How TSA Tracker works
Use the live number for what is happening now, and the trend for when to leave. The airport pages add the specific notes, maps, and terminal guidance that make the reading useful.
Check the live number
If the page shows a live feed, that reading comes from the airport’s own published system rather than a guess or crowd report.
Read the trend
The chart shows whether the line is at a normal lull or entering a peak window before you leave home.
Open the airport page
Use the airport page for terminal notes, PreCheck context, and official airport links that matter for that specific trip.
Best place to start
If you are comparing options or trying to understand the numbers, these pages explain the site better than the homepage alone.
Is a live reading enough?
Use the live number to decide if you need extra buffer, then confirm the trend before you leave. That is the safest way to use the site.
What if my airport is not live?
Use the airport index and methodology pages first. If we do not show an airport as live, we do not want to pretend the source is stronger than it is.
Where should I click next?
Airport pages are the main value. Guides and methodology explain how to use the readings and what the limits are.

Want to cut security time permanently? Compare TSA PreCheck, CLEAR, and the best travel cards →
- Check your airport's current wait time and 12-hour trend 30–60 minutes before leaving.
- Confirm your terminal and security entrance before rideshare drop-off or parking.
- If your airport shows lane-level data, compare Standard vs PreCheck before choosing a checkpoint.
- Keep ID, boarding pass, and carry-on electronics accessible to reduce secondary screening delays.
- If your travel window overlaps morning (5–9 AM) or afternoon (4–7 PM) peaks, leave earlier than usual.

About LAS TSA Security Wait Times
TSA Tracker provides live TSA checkpoint wait times for Harry Reid International (LAS). Data is pulled directly from official LAS airport security feeds — not estimates — and refreshes every ~2 minutes. Use the live data and 12-hour history chart above to plan when to head to the airport.
Tips for LAS travelers
- Green = short wait (under 15 min). Yellow = moderate. Red = long lines — arrive earlier than planned.
- Use the history chart to spot peak hours at LAS and choose a less busy time to pass through security.
- TSA wait times at LAS refresh every ~2 minutes — reload for the very latest reading.
- If LAS shows PreCheck or CLEAR lane data, those lines are almost always shorter than the standard lane.
- LAS shows separate live wait-time widgets for Terminal 1 and Terminal 3 checkpoint groups, so compare both before choosing where to enter.
- The airport page embeds the live Zensors widget directly, which makes the current reading useful for same-day planning rather than just a historical estimate.
- If one terminal group is calm and the other is backed up, use the airport's checkpoint grouping and your airline terminal to pick the better entry point.
How to use this page
- Use the live checkpoint cards first to judge current conditions, then use the history chart to see whether the line is following a normal peak.
- Confirm your terminal or airline before heading to security, since many airports on TSA Tracker have different wait patterns by checkpoint or terminal.
- Use the official airport links below if you need terminal maps, airport-specific security guidance, or the airport's own traveler tools.
What matters specifically at LAS
This page adds LAS-specific terminal context, airline routing notes, and 3 official airport resources so the wait-time reading is actually usable for a same-day trip.
- This page is currently backed by 8 live LAS checkpoint readings, so the terminal and checkpoint spread matters more than a single airport-wide average.
- Harry Reid publishes live security wait times directly on its official airport site.
- The page exposes both a current wait-time widget and an hourly planner widget for the same checkpoint groups.
- Terminal 1 and Terminal 3 have distinct checkpoint groupings on the official wait-time page.

LAS terminal and airline notes
- Terminal 1 and Terminal 3 have distinct checkpoint groupings on the official wait-time page.
- Use the live widget labels rather than assuming the terminal with the shortest name is always the fastest checkpoint entry.
- Southwest-heavy traffic often routes through Terminal 1, while many other carriers use Terminal 3.
