1. Full-Size Toiletries (Just Stop)

I watched a woman throw away a $40 bottle of perfume at security last month. It was over 3.4 ounces. Don’t let this be you. The TSA liquids rule hasn’t changed: containers must be 3.4 ounces or less, fitting in one quart-size bag.

Buy travel-size bottles or get a set of silicone refillable containers for $8 on Amazon. I’ve used the same set for three years. Save your full-size products for when you arrive.

2. Giant Hard-Shell Suitcases as Carry-On

Airlines are cracking down on carry-on size in 2026. I’ve seen people forced to check bags they thought would fit overhead. Hard-shell suitcases are heavier and can’t squeeze into tight bins.

Switch to a soft-sided carry-on. It weighs less, fits more, and squishes into overhead bins that hard cases can’t. I paid $95 for mine and it’s been on 50+ flights.

3. Complicated Lace-Up Shoes

Wearing combat boots with 12 eyelets to the airport is self-inflicted torture. You’ll hold up the security line while everyone watches you lace and unlace.

Wear slip-on sneakers or loafers. You’ll get through security in 10 seconds. I wear my slip-on Vans every flight — they’re comfortable, cheap, and security-friendly.

4. Wrapped Gifts

TSA will unwrap any gift they want to inspect. I saw a man’s beautifully wrapped present get ripped open at a checkpoint in Atlanta. It was heartbreaking.

Ship wrapped gifts ahead, or use gift bags instead of wrapping paper. TSA can open a gift bag, inspect, and close it without destroying anything.

5. Heavy Books and Magazines

Books are heavy. Three paperbacks add 2 pounds to your bag and take up space you need for other things. I switched to a Kindle years ago and never looked back.

If you don’t want an e-reader, download books on your phone. The Libby app connects to your library card for free audiobooks and e-books. I saved $200 last year using it.

6. More Tech Than You Need

Laptops, tablets, drones, portable speakers, three charging cables, a power bank, and headphones. That’s what I pulled out of one guy’s bag at a security scan. He couldn’t close his bag afterward.

Bring what you’ll actually use. I travel with my phone, one charging cable, a small power bank, and wireless earbuds. That covers everything I need for a week-long trip.

7. Strong-Smelling Food

Please don’t bring tuna sandwiches, hard-boiled eggs, or curry onto a plane. I sat next to someone eating a tuna sandwich on a 4-hour flight. I can still smell it.

Pack neutral snacks: granola bars, nuts, crackers, or a plain sandwich. Airport food is overpriced, but bringing reasonable snacks is smarter than fumigating the cabin.

8. Expensive Jewelry

Wearing your best watch and five rings to the airport means removing them all at security. That’s time-consuming and risky. Things get left behind in those plastic bins constantly.

Wear simple jewelry when flying. Pack valuables in your carry-on bag, not on your body. I wear a $20 watch and my wedding band. Everything else stays home.

9. A Pillow From Home

I see people dragging full-size bed pillows through terminals. They’re bulky, they take up your personal item allowance, and you look silly carrying one.

Get an inflatable neck pillow. They cost $12, pack flat, and actually support your neck on the flight. I bought mine at an airport shop three years ago and it’s still going strong.

10. Unrealistic Layover Times

This isn’t something you pack, but it’s the biggest mistake I see. People book 45-minute layovers, then miss their connection when the first flight runs 20 minutes late.

Give yourself at least 90 minutes for domestic connections and 2.5 hours for international. I never book under 2 hours, even domestically. The stress isn’t worth saving 30 minutes.

For the best routes and airlines, check my low-cost airlines guide for the Caribbean and Mexico. The right airline makes a huge difference in connection quality.

What You SHOULD Bring Instead

Here’s my actual airport packing list after years of flying:

• Soft-sided carry-on with wheels
• One quart-size bag with travel toiletries
• Slip-on shoes and a light jacket
• Phone with downloaded entertainment
• One charging cable and small power bank
• Neutral snacks and an empty water bottle (fill after security)
• Wireless earbuds
• Neck pillow (inflatable)

That’s it. This list has gotten me through security in under 5 minutes every time.

Save Money Before You Even Pack

Before you book your next flight, grab free travel certificates. I use them to cover hotel stays and resort packages on every trip. They’ve saved me over $3,000 in two years.

Check out how to get free travel certificates and see what’s available for your next destination. I never book a trip without looking first.
