What to expect at the TSA checkpoint

TSA security takes 15 to 45 minutes depending on the time of day, airport size, and how prepared you are. You will remove shoes, belt, and jacket; take out your laptop and liquids bag; and walk through a metal detector or body scanner. TSA officers are looking for prohibited items and threats, not trying to slow you down. The faster you move through each step, the faster everyone moves.

Arrive at the airport at least two hours before a domestic flight, or three hours before an international flight. This gives you time to find your terminal, stand in line, and move through security without rushing. If you rush, you make mistakes—forgetting to remove your laptop, leaving liquids in your carry-on, or wearing shoes that take forever to unlace—and those mistakes add 10 minutes to your time.

Key Takeaways

  • Wear slip-on shoes, minimal jewelry, and a belt you can remove quickly so you spend less time undressing at the checkpoint.
  • Pack your carry-on with your laptop and liquids bag on top so you can pull them out without digging through everything else.
  • Have your ID and boarding pass ready in your hand before you reach the officer, not in your pocket or bag.
  • TSA PreCheck costs $78 to $85 for five years and lets you keep shoes, belt, and light jacket on, and leave your laptop and liquids in your bag.
  • The TSA website shows wait times for your specific airport and terminal, updated every few minutes.

Prepare your documents and ID before you arrive

Have your government-issued ID and boarding pass in your hand or an straightforward-to-reach pocket before you get to the front of the line. The officer will ask for both. If you fumble through your bag or wallet while the line backs up behind you, you slow down the whole checkpoint. A passport, driver's license, or state ID all work for domestic flights. For international flights, you need a valid passport.

Your boarding pass can be printed or on your phone—either works. If it is on your phone, have it open and ready to show. Do not make the officer wait while you unlock your phone, find your airline app, and navigate to your reservation.

Pack your carry-on so you can remove items quickly

Put your laptop and liquids bag on top of everything else in your carry-on. When you reach the security bin, you will pull them out first and place them in the bin without unpacking your whole bag. This takes 20 seconds instead of two minutes.

Your liquids bag must be one quart-sized clear plastic bag holding containers of 3.4 ounces (100 milliliters) or smaller. Include shampoo, conditioner, lotion, toothpaste, deodorant, and any liquid or gel. Solid deodorant, solid lotion bars, and lipstick do not need to go in the bag. If you are unsure whether something counts as a liquid, pack it in the bag—it is faster than explaining it to an officer.

Wear slip-on shoes, not lace-up boots. Wear a belt you can unbuckle in two seconds. Wear minimal jewelry—remove rings, bracelets, and necklaces before you leave home if you can, or put them in your carry-on to put back on after security. Every second you spend unlacing shoes or removing jewelry is a second the line waits.

Move through the checkpoint step by step

When it is your turn, step up to the officer with your ID and boarding pass ready. The officer will scan your ID and boarding pass and wave you forward. Walk to the bins and place your carry-on on the belt. Remove your shoes and place them in a bin. Remove your belt and place it in a bin. Remove your jacket or sweater and place it in a bin. Remove your liquids bag and laptop and place them in separate bins.

Place your carry-on on the belt after your bins so it goes through the scanner. Walk through the metal detector or body scanner when the officer tells you to. If you set off the metal detector, you will be pulled aside for a pat-down or a second scan. This is normal and happens to many people—do not panic or resist. Stand still, let the officer do their job, and you will be on your way in under a minute.

On the other side of the scanner, collect your bins and carry-on in the order they come out. Put your shoes back on, your belt back on, and your jacket back on while you are still at the end of the conveyor belt, not while you are walking and blocking other people. Put your laptop and liquids back in your carry-on. Move away from the checkpoint area.

Consider TSA PreCheck if you fly more than once a year

TSA PreCheck costs $78 to $85 for a five-year membership and lets you go through a faster security line. With PreCheck, you keep your shoes, belt, and light jacket on. You leave your laptop and liquids bag in your carry-on instead of removing them. You do not have to remove your belt or empty your pockets of keys and coins. The PreCheck line is usually much shorter than the standard line, especially at busy airports and during peak travel times.

You explore online at the TSA website, pay the fee, and schedule an in-person appointment at a PreCheck enrollment center. The appointment takes about 10 minutes—they take your fingerprints and verify your identity. You get a Known Traveler Number (KTN) that you add to your airline reservations. When you check in, your boarding pass will show a TSA PreCheck indicator, and you will be routed to the PreCheck line.

PreCheck is worth it if you fly two or more times per year. If you fly once a year or less, the cost does not pay for itself in time saved.

Check wait times and choose your checkpoint wisely

The TSA website shows real-time wait times for most major airports. Go to tsa.gov, enter your airport code, and you will see the current wait time for standard security and PreCheck. Wait times update every few minutes. If one checkpoint shows a 45-minute wait and another shows 15 minutes, walk to the shorter line.

Large airports often have multiple security checkpoints in different terminals or different areas of the same terminal. Ask an airport employee which checkpoint is closest to your gate, or check the airport's own website or app—many airports show which checkpoints are open and their current wait times.

Arrive early enough that even a 45-minute wait will not make you miss your flight. Do not count on the shortest wait time you see online—peak travel times (early morning, late afternoon, holidays, and Sundays) can double the wait in minutes.

Know what you cannot bring through security

You cannot bring weapons, explosives, or sharp objects in your carry-on. This includes pocket knives, box cutters, scissors with blades longer than four inches, and most tools. You can pack these in your checked baggage if your airline allows it, but not in your carry-on.

You cannot bring more than 3.4 ounces of any liquid or gel in your carry-on, and all liquids must fit in one quart-sized clear bag. You cannot bring lighters, fireworks, or flammable items. You can bring a lighter in your checked bag if your airline allows it, but not in your carry-on.

You can bring food, books, electronics, and most everyday items. If you are unsure whether something is allowed, check the TSA website's "What Can I Bring?" tool—type in the item and it will tell you whether it is allowed in your carry-on, checked bag, or both.

Frequently Asked Questions

Do I have to remove my phone and keys at security?

No, but if you have metal keys or a metal phone case, they may set off the metal detector. To save time, empty your pockets into your carry-on or a bin before you walk through the detector. If you forget and set off the alarm, the officer will ask you to step back and remove the item, then walk through again.

What if I forgot my ID at home?

You can still go through security, but the officer will ask you additional questions to verify your identity. This takes longer and may delay you. Have a backup form of ID if possible—a passport, military ID, or even a student ID can help. If you have nothing, tell the officer and they will decide whether to let you through.

Can I bring my own water bottle through security?

No, not if it is full. You can bring an empty water bottle and fill it at a water fountain or refill station after you pass through security. Many airports have free water refill stations near the gates.

Why do some people go through a different line than others?

TSA PreCheck members, military personnel with military ID, and some airline frequent flyer members go through expedited lines. If you do not have PreCheck or another expedited status, you go through the standard line. The standard line moves just fine if you are prepared.

What happens if the officer finds something prohibited in my bag?

The officer will remove the item and either throw it away or ask you to check it in your baggage if your airline allows it. You will not be arrested for an honest mistake. If you intentionally bring a prohibited item, that is a different matter, but TSA assumes mistakes are honest unless there is reason to think otherwise.
