The fastest way to get through airport security is to do the work before you reach the checkpoint: pack liquids and electronics where you can reach them, wear easy-to-remove clothing, arrive at a sensible time for your airport and have your ID and boarding pass ready. None of this is complicated, but together it can turn a stressful shuffle into a smooth couple of minutes.

Pack so your bag is easy to screen

Most delays at the belt come from a bag that has to be pulled aside and opened. A little organization at home prevents that.

• Liquids: carry-on liquids, gels and aerosols generally need to be in containers of 3.4 ounces (100 ml) or less, all fitting together in one clear quart-size bag. Put that bag at the top of your carry-on, or in an outside pocket, so you can lift it out in one motion.
• Bigger bottles: if a product is larger than the limit, put it in your checked bag, or buy a drink after you pass security. Empty your water bottle before the checkpoint and refill it at a fountain on the other side.
• Electronics: laptops and larger electronics usually need to come out of the bag and sit in their own bin. Keep your laptop in a front compartment, or use a sleeve that lets you slide it out quickly. Rules for smaller devices can vary, so follow the signs and officer instructions on the day.
• Chargers and cables: a tangle of cords can look confusing on a scanner. Bundle them in one pouch.
• Do not overstuff: a crowded bag is harder to read on the screen and more likely to be opened by hand. Leaving a little breathing room helps.

When in doubt about whether an item is allowed, check the TSA website before you pack. It lists what can go in a carry-on, a checked bag, or neither.

Dress for the checkpoint

What you wear changes how many things you have to put in a bin. A few small choices save real time.

• Slip-on shoes are easier than lace-up boots when you may be asked to remove footwear.
• Skip the heavy accessories: big belts, chunky jewelry and watches can trigger extra screening. Put them in your bag before you get in line, or wear them only after the checkpoint.
• Layers over bulk: a jacket or heavy sweater often has to come off and go through the scanner. Wear a light layer you can pull off quickly, and keep pockets empty.
• Empty your pockets early: keys, coins, phone and wallet can go into a coat pocket, then into your bag, so you only handle one item at the belt.

Get your documents ready

Have your ID and boarding pass in your hand, not buried in a bag, by the time you reach the officer at the front. If your boarding pass lives on your phone, turn up the screen brightness and make sure it is open to the right page. A phone that locks itself or runs out of battery in line is one of the easiest ways to hold up everyone behind you. A paper backup is cheap insurance on a long travel day.

Choose your timing wisely

A common rule of thumb is to arrive about two hours before a domestic flight and about three hours before an international one. That is a starting point, not a guarantee. Security lines depend heavily on the airport, the terminal, the day of the week and the hour.

• Early morning and late afternoon are often the busiest, when many flights leave close together.
• Holidays and long weekends push volumes up. Allow extra time.
• Big airports may have several checkpoints. A shorter line at a different one can be worth a short walk, if you can reach your gate from it.
• Checking a bag adds a bag-drop line before you even reach security, so build that into your plan.

It also helps to think backward from your boarding time, not your departure time. Gates close and boarding starts well before the plane leaves, so work out when you need to be at the gate and subtract the time for the walk, the screening line and the drive.

What PreCheck does, in general terms

TSA PreCheck is a government program that lets approved travelers use a separate lane at participating airports and airlines. In general, travelers in that lane can keep shoes, a light jacket and a belt on, and may leave laptops and a compliant liquids bag in their carry-on. The lines are often shorter, though not always, and eligibility depends on the airline and the airport. If you fly several times a year, it can be worth looking into. Check the official TSA site for current details, fees and how to apply, because they change over time.

Use the time you save

Getting through the line quickly is useful only if you are not rushing afterward. Once you are through, repack calmly at a bench instead of at the belt, put your shoes back on, and head to your gate. Refill your water bottle, grab a snack and use the extra minutes to relax. Walking to the gate is much more pleasant when you are not sprinting.

Know the line before you leave

The biggest unknown is usually how long the line will actually be. Our free TSA Wait Times mobile app shows live checkpoint data where airports publish it and predicted waits for the rest, so you can decide when to leave home. Please note it is an independent app and is not affiliated with the Transportation Security Administration, the Department of Homeland Security or any airport. Predictions are estimates, so always allow a cushion on busy days.

Frequently asked questions

How early should I get to the airport?

Many travelers aim for about two hours before a domestic flight and three before an international one. Allow more for holidays, large airports, checked bags or if you are traveling with children or extra gear. Allow a bit less only if you are certain your airport is quiet.

Do I have to take my laptop out of my bag?

Usually yes, at standard lanes, laptops and larger electronics go in their own bin. Some lanes and programs have different rules, so follow the posted signs and the officers' instructions.

Can I bring an empty water bottle through security?

Yes. An empty reusable bottle is generally fine. Fill it at a water fountain or refill station after the checkpoint.

Is PreCheck always faster?

Often, but not always. Lines vary by airport and time of day. It tends to save the most effort on busy days because you handle fewer items at the belt.
