10 Mistakes That Slow You Down at TSA (and How to Avoid Them)

Airport security can be one of the most stressful parts of flying. Long lines, strict rules, and the rush to get through screening often cause travelers to make mistakes that delay them and even risk losing important belongings. By preparing ahead and knowing what to expect, you can move through security faster and with less stress.

Here are the most common airport security mistakes — and the smarter alternatives.

1. Putting valuables directly in bins

Keys, wallets, IDs, boarding passes, and phones are small and easy to misplace when tossed loosely into bins. With so many items moving down the conveyor belt at once, they can be forgotten, lost, or even picked up by someone else by mistake.

Better option: Keep valuables in a zippered pocket of your carry-on or personal bag. That way, your essentials stay secure, and you’ll know exactly where they are when you need them.

2. Leaving bags unattended

Security areas are busy, and unattended luggage attracts attention — sometimes even leading to delays while officials investigate. Beyond that, you risk theft or mix-ups if you aren’t watching your belongings.

Better option: Always keep your eyes on your bags. Attach sturdy luggage tags with your contact info and consider a Bluetooth tracker so you can locate your bag quickly if it gets separated.

3. Removing jewelry unnecessarily

Many travelers think they must remove all jewelry, which leads to fumbling with rings and bracelets in the line. In most cases, small items like rings, earrings, and simple necklaces don’t trigger alarms.

Better option: Leave small jewelry on. If you’re wearing larger, bulky pieces that might set off the scanner, store them neatly in a travel jewelry organizer inside your bag before you get in line.

4. Packing prohibited sharp items

Sharp items like knives, scissors over 4 inches, or box cutters will be confiscated if found in carry-on bags. Losing them not only wastes money but can delay your screening if your bag requires extra inspection.

Better option: Double-check TSA’s prohibited items list before you pack. If you want a practical tool, stick to TSA-approved multitools that meet carry-on regulations.

5. Bringing drinks through security

Security rules limit liquids to 3.4 ounces (100 milliliters) per container, all stored in a single quart-sized bag. Larger bottles or open drinks will be discarded at the checkpoint.

Better option: Bring an empty reusable water bottle. Once you’re past security, you can fill it at water fountains or refill stations to stay hydrated without overpaying for bottled water.

6. Overpacking toiletries

Many travelers pack full-sized shampoo, lotion, or sprays, only to have them thrown out during screening. Not only is it wasteful, but it also takes up valuable bag space.

Better option: Follow the TSA 3-1-1 liquids rule (3.4 oz bottles, 1 quart-sized bag, 1 per passenger). Use travel-sized products or refillable silicone bottles to stay compliant and organized.

7. Wearing shoes that take too long to remove

Laced boots, strappy sandals, or complicated sneakers can slow you down when security requires shoe removal. The longer it takes, the more stressful the line becomes.

Better option: Wear slip-on shoes or sneakers that are easy to take on and off. This is especially useful for families traveling with kids. If you have TSA PreCheck, you can usually keep shoes on.

8. Using non-TSA approved locks

If your luggage is secured with a standard lock, TSA officers may have to cut it off during inspections. That leaves your bag unlocked for the rest of your trip.

Better option: Use a TSA-approved lock that officers can open with a master key. These are widely available, inexpensive, and help protect your belongings without risk of damage.

9. Forgetting to remove laptops

At many airports, laptops and tablets must be removed from carry-on bags and placed in a separate bin. Travelers who forget often cause delays when screeners need to rescan their bags.

Better option: Keep your laptop in an easy-access sleeve inside your carry-on. That way, you can slide it in and out quickly without disrupting the line. Some TSA-friendly laptop bags even unzip flat for screening.

10. Wearing bulky jackets or too many layers

Heavy coats, layered clothing, or oversized jackets usually need to be removed at security. Struggling with multiple layers slows the process and can make you uncomfortable.

Better option: Dress in comfortable, layered clothing that’s easy to manage. A light jacket or sweater that you can slip off easily is best. If you have TSA PreCheck, you’ll often be able to keep your jacket on.
