For carry-on bags, toiletries (liquids, aerosols, gels, pastes) must be in containers 100ml/100g or smaller, fit in one clear, sealable 20x20cm bag (one per person), and be presented separately at security; larger quantities go in checked luggage, where rules are less strict but still have limits (e.g., 500ml/500g per item, 2L/2kg total for aerosols). Sharp items like razors (except disposable ones) and scissors are often restricted in carry-ons.
We recommend packing all liquids, gels, and aerosols that are over 3.4 oz or 100 ml in your checked baggage, even if they are in a secure, tamper-evident bag. Liquids more than 3.4 oz or 100 ml not in a secure, tamper-evident bag must be packed in checked baggage.
There's no limit on the number of liquid containers you can bring in your hand luggage, as long as each one holds no more than 2 litres. However, metal water bottles must still be emptied before going through security, even at airports where the 100ml rule has been replaced.
As per the guidelines, all carry-on liquids, gels, and aerosols must be in containers of 3.4 oz (100ml) or less, packed in one clear quart-size bag.
Toiletry and medicinal articles
Permitted as carry-on or checked baggage. Toiletry and medicinal articles include aerosols such as hair sprays and deodorants, flammable liquids such as hand sanitiser, perfumes and medicines containing alcohol are permitted.
You can't bring sharp objects (knives, scissors over 4in), weapons, most tools (hammers, drills), firearms, explosives, flammable liquids/aerosols, large lithium batteries, disabling sprays (pepper spray), or large quantities of liquids (over 100ml) in your carry-on; most hazardous materials and large sporting goods are also banned due to security risks, requiring them to be checked.
Aerosols fall into the category of liquids and therefore cannot exceed 100 ml (maximum container capacity). Aerosols containing higher amounts must go in checked baggage, and it is advisable to make sure that the container is tightly closed and protected so that the button is not pressed during the flight.
Yes, for airport security purposes, toothpaste is classified as a liquid, aerosol, or gel (LAG) and must follow the 100ml/3.4oz container rule in carry-on bags, even though it's a paste that holds its shape. This rule applies to all similar items like creams, gels, and sprays, requiring them to fit in a single, clear, resealable plastic bag for screening.
The Transportation Security Administration (TSA) doesn't ask you to keep your medicines in their original prescription bottles. But each state may have its own rules. If you aren't bringing your medicine in its original bottle, bring a copy of the prescription or a letter from your doctor.
Each container must be 3.4 ounces (100 milliliters) or less per item. If you aren't able to stay within those limitations, remember that full-size toiletries can always be purchased upon arriving to your destination - don't inconvenience yourself and waste money by checking a bag if you don't have to!
You can't bring sharp objects (knives, scissors over 4in), weapons, most tools (hammers, drills), firearms, explosives, flammable liquids/aerosols, large lithium batteries, disabling sprays (pepper spray), or large quantities of liquids (over 100ml) in your carry-on; most hazardous materials and large sporting goods are also banned due to security risks, requiring them to be checked.
In addition to screening personal electronic devices separately, including laptops, tablets, e-readers and handheld game consoles, TSA officers may instruct travelers to separate other items from carry-on bags such as foods, powders, and any materials that can clutter bags and obstruct clear images on the X-ray machine ...
If you need more sunscreen than what fits in your carry on, checked luggage is your best bet. You can bring full-size bottles, but there are still limits. The FAA allows up to 70 ounces of liquids per person in checked bags, and no single container can be larger than 18 ounces.
Passengers can now keep liquids in their hand luggage or cabin bag when flying from the majority of UK airports. While the 100ml limit remains at most airports, there is no longer a requirement to put bottles and containers in a clear plastic bag - or remove them from your bags at security.
Place Products into Clear, Quart-sized Bag
You may want to opt for something a little sturdier than a Ziploc that still meets TSA guidelines. Remember, quart size is the largest bag allowed; you can take something smaller.
The "45-minute rule" refers to a productivity technique of working intensely for 45 minutes, followed by a 10-15 minute break, leveraging the brain's natural focus cycles (ultradian rhythms) to prevent burnout and boost efficiency, though it can also refer to airline check-in deadlines or corporate onboarding targets. The work/rest pattern helps maintain concentration, while the airport rule requires check-in 45 mins pre-flight for domestic flights.
During travel
Travellers should carry a copy of their prescription together with a covering letter from their doctor. If supplies are needed whilst abroad, a pharmacy or health care provider should be consulted for advice.
Yes, you generally must declare all medication at customs when entering a country, especially prescription drugs, controlled substances (like opioids, ADHD meds), and even some herbal remedies, keeping them in original packaging with a doctor's note/prescription to avoid seizure, as rules vary by destination (e.g., Australia requires declaration for most meds). Always check the specific requirements of your destination country's border agency before travel to know exactly what's needed, like doctor letters, limits (often 3 months' supply), and if your medicine is even legal there.
You can take as many 100ml bottles as will fit into one single, transparent, resealable plastic bag (approximately 1 liter capacity), with each container being 100ml or less, for a total of one bag per passenger. This rule applies to liquids, aerosols, and gels (LAGs) for international flights and generally for domestic flights in many countries.
**Sprays**: Aerosol deodorants must also be 100ml or less and placed in a clear plastic bag. **Creams and Gels**: These must follow the 100ml liquid rule as well.
TSA allows hand sanitizer in a passenger carry-on bag under the 3-1-1 liquids rule. These are limited to travel-size hand sanitizer containers that are 3.4 ounces (100 milliliters) or less per item. The FAA limits the total amount of restricted medicinal and toiletry articles, including aerosols, in checked baggage.
If you can remember the 3-1-1 liquids rule, you'll never forget how to pack toiletries.
Pressurised containers such as large deodorant cans, hair sprays, or insect sprays are not allowed in hand luggage. They are seen as risky items due to the pressurisation inside the cabin. Small travel-size sprays of 100 ml may be allowed, but larger cans will be removed at security.
Arriving at the airport too late for check-in is probably the most common reason passengers are denied boarding. As a consumer advocate and TPG's ombudsman, my case files are filled with stories from travelers who weren't even aware that there are strict cut-off times for flight check-in.
