If you’re flying to one of America’s most popular cities for the Fourth of July — Chicago, Denver, New York, Orlando, or San Juan — you’re probably already thinking about what to pack. Fireworks, summer outfits, maybe even a flag or two. But before you zip up your suitcase, take a moment to double-check what you’re putting in your carry-on bag. The last thing you want is to start your holiday weekend by having something confiscated at security.
Here’s a quick guide to five common items that you shouldn’t pack in your carry-on when flying for the Fourth of July, according to the Transportation Security Administration (TSA). This will save you time, frustration, and maybe even some money.
Why packing smart matters
The Fourth of July is one of the busiest travel weekends of the year. Airports in Chicago, Denver, New York, Orlando, and San Juan will be packed with families, solo travelers, and everyone in between heading out to celebrate. Security lines are longer, and TSA officers are extra vigilant for prohibited items.
Knowing what not to pack in your carry-on helps you move through security quickly. It also keeps you from losing valuable or sentimental items that can’t be returned once confiscated.
TSA maintains a full searchable list of what you can and cannot bring on its website, which you can check here. Below are five items that often catch travelers off guard, and tips on what to do instead.
1. Fireworks
This one might seem obvious, but many people still try to bring fireworks in their carry-on bags — especially over the Fourth of July. Maybe you picked up some sparklers or small firecrackers to use when you land. Unfortunately, TSA prohibits all fireworks in both carry-on and checked luggage.

That includes sparklers, firecrackers, roman candles, and any other pyrotechnic device. They are considered flammable and explosive, which makes them unsafe to bring on an aircraft. If you really want to use fireworks when you arrive, buy them locally after you land. You’ll likely find plenty of roadside stands and stores selling them in the days leading up to Independence Day.
2. Aerosol insecticides
If you’re heading somewhere tropical or humid like Orlando or San Juan, packing insect repellent makes sense. But not all repellents are TSA-friendly. Aerosol insecticides are not allowed in your carry-on bag.

TSA considers aerosol insecticides hazardous because they are pressurized and flammable. You can, however, pack them in your checked luggage as long as they’re not labeled as hazardous material. If you prefer not to check a bag, consider bringing insect repellent wipes or a small liquid spray bottle that’s under 3.4 ounces. Those are allowed in carry-on bags and fit into your quart-sized liquids bag.
3. Axes and hatchets
Planning some camping or hiking while you’re in Denver or around Chicago’s forest preserves? You might be tempted to pack an axe or hatchet for splitting firewood or clearing brush. But sharp tools like these are not allowed in carry-on bags.

Any kind of blade, especially one as large and heavy as a hatchet, is considered a security risk in the cabin. TSA recommends placing axes, hatchets, and similar tools in checked luggage instead. If you’re not checking a bag, you might also consider renting or buying these tools at your destination instead of traveling with them.
4. Ammunition
If your Fourth of July plans include target shooting or you’re traveling to an area where firearms are permitted, you might also need ammunition. Just remember, you cannot carry ammunition in your carry-on bag under TSA rules.

Small arms ammunition is only permitted in checked luggage and must be packed securely in a box designed for carrying ammunition. You’ll also need to check with your airline to confirm how much you can bring and what additional requirements they have. Firearms themselves have even stricter rules, and you should review TSA’s firearms guidelines before traveling.
5. Alcoholic beverages over 140 proof
It’s not unusual to bring a little something to toast the holiday, but make sure you’re following the rules. Alcoholic beverages with more than 70% alcohol content (over 140 proof), such as grain alcohol or some rums, are prohibited in both carry-on and checked luggage.

Anything under 70% alcohol can be packed, but carry-on limits still apply. If you’re bringing mini liquor bottles in your carry-on, they have to fit into your quart-sized liquids bag and each must be 3.4 ounces or less. Be mindful of the Federal Aviation Administration’s rules about drinking alcohol on planes — you can’t consume alcohol you brought yourself on board unless served by a flight attendant.
Tips for smooth security screening
Knowing what you can’t pack in your carry-on is just one part of the equation. Here are some additional tips to help you breeze through security:
Check the TSA website before you pack. Their What Can I Bring page is updated regularly.
Pack liquids properly. Keep them in containers of 3.4 ounces or less, all in one quart-sized clear bag.
Be ready to remove electronics. Laptops, tablets, and sometimes even food items may need to be screened separately.
Arrive early. On busy holiday weekends, give yourself extra time at the airport.
Ask TSA if unsure. You can tweet @AskTSA or send them a message on Facebook if you’re not sure about a specific item.
Celebrate responsibly
Whether you’re watching fireworks over Lake Michigan in Chicago, enjoying the Rockies in Denver, taking in the skyline in New York, visiting the theme parks in Orlando, or soaking up the sun in San Juan, the Fourth of July is a great time to travel. Just make sure your holiday starts off on the right foot by packing smart.
Prohibited items can delay your screening process and even result in fines or confiscation. When in doubt, leave it at home or pack it in your checked luggage if allowed.
Final thoughts
Traveling for the Fourth of July can be exciting and hectic. The last thing you want is a hold-up at the security checkpoint because of an item you didn’t realize was prohibited. Fireworks, aerosol insecticides, axes and hatchets, ammunition, and high-proof alcohol are five of the most common items you should never pack in your carry-on.
Planning ahead will save you time and hassle. Always double-check your bags before you leave for the airport, and make sure you’re familiar with TSA’s guidelines. That way, you can focus on enjoying the festivities and making the most of your holiday weekend.
Happy travels and happy Fourth of July!
