Checked luggage is often where we toss our bulky and heavier items.
But did you know that certain things are strictly prohibited in checked luggage? Trust me, you don’t want to risk having your belongings confiscated or worse, facing fines from airport security (like TSA).
So let’s dive into the things you should never pack in your checked luggage and some helpful tips on how to handle restricted items.

TSA Checked Luggage Rules: What You Need to Know
The Transportation Security Administration (TSA) plays a key role in keeping airports and passengers safe by inspecting all baggage that passes through U.S. airports, including both carry-on and checked luggage.
Their job is to ensure that passengers aren’t traveling with dangerous or prohibited items.
During their checks, they may encounter everything from toiletries to some rather unusual items.
If they find something on their restricted list, they’ll confiscate it.
But if the item is harder to detect, they’ll manually inspect your bag.
And, if they do open your luggage, they’ll leave a note letting you know.
I recommend being extra careful with certain items, even if they are technically allowed in checked luggage, to avoid unwanted surprises.

What You Can’t Pack in Your Checked Baggage
Here’s a handy list of items that should never go in your checked luggage.
These include dangerous goods, electronics, and flammable materials:
Tools and Electronics:
- External Power Chargers & Power Banks (these must go in your carry-on)
- Lithium batteries (especially those over 100 watt-hours)
- E-Cigarettes & Vaping Devices (carry-on only)
- Cordless hair straighteners that contain lithium metal or lithium ion batteries or are gas or butane fueled.
Food & Drinks:
- Cooking Sprays (they’re flammable)
- Alcoholic Beverages Over 140 Proof (think grain alcohol!)
Flammable Materials:
- Liquid Bleach
- Spray Paint and Aerosols
- Fuel (butane, propane, gasoline)
Weapons & Explosives:
- Firearms (unless you’re law enforcement)
- Fireworks and Flares (nope, not in checked baggage)
- Realistic Replica Explosives (that’s a big no)
Other Prohibited Items:
- Live Fish and Coral
- Medically Necessary Personal Oxygen (should be packed as a carry-on)
- Bear Spray (unless under certain limits)
Things to Keep in Your Carry-On
It’s always a good idea to avoid packing precious items in your checked luggage. Think about things like jewelry, electronics, medication, and money. You don’t want to risk losing them in case your luggage goes missing!
Here are some items I personally always keep in my carry-on:
- Jewelry (trust me, it’s safer with you)
- Medication (always carry your important meds on board)
- Expensive Electronics (laptops, phones, tablets)
- Important Documents (keep them close to you)
International Travel: Extra Caution

When traveling internationally, be extra cautious about what you pack. Some countries have stricter rules than others, and items that are allowed in one country might be banned in another. For example, dangerous materials, illegal substances, and sharp objects are a no-go.
Make sure to check with your airline and review the regulations for your destination country before packing.
What to Do With Restricted Items?
If you absolutely need to bring something that’s restricted, there are a few options:
- Check with your airline to see if they offer special handling or packaging.
- Ship it separately: Some courier services can help you send your item to your destination.
- Leave it at home: Sometimes it’s just easier to buy it when you arrive!
Final Thoughts
Packing smart can make all the difference in ensuring a smooth and stress-free journey.
By knowing what’s allowed (and what’s not), you can avoid complications at the airport.
And let’s be real, no one wants to deal with having their items confiscated or worse, facing fines.
