What to Never Put in Your Checked Bag

Quick answer: Keep your medications, travel documents, valuables and electronics, and one full change of clothes in your carry-on rather than your checked bag. A checked bag can be delayed or lost, and none of those items are ones you want to be without while you wait for it to turn up. Here's the full list, and why each item earns its spot.

The dinner outfits are packed. The sunscreen made the cut. You've downloaded enough books to survive a fourteen-hour flight delay. It's the far less exciting items, the ones you barely notice until the exact moment you need them, that tend to get left out of the suitcase entirely. Here's what I always tell clients to add to the list before their next trip.

A Physical Form of Payment

Apple Pay and Google Pay are wonderful, right up until a card reader or a country doesn't cooperate with either one. Bring at least one physical credit card, ideally a backup card too, and a small amount of local cash for your destination. If a rental car is part of the trip, double-check ahead of time which physical card needs to be presented at pickup.

Your Insurance Information

Nobody plans on needing medical care while traveling, which is exactly why this one gets forgotten so often. Save or print your travel insurance details along with your regular health insurance information, and know ahead of time who to contact and how if you ever need to use that coverage.

Backups of the Important Documents

A passport matters. A backup copy of that passport matters even more the moment the original goes missing. Keep copies of your passport, visa or entry documents, itinerary, confirmations, addresses, and important phone numbers somewhere secure that doesn't depend on your phone or wallet being with you. Technology is fantastic until it decides to fail you in an unfamiliar country.

More Medication Than You Think You Need

If you take prescription medication, resist the urge to pack the exact number of pills for the exact number of days. Flights get delayed, trips get extended, and a little extra buffer goes a long way. Bring more than you need, keep essential medication in your carry-on rather than a checked bag, and check destination-specific rules ahead of any international travel.

A Backup Way to Power Your Phone

Boarding passes, maps, translation apps, hotel confirmations, and the ability to reach your travel advisor when something goes sideways all live on that one device. A portable charger has a way of going from a nice extra to the most important item in your bag by day two of a trip.

A Photo of Your Checked Luggage

Before handing your suitcase over and watching it vanish down the conveyor belt, take a quick photo of the bag itself and what's inside it. If it's delayed or lost, that photo gives you something to point to when describing it and a record of what was packed if you ever need to file a claim.

The Bottom Line

None of these items take up much room, and every one of them is far easier to pack ahead of time than to replace mid-trip. A little extra thought before you zip that bag closed can save an entire afternoon of your vacation later.

Destination-specific packing details, the kind that vary by climate, culture, or activity, are something I'm always happy to include alongside your custom itinerary. When it's time to pack your bags, you know where to find me.

A few questions I get asked about this

What should always go in a carry-on instead of a checked bag? Medications, travel documents (or copies of them), valuables and electronics, and at least one change of clothes. These are the items that cause the most stress if a checked bag is delayed, so keeping them within arm's reach removes that risk entirely.

Is it really necessary to carry paper backups of documents if everything is on my phone? Yes, especially for international travel. A phone can lose battery, get lost, or stop working at the worst possible moment. A paper or offline copy of your passport, itinerary, and confirmations means you're never fully dependent on your phone functioning.

How much extra medication should I actually pack? More than the exact number of days you'll be traveling. Delays and extended trips happen, and running out of a prescription somewhere unfamiliar is a much harder problem to solve than packing a few extra doses.

What's the point of photographing checked luggage before it's handed over? It gives you a clear reference for describing the bag if it's delayed or lost, and a visual record of what was inside if you need to file a claim with the airline.
