Key Takeaways
Why Security Lines Stall More Than They Should
The frustrating truth about airport security delays is that most of them are entirely preventable. TSA officers routinely flag the same categories of items and behaviors day after day — not because travelers are careless, but because the rules are easy to forget when you're already juggling a packed schedule. A few simple adjustments before you arrive at the checkpoint can mean the difference between a smooth walkthrough and a 20-minute standstill.
If you're building a trip where timing matters — and it usually does — pairing good security habits with a well-structured plan pays off. Our guide to building a solid travel itinerary covers how to build time buffers so one delay doesn't cascade through your whole trip.
Forgetting the liquids rule — again.
Why it happens: The 3-1-1 rule (containers of 3.4 oz or less, all in one quart-sized clear bag) is well-known but easy to violate when you grab toiletries in a rush or borrow items from home that exceed the limit.
Wearing the wrong outfit through security.
Why it happens: People often dress for the destination or comfort rather than for the checkpoint, arriving in heavy boots, a belt with a large buckle, a jacket with metal buttons, or multiple layers.
Leaving a laptop or tablet buried inside a packed bag.
Why it happens: Unless you have TSA PreCheck, laptops must come out of their sleeve and go in a separate bin — but many travelers pack them deep in a bag that takes a minute to unzip and dig through.
Carrying undeclared food items that read as dense on the X-ray.
Why it happens: Solid food is generally allowed through security, but dense items — a jar of peanut butter, a block of cheese, a wrapped sandwich — can look suspicious on screen and trigger a bag pull.
Not having your ID and boarding pass ready.
Why it happens: Travelers frequently reach the document check and then spend 30 seconds digging through a purse, pockets, or phone apps to find what they need.
Overpacking carry-on bags to the point of X-ray opacity.
Why it happens: Fitting as much as possible into a carry-on is a common travel goal, but a densely packed bag produces a cluttered X-ray image that's harder for officers to clear quickly.
Practical Habits That Move You Through Faster
Beyond avoiding the mistakes above, experienced travelers develop a consistent pre-security ritual. Before your trip even begins, think through what's in your bag. Packing intentionally — rather than tossing things in at the last minute — makes the X-ray image cleaner and easier for officers to read, which directly reduces the chance of a bag pull. Our roundup of overlooked travel bag essentials highlights compact, TSA-friendly alternatives that seasoned travelers rely on.

TSA PreCheck-eligible travelers enrolled
According to TSA program data, tens of millions of travelers have enrolled in PreCheck, with dedicated lanes now available at hundreds of U.S. airports.
~5 min
Average PreCheck lane wait time
TSA reports that the vast majority of PreCheck passengers wait under five minutes, compared to substantially longer waits in standard lanes during peak periods.
If you fly more than a few times a year, enrolling in TSA PreCheck is one of the most consistently useful travel investments you can make. The program lets approved travelers use dedicated lanes where shoes, laptops, and liquids can stay in your bag. Global Entry includes PreCheck and also streamlines re-entry for international trips — pairing well with the prep covered in our pre-arrival international travel checklist.
Enrollment Takes Time — Plan Ahead
TSA PreCheck enrollment requires an in-person appointment at an enrollment center, and processing can take several weeks. If you're planning a trip soon, apply well in advance rather than assuming you'll be approved in time. Check the official TSA website for current wait estimates and enrollment locations near you.
At the checkpoint itself, treat every bin like a reset: shoes, belt, jacket, and any loose metal all go in separately or on top of your bag — never crammed inside it. Hold your ID and boarding pass in your hand until you've cleared. The travelers who move fastest are almost always the ones who've done this enough times that it's a habit, not a scramble.
