These items could get you flagged—experts warn travelers about this packing mistake

Traveling is one of life’s great joys—especially when you’ve earned the right to take it easy and explore the world on your own terms.

But as any seasoned traveler will tell you, a dream vacation can quickly turn into a logistical nightmare if your checked luggage goes missing, gets damaged, or is rifled through by the wrong hands.

Here at The GrayVine, we know that a little preparation goes a long way, and we’re here to help you avoid the most common—and costly—packing mistakes.

Recently, travel experts have sounded the alarm about a handful of items that should never be stowed in your checked luggage. While these may seem like no-brainers, you’d be surprised how many travelers (even the most experienced among us!) make these errors, only to regret it when their suitcase takes a detour.



Let’s break down the must-know advice, add some real-world context, and share a few extra tips to keep your next adventure smooth, safe, and stress-free.

1. Prescription Medications: Your Health Should Always Be Within Reach​

It’s tempting to toss your pill organizer into your checked bag and forget about it until you reach your destination. But what happens if your luggage is delayed, lost, or—heaven forbid—stolen?

Replacing prescription medications abroad can be a Herculean task, especially if you’re in a country with different pharmacy regulations, language barriers, or limited access to healthcare. Even at home, getting a refill without your doctor’s direct approval can be tricky, and some prescriptions don’t allow for early refills at all.

If you rely on daily medication, always keep it in your carry-on, along with a copy of your prescription and your doctor’s contact information. And if you use medical devices (like insulin pens, inhalers, or EpiPens), those should stay with you, too.

2. Electronics: Keep Your Gadgets Close and Safe​



Laptops, tablets, e-readers, cameras, and smartphones are not only expensive—they’re also magnets for sticky fingers. Checked luggage passes through many hands and conveyor belts, and while most airport staff are honest, theft does happen.

Even if your electronics aren’t stolen, they can be damaged by rough handling or extreme temperatures in the cargo hold.

Airlines also recommend keeping lithium batteries and power banks in your carry-on, as they can pose a fire risk in the cargo hold. So, if you can’t live without your Kindle or you’re planning to snap photos of every sunset, keep your devices with you.

3. Valuables: If It’s Priceless, Don’t Check It​

Jewelry, watches, cash, important documents, and family heirlooms should never be out of your sight. Not only are these items irreplaceable, but airlines typically limit their liability for lost or damaged valuables in checked bags.

If you must travel with something precious, carry it on your person or in your carry-on bag.

Pro tip: Make digital copies of your passport, travel insurance, and other critical documents, and store them securely online or on a USB drive in your carry-on.



4. Daily Necessities: Be Ready for Anything​

Imagine arriving at your destination, only to discover your suitcase is on a solo adventure. Now you’re stuck in yesterday’s clothes, without your toothbrush, glasses, or a fresh pair of socks.

Always pack a change of clothes, essential toiletries (in TSA-approved sizes), and any must-have items (like reading glasses or hearing aids) in your carry-on. If you wear contacts, bring your case and solution, too.

A lightweight sweater or scarf can be a lifesaver if the plane gets chilly or you’re caught in unexpected weather. And don’t forget snacks—airport food is expensive, and delays are all too common.

5. Hard-to-Replace Items: Don’t Gamble with the Irreplaceable​

Maybe it’s your favorite book, a custom medical device, or a unique travel adapter. If you know it’ll be tough to replace at your destination, keep it with you.

Even for short trips, it’s better to be safe than sorry. This is especially true for items that are specific to your needs or comfort—think orthopedic insoles, specialty chargers, or that one brand of tea you can’t live without.

Bonus Tips for Savvy Travelers​

- Label Everything: Put your name and contact info inside and outside your bags. If your luggage is lost, this makes it easier to reunite you with your belongings.
- Use TSA-Approved Locks: They won’t stop a determined thief, but they can deter casual snooping.
- Consider Travel Insurance: Some policies cover lost or delayed luggage, so you can replace essentials without breaking the bank.
- Pack Smart: Make a checklist before you travel, and double-check it as you pack. It’s easy to forget the little things in the excitement of a trip.

Key Takeaways

  • Travellers are advised not to pack prescription drugs in their checked luggage, as retrieving replacements can be difficult if your bag is lost or stolen, especially overseas or during holidays.
  • Valuable electronics and personal items should be kept in your carry-on to avoid the risk of theft or damage, since checked bags can be accessed by multiple people and handled roughly.
  • Daily necessities such as a spare change of clothes, toiletries, glasses, and other essentials are better kept with you, as they may be urgently needed if your checked luggage is delayed or missing.
  • Items that are hard to replace or find at your destination should always be taken in carry-on baggage to avoid the hassle and stress of trying to source them while travelling.
