Toiletries are one of the trickiest parts of packing for a flight. Liquids rules limit what you can carry on, bottles can leak and full-size products take up valuable space. With a little planning, you can pack everything you need and pass through security smoothly.
This guide explains liquids rules, travel bottles, solid alternatives and packing tips. Rules differ by country and change over time, so check the TSA and your departure airport’s guidance before you fly.
The TSA 3-1-1 Rule
For flights from US airports, the TSA’s 3-1-1 rule applies to liquids, gels, aerosols, creams and pastes in carry-on bags:
- 3.4 ounces (100 milliliters) or less per container
- 1 quart-sized clear, resealable bag
- 1 bag per passenger
Containers must be 3.4 ounces or less even if they are only partly full. Many other countries use similar limits. Some airports with newer scanners have changed screening procedures, but rules vary, so check before you go.
Exceptions
The TSA allows certain items in larger amounts, such as medically necessary liquids and baby formula, breast milk and juice for infants, subject to screening. Declare these items at security. Check TSA guidance for details.
What Counts as a Liquid?
Many items count, including:
- Shampoo and conditioner
- Lotions and creams
- Toothpaste
- Liquid makeup and mascara
- Gels and hair products
- Aerosols like dry shampoo and deodorant sprays
- Peanut butter and similar spreads
When in doubt, put it in your liquids bag or pack it in checked luggage.
Travel Bottles
Types
- Silicone squeeze bottles: Flexible and easy to use, though they can leak if overfilled
- Hard plastic bottles: Durable and good for thinner liquids
- Pump and spray bottles: For lotions and sprays
- Small jars: For creams
Tips
- Label bottles clearly
- Fill only partly to leave room for pressure changes
- Test for leaks before you travel
Solid Toiletries
Solid products do not count toward liquid limits under TSA rules, saving space in your liquids bag:
- Shampoo and conditioner bars
- Bar soap
- Solid deodorant sticks
- Toothpaste tablets
- Solid perfume
- Lotion bars
Store solids in tins or containers so they dry between uses.
Preventing Leaks
- Squeeze out air before closing soft bottles
- Place plastic wrap under caps of full bottles
- Tape caps closed
- Pack liquids in a zip bag even in checked luggage
- Pack liquids upright where possible
Medications
- Keep medications in your carry-on
- Use original containers or bring labels where possible, especially internationally
- Bring copies of prescriptions if traveling abroad
- Check destination rules for medication imports
This is general information; talk with your pharmacist or healthcare professional about travel with specific medications.
Toiletry Bag Types
- Hanging toiletry bags with hooks are handy in small bathrooms
- Flat organizers pack easily in carry-ons
- Clear bags speed security screening
Keep your liquids bag separate so you can remove it at security if required.
What to Leave at Home
- Full-size products you can buy at your destination
- Hotel-provided items like shampoo and soap, if available
- Duplicates
Checked Bag Toiletries
Full-size liquids are generally allowed in checked bags, with limits on some items such as aerosols and flammable products. Check TSA and airline rules. Pack liquids in sealed bags to protect clothing.

Toiletries for Kids
Pack kid-friendly sunscreen, toothpaste and bath items in travel sizes. Baby items like formula follow special TSA guidance. See luggage for families.
Refilling on the Road
On long trips, buy toiletries locally and refill travel bottles.
Building a Ready-to-Go Toiletry Kit
Frequent travelers often keep a toiletry kit packed at all times. Fill travel bottles with your usual products, add a spare toothbrush, deodorant and basic first-aid supplies, and refill items after each trip. A ready kit saves time and reduces forgotten items.
Sustainable Options
- Refillable bottles instead of disposable travel sizes
- Solid bars that reduce packaging
- Reusable containers for creams and cotton pads
Common Mistakes
- Packing full bottles that leak during pressure changes
- Forgetting that toothpaste and lip gloss count as liquids or gels
- Burying the liquids bag deep in the carry-on
- Packing medications in checked luggage
Toiletries for Long Trips
On trips longer than a week or two, your travel bottles may run out. Plan to buy toiletries at your destination, or use solid bars that last longer than small liquid bottles. Pharmacies and supermarkets abroad often carry familiar brands, though products and labels may differ. Keep enough of any specialized product you rely on.
Security Line Tips
Have your liquids bag ready at the top of your carry-on. Wear easy-to-remove shoes and keep pockets empty. If you are enrolled in an expedited screening program, check its current rules, since procedures can differ from standard lanes.
Keeping Toiletries Organized at Your Destination
Hang your toiletry bag on a hook or towel bar in small bathrooms to keep counters clear. Return items to the bag after each use so nothing is left behind at checkout. Before leaving a hotel or rental, check the shower, counter and drawers for forgotten items, especially chargers and small bottles.
