Can I bring perfume on a plane in my carry-on luggage?
Yes, you can bring perfume on a plane in your carry-on as long as the bottle is 3.4 oz (100 ml) or smaller, in accordance with the TSA 3-1-1 liquids rule. All bottles must be placed in a single quart-sized zip-top bag. This is applicable across all U.S. airports and airlines, including Delta, United Airlines, and Southwest.
What is the maximum size of liquid containers allowed on a plane?
The maximum container size allowed in carry-on luggage in the USA is 3.4 oz (100ml). Anything larger must go in checked baggage. Even if a larger bottle is half full, TSA considers the total capacity, not the remaining volume. This is critical when packing full-size perfumes or gift box sets.
How many 100ml bottles can I carry in my hand luggage?
As many as will fit in your one quart-sized clear plastic bag, typically 4–6 bottles, depending on shape. All items in the bag must be 100ml or less. Keep in mind, IMIXX Perfumes offers luxury-sized travel bottles in compliant 1 oz (30ml) and 2.5 oz (75ml) formats for U.S. travelers.
Are there restrictions on carrying perfume in checked baggage?
Perfume bottles over 3.4 oz can be packed in checked luggage without restriction. However, it’s important to wrap glass bottles carefully to prevent breakage or leaks. Use bubble wrap or travel cases. Some airlines in the USA may prohibit flammable or pressurized canisters, so check airline guidelines for spray cologne formats.
Do international flights have different rules for carrying liquids?
Most international flights follow similar TSA-based guidelines, especially those departing from or connecting through the USA. However, some airports and countries have stricter limits. Always check both the departure and arrival country’s aviation authority rules. TSA rules apply to all U.S. domestic and international departures.
Can I bring multiple perfume bottles in my carry-on bag?
Yes—as long as each bottle is 3.4 oz or less and all of them together fit inside your one quart-sized TSA bag. For most travelers, this means 3–6 mini bottles. IMIXX USA recommends travel atomizers and their custom 1 oz sizes for maximum flexibility and compliance.
Is solid perfume subject to TSA liquid regulations?
No. Solid perfumes are exempt from the TSA 3-1-1 rule and can be packed without restrictions. They are a great alternative for travelers concerned about liquid restrictions. Some high-end brands offer solid formats of their bestsellers, and IMIXX is currently developing solid options for select designer dupes.
How should I pack perfume to prevent spills during travel?
Use a travel case or bubble wrap to cushion perfume bottles. If placing in checked baggage, double-bag in a zip-top bag to contain leaks. Keep your TSA-approved quart bag easily accessible in your carry-on for security screening in any USA airport.
Are duty-free perfume purchases allowed in carry-on luggage?
Yes, if purchased after security screening, duty-free perfume items are allowed in carry-on—even if larger than 100ml. Always keep the receipt and original packaging, as TSA or connecting flights may request proof. This rule is recognized in U.S. airports, but connecting flights outside the USA may have different restrictions.
FAQs: Perfume and Cologne Travel Rules in the USA
Can I bring cologne on a plane?
Yes, cologne is permitted on planes in the USA. It falls under the TSA’s liquid restrictions, meaning you can carry it in your hand luggage only if it’s 3.4 oz (100ml) or smaller and fits within your quart-sized liquids bag.
How much cologne can I bring on a plane?
You can bring multiple bottles of cologne, as long as:
- Each is 100ml or less;
- They all fit within one TSA-compliant quart-sized zip bag.
For example, two 1 oz colognes and one 2.5 oz bottle would be allowed in most cases.
Can I bring my cologne on a plane?

- 3.4 oz (100ml)
Can I bring a 100ml cologne on a plane?

Yes. Just remember:
- Stick deodorants are not restricted;
