The Transportation Security Administration (TSA) has strict rules about what can and cannot be taken through airport security. Liquids, gels, and creams are subject to the 3-1-1 rule, which means that they must be in containers of 3.4 ounces (100ml) or less and fit in a quart-sized bag. During the COVID-19 pandemic, hand sanitizers were exempt from this rule, but that has since changed, and now only containers of up to 12 ounces are permitted.

The Transportation Security Administration (TSA) allows up to 12 ounces of hand sanitizer
The Transportation Security Administration (TSA) has specific rules regarding what travellers can and cannot bring on board a plane. Liquids, gels, creams, and aerosols are allowed on board, but only in small quantities. Typically, the limit is 3.4 ounces (100 ml) per item, and all such items must fit in a quart-sized bag. This is known as the 3-1-1 rule.
However, in light of the COVID-19 pandemic, the TSA has made an exception for hand sanitizer. Passengers are now allowed to bring hand sanitizer containers up to 12 ounces in size on board. This is significantly larger than the standard allowance and is indicative of the unique circumstances brought about by the pandemic. It is important to note that this updated policy only applies to hand sanitizer and that larger containers will be subject to additional screening by TSA agents.
The TSA's primary concern is the safety of passengers and crew. As such, they have implemented rules regarding hazardous materials, also known as dangerous goods. These items, which include explosives, flammable liquids, and toxic substances, can pose a significant threat when transported by air. Even everyday items like lithium batteries and aerosol cans are regulated as hazardous materials.
The TSA is continually adapting its policies to address emerging risks. For example, in 2025, the TSA issued a warning prohibiting camping stoves with propane tanks in both carry-on luggage and checked baggage. This decision was made following an incident at Pensacola International Airport, where a stove with a gas cartridge was detected in a carry-on bag.
It is essential for travellers to stay informed about the latest TSA regulations to ensure a smooth and safe journey. Resources like the TSA's website and social media channels can provide valuable information on prohibited items and security measures. Additionally, travellers should be cautious when using technology at the airport, as unprotected USB charging ports and unsecured Wi-Fi networks can pose cybersecurity risks.

Containers over 3.4 ounces will be subject to additional screening
The Transportation Security Administration (TSA) has specific rules regarding the amount of liquid allowed on planes. Liquids, gels, creams, and pastes are limited to travel-sized containers of 3.4 ounces (100ml) or less in carry-on luggage. These items must be placed in a separate quart-sized bag for screening.
However, due to the COVID-19 pandemic, the TSA implemented a temporary exemption for hand sanitizers, allowing containers of up to 12 ounces (355ml) in carry-on bags. While this policy has since been revoked, and hand sanitizer now falls under the standard 3-1-1 rule, containers over 3.4 ounces will be subject to additional screening.
If you plan to bring a large container of hand sanitizer, be prepared for the additional screening process, which may include further inspection and testing for explosives. The screening process may take longer, so it is advisable to consider how much sanitizer you truly need for your trip. Additionally, keep in mind that TSA rules for liquids do not apply to duty-free liquids purchased internationally and transported in secure, tamper-evident bags.
It is important to note that the TSA's additional screening procedures are in place to ensure the safety and security of all passengers. These procedures may include opening containers, testing liquids, and using advanced screening technologies. Passengers with medical or child-care needs may also be exempt from certain restrictions, but it is always advisable to check the latest TSA guidelines before your travel.

TSA agents will confiscate prohibited items
The Transportation Security Administration (TSA) has strict rules about what can and cannot be taken through airport security. TSA agents will confiscate prohibited items. This includes items that are considered dangerous goods or hazardous materials. If you are unsure about an item, it is best to leave it at home or risk losing it at the airport.
Other prohibited items include explosives, gases, flammable liquids and solids, oxidizers, toxic and infectious materials, and radioactive materials. These items are strictly forbidden and will be confiscated by TSA agents. It is important to check the latest list of prohibited items before travelling, as the rules can change.
In addition to physical items, TSA agents will also confiscate electronic devices if they are found to contain contraband. Customs officers may search people's electronic devices, such as laptops and cell phones, for contraband or other suspicious content. To protect yourself, it is recommended to avoid charging your devices through USB ports at the airport and to avoid entering personal details when connected to public airport Wi-Fi.
TSA agents are there to ensure the safety and security of all passengers. By confiscating prohibited items, they help to mitigate risks and ensure a safe travel experience for everyone. It is important to cooperate with TSA agents and follow their instructions to ensure a smooth and efficient screening process.

Other hazardous materials include lithium batteries and aerosol whipped cream
Passengers are allowed to bring hand sanitiser containers of up to 12 ounces (355 millilitres) in their carry-on luggage. This is significantly larger than the standard allowance of 3.4 ounces (100 millilitres) for liquids, aerosols, creams and gels. However, larger containers of hand sanitiser will be subject to additional screening, which may increase wait times.
Other hazardous materials that are subject to restrictions include lithium batteries and aerosol whipped cream. Lithium batteries that are installed in devices like laptops and phones are generally allowed in carry-on luggage. However, spare lithium-ion and lithium-metal batteries, including power banks and charging cases, must be carried in carry-on baggage only. With airline approval, passengers may carry up to two spare larger lithium-ion batteries (101-160 Wh) or lithium-metal batteries (2-8 grams). This covers larger batteries used in laptops, cameras, phones, and professional audio/visual equipment.
Aerosol whipped cream, on the other hand, falls under the category of aerosols, which are allowed in carry-on luggage but in limited quantities. Passengers are typically permitted to bring a quart-sized bag of aerosols, creams, and other similar items in their carry-on baggage. These items must be in travel-sized containers of 3.4 ounces (100 millilitres) or less. Larger containers should be packed in checked baggage. Any items that alarm during screening will require additional screening and may be subject to further restrictions.

COVID-19 test kits without diagnostic samples are allowed in carry-on and checked baggage
The COVID-19 pandemic has brought about several changes in airport security protocols. One of the most notable changes is the allowance of hand sanitizers on board flights. Passengers are now permitted to carry hand sanitizer containers of up to 12 ounces (355 milliliters) in size, which is significantly larger than the standard 3.4 ounces (100 milliliters) previously allowed. This updated policy is a response to the increased emphasis on hygiene and sanitation to curb the spread of the virus.
While hand sanitizers are now allowed, it is important to note that they are subject to specific regulations. The policy only applies to hand sanitizer, and larger containers will be scrutinized further by TSA agents, potentially causing delays. Therefore, it is advisable to consider the amount of sanitizer one needs before heading to the airport. Additionally, passengers should be aware that hand sanitizer stations are readily available throughout most airports, reducing the need to carry large quantities.
Apart from hand sanitizers, other items have also undergone scrutiny due to safety concerns. The Transportation Security Administration (TSA) has implemented rules regarding prohibited items that pose security threats. For instance, portable chargers and power banks with lithium batteries are now banned from checked luggage due to their fire risk. These items must be carried in carry-on baggage only, and any spare lithium batteries should be kept with passengers in the aircraft cabin.
Amid the pandemic, COVID-19 test kits have also been the subject of scrutiny. Unused COVID-19 test kits, which do not contain dangerous goods, are typically allowed in both carry-on and checked baggage. However, test kits containing diagnostic samples, such as nasal swabs and vials of sputum, are prohibited in carry-on baggage. These samples must be appropriately packaged, handled, and identified as a UN3373 Category B Infectious Substance during transportation. Passengers intending to travel with such samples should consult their carrier before packing them in checked baggage or shipping them as cargo.
In conclusion, while hand sanitizers are now permitted onboard flights, with certain restrictions, COVID19 test kits without diagnostic samples can be carried in both carry-on and checked baggage. Passengers should remain vigilant about other safety protocols and be mindful of any updates or changes in regulations to ensure a smooth and safe travel experience.
