Airport security wait times can vary widely. Flight departure waves, staffing levels at checkpoints, weather disruptions, and equipment hiccups can all disrupt the flow—and can be the difference between breezing through in five minutes or standing in a line that snakes through the terminal.
Transportation Security Administration (TSA) lines have been especially unpredictable in recent weeks, following a partial government shutdown during which thousands of TSA employees were required to work without pay, with some calling in sick. The staffing disruptions have contributed to longer screening lines at several airports just as spring travel is beginning to ramp up—at times stretching for hours, including reported waits of up to 3.5 hours at William P. Hobby Airport in Houston.
While disruptions like government shutdowns can exacerbate the problem, fluctuating security lines are hardly unusual. If you’re wondering how busy the checkpoint might be before heading to the airport, a few tools can help you estimate wait times in advance.
Check the MyTSA app
One of the simplest tools is the MyTSA app, the official app from the Transportation Security Administration. The app combines crowd-sourced reports from travelers with historical screening data to estimate how long security lines are at airports across the United States. Travelers can submit their own wait times after going through security, and the app aggregates those reports to provide a general estimate of how busy the checkpoint is.
Unfortunately, during the partial government shutdown, the app isn’t actively being monitored, but users can also look up typical wait times by day of the week and time of day, which can help identify traditional rush periods—such as early morning departure banks at major hubs.
Travelers can also check which security programs—such as TSA PreCheck lanes—are open at their airport, review tips about prohibited items before heading to the checkpoint, and even text questions to TSA (this last tool is also temporarily disabled during the partial shutdown).
Because wait-time estimates rely partly on traveler submissions, they’re best treated as rough guides rather than precise predictions. Security lines can still shift quickly if a large group of passengers arrives at once or if checkpoint staffing changes during the day.
Look at your airport’s website
Many airports also publish estimated checkpoint wait times on their websites. For example, Denver International Airport and Hartsfield–Jackson Atlanta International Airport, two of the busiest airports in the country, both offer real-time or near-real-time estimates based on passenger flow through their security checkpoints.
These estimates are typically generated using a mix of real-time sensors, operational data, and historical trends. While they’re not always 100 percent accurate, they can offer a helpful snapshot of how crowded the security area is at a given moment.
Check social media and local news outlets
Airports will also sometimes issue travel advisories—via their websites or social media channels—when security lines are expected to be longer than usual due to weather disruptions, holiday travel, or staffing shortages. Local news outlets will also often report on major airport issues, including TSA lines that are stretching longer than is typical.
Use flight-tracking platforms
Flight-tracking websites and apps can also provide clues about how busy an airport might be.
Platforms such as FlightAware and Flightradar24 don’t track security lines directly, but they show flight delays, airport congestion, and departure patterns. If you see delays starting to pile up at a given hub, that can help you gauge how busy the airport might be overall—and whether disruptions could ripple into longer security lines.
