengers than any other U.S. airport and regularly reports wait times of 30 to 45 minutes during morning hours. Dallas-Fort Worth (DFW), Los Angeles (LAX), and Chicago O'Hare (ORD) also see frequent delays, especially on weekday mornings and Friday afternoons.
New York area airports — JFK, LaGuardia (LGA), and Newark (EWR) — experience heavy congestion, particularly between 6 a.m. and 8 a.m. and again at 5 p.m. Denver (DEN), Phoenix (PHX), and San Francisco (SFO) also rank among the busier airports, though their wait times tend to be shorter than the largest hubs.
Smaller airports like Austin (AUS), Nashville (BNA), and Fort Lauderdale (FLL) often have wait times under 15 minutes, even during peak hours. If you have flexibility in your travel plans, flying from a regional airport can significantly reduce screening time.
Peak travel times when TSA delays are worst
Weekday mornings between 5 a.m. and 9 a.m. are the busiest period at most airports, as business travelers and families heading to early flights converge on security. The afternoon peak runs from 4 p.m. to 7 p.m., when people return from business trips and evening leisure travel begins.
Fridays and Sundays see the heaviest traffic of the week. Friday mornings and afternoons are congested as weekend travelers depart, and Sunday evenings are packed with people returning home. Mondays through Thursdays are generally lighter, with Tuesday and Wednesday mornings often the quietest times to fly.
Holiday travel periods — the week before and after Thanksgiving, Christmas week, and spring break — create delays even at smaller airports. If you are flying during these windows, plan to arrive at the airport at least two hours before departure, even if your airport normally has short lines.
TSA PreCheck and Clear: faster screening options
TSA PreCheck costs $78 to $85 for five years and lets you use a dedicated security lane where you keep shoes, belts, and light jackets on, and leave laptops and liquids in your bag. PreCheck lines typically move 5 to 10 times faster than standard screening. You explore online, pay the fee, and schedule an in-person appointment at an enrollment center, which takes about 10 minutes.
Clear costs $189 per year (or $15 per month) and uses biometric scanning — your eyes and fingerprints — to skip the document check line entirely. You walk to the front of the line, scan your face or fingerprint, and go straight to the metal detector. Clear works at 50+ U.S. airports and is most valuable at the busiest hubs where the document line itself can take 10 to 15 minutes.
Some credit cards and airline frequent-flyer programs include TSA PreCheck or Clear as a benefit, so check your existing memberships before paying out of pocket. Combining both — Clear to skip the document line and PreCheck to move through the scanner faster — is the fastest option, though it costs roughly $270 per year.
What to do if you arrive at the airport and the line is longer than expected
If you see a wait time longer than 30 minutes when you arrive, look for alternative checkpoints. Many airports have multiple security lanes in different terminals or sections. The TSA website shows wait times by checkpoint, so you can walk to a less busy one if your airport layout allows it.
Ask a TSA officer or airport staff member if any checkpoints are about to open or if one is moving faster than the others. During peak times, airports sometimes open additional lanes without updating the website when ready. If you are running tight on time, let a TSA officer know — they cannot move you to the front, but they can direct you to the fastest-moving lane.
If you miss your flight because of security delays, contact your airline when ready. Most airlines will rebook you on the next available flight at no charge if the delay was caused by TSA screening, though policies vary. Have your boarding pass and a record of the wait time (a photo of the TSA website or a timestamp from when you arrived) to support your case.
Planning your arrival time based on airport size and time of day
For domestic flights at major hub airports during peak hours, arrive 90 minutes early. For the same airports during off-peak times (mid-day, late evening), 60 minutes is usually sufficient. At smaller regional airports, 45 minutes is typically enough even during busy periods.
International flights require more time because of additional document checks and customs screening. Plan to arrive two hours before departure at any airport, and 2.5 hours at the largest hubs during peak travel periods.
If you have TSA PreCheck, you can subtract 15 to 20 minutes from these estimates. If you have Clear, subtract another 10 to 15 minutes. These are buffers, not guarantees — unusual events like staffing shortages or equipment failures can still cause unexpected delays.
Frequently Asked Questions
Can I see TSA wait times for a specific date in the future?
No. The TSA website shows only current and recent wait times, not forecasts. However, you can look at historical patterns: check the same airport on the same day of the week at the same time of day for the past few weeks to estimate what to expect. Tuesday mornings are typically lighter than Friday mornings, for example.
Do TSA wait times include the time to get through the metal detector?
Yes. The published wait time is the total time from when you enter the security line until you collect your belongings on the other side of the scanner. It includes document check, bag screening, and the metal detector or body scanner.
What if my airport is not listed on the TSA website?
Very small airports may not have TSA screening or may share a checkpoint with another nearby airport. Call your airport's main number or check its website to confirm TSA services are available. If TSA screening is not offered, the airport typically handles security through local law enforcement or a private contractor.
Do TSA wait times change during the day?
Yes, significantly. The same airport might have a 15-minute wait at 10 a.m. and a 40-minute wait at 7 a.m. Check the website within 30 minutes of when you plan to go through security for the most accurate picture. Checking the night before tells you only whether that airport is generally busy, not what you will actually encounter.
Is TSA PreCheck worth it if I only fly once or twice a year?
Probably not. At $78 to $85 for five years, PreCheck makes sense if you fly at least four times per year. If you fly less frequently, paying for Clear on individual trips (around $15 per use) is cheaper. Some credit cards and airline programs include PreCheck at no extra cost, so check your existing benefits first.
