What You'll Learn

Liquids, gels, and aerosols over 3.4 oz must be in checked baggage
Liquids, gels, and aerosols are permitted in carry-on luggage only in travel-sized containers of 3.4 ounces (100 milliliters) or less. These must be placed in a quart-sized bag and separated from your carry-on baggage for screening. Any liquid, gel, or aerosol over 3.4 ounces must be packed in your checked baggage. This is a strict rule, and any item over this volume will not be permitted in carry-on luggage, even if it is in a secure, tamper-proof bag.
It is important to note that even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm, appears tampered with, or poses security concerns. This includes liquids, gels, and aerosols. The final decision rests with the TSA officer at the checkpoint.
To ease the screening process and keep lines moving, it is recommended that travelers organize their carry-on bags and keep them uncluttered. This allows for clear images on the X-ray machine and facilitates the screening of liquids, gels, and aerosols. Separating these items from your carry-on bag ahead of time can help speed up the process.
When traveling with liquids, gels, and aerosols over 3.4 ounces, it is important to plan and pack them properly in your checked baggage. This will ensure a smoother travel experience and avoid any issues at the airport security checkpoint. Remember that any liquid, gel, or aerosol that alarms during screening, regardless of volume, will require additional screening.
Additionally, travelers connecting through the United States from international flights can carry duty-free liquids over 3.4 ounces in their carry-on bags. However, these must be purchased internationally and kept in secure, tamper-evident bags. Proper planning and knowledge of the regulations will ensure a seamless travel experience when bringing liquids, gels, and aerosols onto an aircraft.

Containers under 3.4 oz can be in a carry-on bag
When travelling with food and drink, it's important to remember that planning ahead and packing properly can make the screening process easier and improve your overall travel experience. While you can take containers of liquid, gels, and aerosols through airport security, they must be under 3.4 ounces (100ml) in volume. Any containers larger than this must be packed in checked baggage.
To take liquids through security, you must place them in a small, quart-sized bag that is separate from your carry-on baggage. This facilitates the screening process and helps keep the lines moving. It's also important to note that any liquid, gel, or aerosol that alarms during screening will require additional screening.
If you're travelling with duty-free liquids, you can carry them in your carry-on bag if they are in secure, tamper-evident bags and were purchased internationally. However, these items must be screened and cleared, and any item that alarms or cannot be screened will not be permitted.
Ultimately, the final decision rests with the TSA officer on whether an item is allowed through the checkpoint. Officers may instruct travellers to separate items from carry-on bags, such as foods, powders, and other materials that can clutter bags and obstruct clear images on the X-ray machine. So, while you can take containers under 3.4 oz in a carry-on bag, it's important to be prepared for additional screening and follow any instructions from TSA officers.

The TSA officer makes the final decision
Passengers are allowed to bring liquids, gels, and aerosols in their carry-on bags when going through airport security. However, these items must be in containers that are 3.4 ounces (100 milliliters) or less and must fit in a quart-sized bag. Any containers larger than 3.4 ounces or 100 milliliters should be placed in checked baggage. This includes carbonated beverages, such as soda or pop.
It is important to note that even if an item is generally permitted, it may still be subject to additional screening or may not be allowed through the checkpoint if it triggers an alarm, appears to have been tampered with, or raises other security concerns. In such cases, the final decision rests with the TSA officer on whether an item is allowed through the checkpoint.
TSA officers have the authority to make the final call on whether an item poses a security risk and should be prohibited. They may request that travelers separate items from their carry-on bags, such as foods, powders, liquids, and other materials that could clutter the bag and obstruct clear images on the X-ray machine. By keeping their carry-on bags organized and uncluttered, travelers can facilitate the screening process and ensure a smoother experience.
Additionally, TSA officers may ask passengers to power up their electronic devices, including cell phones, to ensure they are functional and do not pose a security threat. This further emphasizes the discretion and responsibility vested in TSA officers to maintain security while allowing passengers to bring essential items onboard their flights.
In summary, while there are general guidelines for what passengers can bring through airport security, the TSA officer ultimately decides whether an item is permitted through the checkpoint. This includes considerations of the item's potential security risk, its impact on the screening process, and any concerns that may arise during the screening. Passengers are advised to plan and pack accordingly, keeping their carry-on bags organized and following any instructions from TSA officers to ensure a smooth and efficient security screening experience.
