• TSA PreCheck is an airport-security express lane that can save you time while traveling.
• The program has more members than ever — over 20 million passengers are enrolled.
• Travel expert Gilbert Ott said these etiquette tips can keep you from holding up the line.

Those of us who've had TSA PreCheck for a while have seen the express airport security line moving slower than it should. We've had our patience tested by first-time users fumbling for passports at the counter, removing their coats when it's their turn to be scanned, and waltzing on through with a belt on.

These days, you're more likely to encounter newbies in the fast-pass lane than ever.

The TSA reported in August 2024 that program enrollment reached a record 20 million travelers. And roughly 2 to 3 million flight passengers used the faster security line per day so far in 2025.

In the TSA PreCheck line, pre-screened travelers can go through security quickly without taking off their shoes or removing electronics or liquids from their carry-on bags. With more travelers than ever signing up for the program, you're likely to encounter more newbies in the express lane these days.

It costs about $80 to enroll for five years, but you can get the service essentially for free through credit cards such as Capital One Venture, Capital One Venture X, Chase Sapphire Reserve, Delta SkyMiles, and American Express.

Gilbert Ott, who says he flies more than 200,000 miles a year and has been blogging about flying for the past decade, told Business Insider that the express airport security lane makes his life easier. Ott's blog, called God Save the Points, covers everything from airline news and flight reviews to travel tips and money-saving hacks, such as how to best use credit-card points. 

"I spend too much time in airports. As much as I may love them, sometimes the less time I spend in them, the happier I am," Ott said. "So the quicker I can get through and just be on a plane, the better."

While the TSA PreCheck line is often full of frequent flyers, those new to the program, which requires a background check, may not be as savvy about security etiquette, especially during busy travel times like summer. Ott said this can cause the line to move more slowly, but he shared his best tips for TSA PreCheck travelers.

Pre-strip before you even get to the airport

Pre-stripping is removing everything you may need to take off at security, from big jackets to the contents of your pockets, before you get in line.

"When I go to the airport, I take my belt off before I get there. I have it in my backpack, knowing I'll put it on as soon as I get through PreCheck," Ott told BI. "So keep the jewels and the watch in your bag. Then, when you get to the other side of security where you're not holding people up, you can do the glamour."

Ott said this process will make people move through the line quicker. 

"My routine is somewhere along the lines of comfy jeans, a T-shirt or hoodie, and then a bomber jacket," he said. "Essentials like my phone and passport go in my bomber jacket pockets while I wait in the queue so that when I step up to the scanners, my jacket is off, pockets are empty, my bags go on the trays, and off we go."

Leave the flashy shoes in your bag

TSA PreCheck passengers aren't required to take off their shoes. But in Ott's experience, passengers who wear fancy loafers or shoes with buckles or studs often get stopped because they set off the scanner. 

"The main thing is metal, either as part of the shoe or in the boot or heel of the shoe," Ott said. "Ceramic and rubber are usually fine. Basically, sneakers tend to always work."

Be ready before it's your turn

When you first get in line, Ott recommends having your boarding pass and identification out before it's your turn to show them. That way, you won't spend time searching for these documents while others wait behind you. 

If everyone followed Ott's advice, he thinks we'd all get through security faster. 

"If you think of the 20 seconds it takes somebody to do this very basic thing, and you'd multiply that by 50,000 people going through an airport's screens a day, you could pretty much just walk through an airport without stopping," Ott told BI. "We can all have a better time."

• First-time flight upgraders should be aware of business- and first-class etiquette.
• A flight expert shared his top tips for blending in with passengers who often book premium cabins.
• He said not to ask whether everything is free in first class or expect too much in business class.

When you're flying first class, etiquette is key for blending in with the opulent crowd — especially if you've never been in a premium cabin before. The same goes for business class.

Travelers in first and business class may be spoiled with welcome gifts, multicourse meals, and private seats for lounging. While tickets aren't cheap, credit card and airline rewards programs have made the luxurious cabins accessible for people accumulating points and miles.

If you're upgrading a flight for the first time, Gilbert Ott, who flies an estimated 200,000 miles a year, has a few tips for those who want to blend in with the first- and business-class crowds and avoid annoying more seasoned premium passengers.

Don't ask whether everything is free in first class

"I think the etiquette is that first class is about indulgence," Ott told Business Insider.

Ott doesn't recommend asking flight attendants whether each bonus offering is free because everything is complimentary, from meals to sparkling wine.

And there's nothing wrong with "filling your boots" to make the most of the perks, he added.

Don't expect too much in business class

While first-class passengers often get personalized experiences and are greeted by name, business-class flyers shouldn't expect the same level of attention.

"Business class is about efficiency. It's a comfortable seat where you can sleep or work," Ott said.

Staff members serve dozens of people in business class, while first-class cabins typically seat fewer than 10 passengers, he added.

"There's a lot of work that goes into all those meals and drinks," Ott said. "So if you're looking for an over-the-top experience, then first class is where you can expect staff to make the flight awesome. And that's what you're paying for."

Don't hover over passengers in doored seats

If you've flown recently, you may have noticed that many business- and first-class cabins have added doors to each seat to give passengers more privacy.

Ott said you shouldn't infringe on another traveler's space to fetch items from overhead bins.

"Don't awkwardly hover over the person because the whole idea of doors is that people can't look in on you," Ott said. "So when you wake up and someone is looking over your space, it's odd."

Don't take up too much overhead-bin space

BI previously reported that premium-cabin passengers are often entitled to overhead-bin space, and according to Ott, the bins are usually not too crowded. But that doesn't mean you should bring extra bags and put them wherever you want, as Ott has seen many passengers do.

Instead, Ott suggests keeping your limited belongings in the space above your seat.
