Bringing A Toiletry Bag On A Plane — Rules That Matter

Think of your toiletry kit as two parts: what flies in your carry-on and what rides in checked baggage. The line between the two comes down to liquid size, aerosol caps, and sharp edges. Stick to travel sizes in the cabin, and send bulk items below.

In the U.S., the TSA 3-1-1 rule caps any liquid, gel, cream, or paste at 3.4 ounces (100 ml) and asks you to place those little containers inside one clear, quart-size bag. Toothpaste, shampoo, conditioner, mouthwash, lotion, and many cosmetics count toward that bag. Full-size bottles live in checked bags.

Flying through the UK or the EU? Many airports still apply the 100 ml cap for hand luggage, while some lanes with new scanners use different steps. When you’re not sure, follow the 100 ml standard and check your departure airport’s page. The UK CAA guidance and this European Commission notice explain the current limits across many terminals.

Carry-On Toiletry Bag: What Goes Inside

Build your quart-bag with the items you’ll use mid-flight or within the first day. That might be toothpaste, face wash, contact solution, lip balm, a tiny moisturizer, and travel-size sunscreen. Add a small aerosol like hairspray or shaving cream if you need it; keep each can at 3.4 ounces or under and make sure the cap covers the nozzle.

Solid toiletries don’t count toward 3-1-1. Bar soap, stick deodorant, solid cologne, shampoo bars, and makeup wipes can ride outside the liquids bag. This swap frees space for liquids you can’t replace easily at your stop.

Checked Toiletry Bag: What Belongs Down Below

Anything full-size goes in the hold: family-size shampoo, big tubs of cream, large aerosols, and refill pouches. Tighten caps, tape flip-lids, and slip bottles into a zip bag. Cabin pressure shifts can nudge lids open; a simple liner bag saves a suitcase.

Blades live here too. Safety razor blades and loose straight-razor blades don’t pass the checkpoint, but they’re fine in your checked kit inside a blade cover or a small hard case.

Toiletry Rules By Item Type

The quick chart below shows common items and where they belong. Use it to pack faster and skip repacking at the belt.

Build A Leak-Proof, Checkpoint-Ready Kit

Pick a clear, flat-opening pouch for your cabin bag so officers can see items without digging. A rigid quart-bag keeps tiny bottles upright and reduces crushed caps. If your kit has a hook, you can hang it in tight hotel bathrooms and keep the counter dry.

Choose minis that close cleanly. Flip-tops seep; screw caps tend to hold. If a brand sells the same product in a 100 ml bottle, buy that version instead of decanting. Sticky labels fade; add a strip of masking tape and write the name and fill date.

For decanting, pick leak-tested travel bottles with wide mouths. Fill to about 85% so there’s room for expansion. Snap every cap, then wrap the lid with a quick loop of tape. Place the heaviest bottle near the bottom of the pouch.

Make The 3-1-1 Bag Work Harder

Swap liquids for solids where it makes sense. A bar of face cleanser might replace a bottle. Toothpaste tablets beat a tube for short trips. Solid sunscreen sticks layer well with a tiny SPF gel for touchups.

Scale your kit to the trip. Two nights? One mini shampoo may be plenty. A week? Pack two or plan to top up at your stop. On long runs, carry the first two days of supplies in the cabin and send the rest in checked luggage.

Security Screening: Smooth Steps That Save Time

Before the belt, pull out your quart-bag and place it in a bin with any laptops if your lane asks. Some lanes with CT scanners let liquids stay inside, but steps change by airport and day. When signs say “bag out,” place it on top so officers see it fast.

If an officer wants a closer look, you may be asked to open the pouch and tilt a bottle so they can read the label. Say what the item is, keep lids closed until asked, and you’re on your way.

Blades, Sprays, And Other Edge Cases

Disposable razors pass in carry-ons. Safety razor handles can ride in the cabin, but loose blades cannot. Straight razors belong in checked bags. Scissors are fine in the cabin when the blades measure under four inches from the pivot point.

Aerosol toiletries are allowed in both bag types within size limits. In the cabin, each can still counts toward your quart-bag. In checked bags, typical personal-care aerosols top out at 500 ml (17 fl oz) per can, and caps need to prevent accidental spray.

What To Pack Where: A Simple Split

Use the table below to map your packing by trip length. It keeps the carry-on light and the checked kit thorough.

Smart Extras That Keep Things Tidy

Pack a small roll of tape, a few zip bags, and two spare screw-cap bottles. A tiny funnel saves messes. A microfiber cloth wipes leaks fast. A pen can re-label decanted bottles after a switch.

Add a small first-aid sleeve: a couple of bandages, a few pain tablets in a labeled mini, and a small ointment that fits the quart-bag. Keep any daily meds in original packaging and carry a photo of the label on your phone.

Common Toiletry Bag Mistakes To Avoid

Overpacking the quart-bag leads to a redo at the belt. If it doesn’t zip easily, it’s too full. Split items with a travel partner or plan a quick stop at a store near your stay.

Leaving off caps on aerosols invites a spill. The same goes for pumps without a clip. If a bottle oozes at home, it will ooze on the plane. Swap it or move that product to a better container.

Dropping blades into a pouch unprotected risks cuts during random screening. Use a travel blade bank or slide a guard over the edge. For scissors, a tip cover keeps fabric from snagging.

International Notes When Your Route Is Mixed

Rules match in broad strokes, but small differences can catch you. One airport might ask you to bag liquids and pull out electronics; another may allow your kit to stay inside the bag. If your return airport runs stricter screening, keep spare minis sealed in your checked bag so you don’t lose them on the way back.

If you need to carry larger medical liquids, separate them from the quart-bag and declare them at the belt. Officers screen them with a quick test. Baby milk and foods follow similar steps. Print a short doctor’s note or keep a digital copy in your phone’s files.

Grab-And-Go Packing List For A Standard Trip

Here’s a tight list you can reuse: toothbrush, travel toothpaste, floss picks, face wash, daily SPF, moisturizer, lip balm, stick deodorant, razor or cartridges, hair ties, small brush or comb, travel fragrance, cotton swabs, and a mini laundry soap sheet. Add items that fit your routine, and skip anything you never touch at home.

Place the quart-bag at the front of your personal item. Keep the rest of the kit in your carry-on’s top pocket. If your suitcase gets gate-checked, you’ll still have the items you need for a night.
