Most people treat airport security like a lottery – show up, hope for the best, and pray the line moves. But experienced travelers know the checkpoint is almost entirely predictable. The rules haven’t changed as dramatically as people think, but the strategies that actually cut your wait time in half are hiding in plain sight. TSA processed over 900 million passengers in 2024 alone, and the difference between the person who breezes through in four minutes and the one holding up the line for ten is almost always a handful of avoidable mistakes.
Here’s the thing nobody tells you upfront: most checkpoint slowdowns aren’t caused by security – they’re caused by the traveler in front of you who packed wrong, dressed wrong, or signed up for the wrong program. Get these 15 things right, and the whole experience flips from stressful to almost boring. Here’s what TSA insiders and frequent flyers actually do differently.
#15 – Your Shoes Don’t Have to Come Off Anymore
One of the longest-running frustrations in airport security history quietly ended in 2025. On July 8, 2025, DHS Secretary Kristi Noem announced that passengers no longer need to remove their shoes during security screening, ending a practice that had been in place since 2006 after a failed terrorist attempt to detonate explosives hidden in shoes. That’s nearly two decades of sock-footed shuffling across grimy airport floors – over.
That said, your screening will still go faster if you proactively take off shoes with metal, like Birkenstocks, which will likely set off the detectors even though the shoes-off policy has been reversed. So keep your sneakers on, but if you packed the rhinestone sandals, expect a delay. Dress smart and this one costs you zero extra seconds at the checkpoint. But that’s nothing compared to what we found about #14…
#14 – Sequins and Rhinestones Are a TSA Nightmare
Nobody talks about this one, and it catches people off guard every single time. Sequined tops or blouses typically alarm the scanning machine and require additional pat-downs, and jeans with rhinestones on the back pockets generally do too. Metal bracelets may be fashionable, but they set off the metal detectors. A seasoned TSA officer will tell you straight: save the glam for your destination.
The practical fix is simple. Wear clothing without metal and be ready to remove your belt if it has a metal buckle. Tuck large metal jewelry into your carry-on bag before you go through the security checkpoint. If you have body piercings, either remove them before going through security or prepare yourself for a pat-down screening. **The single fastest outfit choice you can make is slip-on shoes, no belt, and zero metal accessories.** But that’s nothing compared to what we found about #13…
#13 – The myTSA App Has a “Can I Bring This?” Tool Almost Nobody Uses
Every year, TSA confiscates thousands of items that travelers could have simply packed differently if they’d just checked ahead of time. The free myTSA app includes a handy “What Can I Bring?” tool – travelers can type in an item to find out if it’s permitted. You can also ask questions on Twitter or Facebook Messenger at @AskTSA, or by texting “Travel” to AskTSA (275-872). That’s a live human response before you even leave home.
You can always send a picture or question to AskTSA on Facebook Messenger or X, and agents are available to respond during normal business hours to help you before your trip. **Most people google their weird items and get outdated answers – the app pulls directly from TSA’s current database.** This two-minute check at home eliminates the most common cause of bag searches at the checkpoint. But that’s nothing compared to what we found about #12…
#12 – Powders Are the New Liquids (and Most Travelers Don’t Know It)
The 3-1-1 liquids rule is famous, but powders are quietly causing just as many slowdowns – and almost nobody prepares for this. TSA officers may instruct travelers to separate items from carry-on bags such as foods, powders, and any materials that can clutter bags and obstruct clear images on the X-ray machine. Protein powder, dry shampoo, baby powder, makeup setting powder – all of it can flag.
Powdered items such as coffee, spices, and baby powder in excess of 12 ounces will be subject to additional screening. Based on TSA guidance, powders may need additional screening, and it’s worth considering putting powders into your checked bags unless they are medically necessary. **Quantities over 12 ounces almost guarantee a hand-search of your entire bag.** Keep powder containers small and labeled, or check them altogether. But that’s nothing compared to what we found about #11…

#11 – Peanut Butter Is a Liquid (and So Is Your Hummus)
This sounds absurd, but it costs people their snacks every single day. TSA gets a lot of people who try to bring peanut butter through – and unfortunately, because it can smear, it falls under the 3-1-1 rule. Your protein bars and solid snacks are fine, though. The general principle is that anything that can spread, pour, or squish is treated as a liquid at the checkpoint.
The latest guidance is that travelers can bring solid snack foods such as pretzels, potato chips, sandwiches, or carrot sticks – but spreadable items like peanut butter or hummus are subject to the 3-1-1 rule. Solid items can go through a checkpoint, but passengers carrying items that can spill, spread, spray, pump, or pour and are larger than 3.4 ounces should pack those in checked luggage. **A single jar of almond butter can trigger a full bag search that adds 10 minutes to your wait.** But that’s nothing compared to what we found about #10…
#10 – Packing Your Bag Cluttered Is the Real Hidden Enemy
You can follow every rule perfectly and still get your bag pulled for secondary screening – if it looks like a junk drawer on the X-ray monitor. TSA recommends keeping your bag organized to help ease the screening process, because it takes time for officers to make sure a jam-packed, cluttered, overstuffed bag is safe. The X-ray operator literally cannot clear what they cannot see clearly.
Keep your quart-sized liquids bag and electronics in an easy-to-reach spot for fast removal. Store small items like chargers, medication, or snacks in see-through pouches to avoid digging through your bag at the checkpoint. Avoid overpacking, since TSA officers may need to inspect crowded bags more closely, which can slow you down. **A clear, organized bag moves through X-ray in seconds. A stuffed, messy one can trigger a hand inspection that takes minutes.** But that’s nothing compared to what we found about #9…
#9 – CT Scanner Lanes Mean You Can Leave Your Laptop in Your Bag
Here’s a genuine insider advantage that most travelers walk right past. CT is the latest checkpoint X-ray scanning equipment to enhance threat detection capabilities for carry-on baggage – the technology is similar to CT technology used in the medical field, and research shows CT is the most consequential technology available at airport checkpoints today. At lanes equipped with these scanners, the old “laptop out of the bag” rule no longer applies.
At standard X-ray lanes, you’ll remove laptops and larger electronics. But in CT scanner lanes, you can typically leave them in your bag. CT scanners provide detailed 3D images of bag contents, allowing laptops, electronics, and liquids (3.4 ounces or less) to remain inside carry-ons. **Look for the CT scanner sign before you load your bins – it could save you two full minutes of unpacking and repacking.** But that’s nothing compared to what we found about #8…
#8 – Automated Screening Lanes Move Significantly Faster Than Standard Lanes
Not all security lanes are created equal, and most travelers have no idea there’s a difference. Automated Screening Lanes are a state-of-the-art checkpoint technology that enhances security efficiency while decreasing the amount of time travelers spend during the security screening process. These lanes have wider bins, automated conveyor returns, and RFID bin tracking that keep the line flowing without the bottlenecks of traditional checkpoints.
