Top 7 Airport Security Mistakes You Should Avoid

Fact checked by Elizabeth MacLennan

We’ve all been there – stuck behind the slow-moving traveler in the airport security line. The frazzled, overpacked individual appears woefully unprepared for the task at hand. Or, perhaps you’ve been that person – lost, confused, and feeling the impatience of those behind you.

Unless you fly private, passing through security is an unavoidable component of air travel. It can be mundane at best and chaotic and stressful at worst; however, it doesn’t have to be that way.

Below, find a list of mistakes to avoid to make your airport security experience as smooth as possible.

1. Arriving Unprepared

You won’t get far if you don’t have the essential documents needed to board your flight. In fact, you won’t even be able to pass through security without your boarding pass and/or proper identification.

Ensure that you have these items on hand (if you’re traveling internationally, you’ll also need your passport) and keep them accessible, not buried at the bottom of your suitcase.

“The main thing is to bring the required travel documents, which you should research in advance of your trip,” says Sophie Hocquez, commercial director of low-cost, long-haul airline French Bee. “What’s required to travel to this destination? Consult your destination’s official website (take France, for example), as it will list all travel documents required.”

If you’re flying overseas, also check the expiration date on your passport and your destination’s validity requirements; some countries require you to travel with a passport that does not expire for at least six months.

2. Forgetting to Give Yourself Plenty of Time

Jessica Mayle, public affairs specialist for TSA’s Great Lakes Region, recommends arriving with plenty of time to avoid hurrying through the airport.

“Many airports are seeing activity levels that nearly match or exceed pre-pandemic customer screening numbers,” Mayle states. “Additionally, some airports are experiencing new airlines or a heightened number of flights from legacy airlines. All of this means more passengers going through screening. This is why it’s essential to arrive early and ready to complete every step of the travel process from curb to gate.”

There’s nothing worse than trying to maneuver to the front of the security line due to unexpected delays caused by a longer wait. Instead, arrive earlier than you think you need to (at least two hours before your domestic flight, and three if traveling internationally) and avoid the frantic rush.

3. Not Investing in TSA PreCheck

If you travel more than once or twice a year, TSA PreCheck is definitely worth the investment. Additionally, applying for Global Entry includes TSA PreCheck in the program. Curious about the time savings? In August 2021, 96% of TSA PreCheck travelers waited five minutes or less during screening, according to Mayle.

“People can ‘Travel With Ease’ and experience a smoother screening process by enrolling in TSA PreCheck,” Mayle advises. “Eligible travelers do not need to remove shoes, belts, light outerwear, laptops, electronics larger than a cell phone, or travel-size liquids from their carry-on luggage.”

Moreover, another advantage of the program is that children aged 12 and under can use the TSA PreCheck lane when accompanied by an eligible parent or guardian traveling on the same itinerary.

4. Not Packing Strategically

One of the worst mistakes you can make when going through security is stowing items that you’ll need in a place that’s not easily accessible. Keep your ID, passport, and phone in your pocket or an outer compartment of your bag so you can quickly grab them when needed. Additionally, pack your liquids in a single, easy-to-remove bag.

“Put all travel documents in one small pouch and keep that on you at all times,” Hocquez recommends. “Then, you’ll avoid having to search among your belongings for documents when security requests them, which can happen several times.”

“Keep in mind that you’ll have to remove some items when going through security, so have luggage that allows for easy packing and unpacking of your computer, phone, tablet, and other devices,” Hocquez adds. “Verify your toiletries’ volume to ensure compliance with regulations, and pre-pack them together in a Ziploc bag that is easily accessible in your carry-on.”

Moreover, check the regulations regarding what’s allowed in your carry-on versus checked luggage.

5. Dressing Uncomfortably

If you don’t have TSA PreCheck, be prepared to remove your outerwear, shoes, and belt during the security screening. Moreover, even with TSA PreCheck, remember that if you are traveling internationally, you will still go through the standard security check upon returning home.

“Wear shoes that are easy to take off, especially if you’re traveling with children,” Hocquez suggests. “Avoid strappy sandals and laces whenever possible.”

6. Packing Prohibited Items

This might appear to be a straightforward guideline, yet many travelers pack prohibited items in their luggage, often unknowingly. This not only delays the screening process for everyone but could cause serious complications.

“We’re observing a significant number of prohibited items appearing in carry-on bags, which extends the lines,” Mayle reports. “If a carry-on bag sets off an alarm, it necessitates a TSA officer to inspect the bag personally. Remember, minimizing touchpoints is crucial during a pandemic, so ensure you’re not packing any prohibited items.”

Only bring items you know are allowed in your carry-on luggage and pack appropriately to avoid undue hassle.

7. Not Interacting With the TSA Before Departing

Do you need to find out if a specific item is permitted in your carry-on or checked baggage? Mayle notes that the TSA website features a section called “What can I bring?” Here, users can enter the name of an item, and the site will indicate if it should be packed in a checked or carry-on bag, or if it’s entirely forbidden.

“The same useful feature is also available on the free, downloadable MyTSA app,” Mayle remarks. “The app grants users 24/7 access to frequently requested airport security information on any mobile device.”

Mayle adds that the TSA has an active social media presence. “Travelers can send inquiries about where an item should be packed via Twitter to @AskTSA or through Facebook Messenger for immediate assistance.” This service is available from 8 a.m. to 6 p.m. ET every day, including holidays.
