If you're planning to bring an extra bag through airport security, it's important to familiarize yourself with the relevant regulations to ensure a seamless travel experience. The number of bags you can bring on board depends on your airline's policies regarding carry-on baggage allowance. While the Transportation Security Administration (TSA) doesn't determine the carry-on allowance, it does set rules for what you can pack in your carry-on luggage. These rules are designed to facilitate the screening process and enhance security during travel.

Liquids: Follow the 3-1-1 rule and use a quart-sized bag for travel-sized containers
It is important to plan ahead and pack properly to facilitate the screening process and ease your travel experience at the airport. This includes being aware of the restrictions affecting your carry-on luggage. While airport security rules tend to be similar worldwide, it is always a good idea to double-check the local rules, especially if you are travelling from an airport outside the United States.
One important restriction to keep in mind is the 3-1-1 rule for liquids. This rule states that you can bring one quart-sized bag of liquids limited to travel-size containers that are 3.4 ounces or 100ml per item. This means that each liquid item, such as shampoo, conditioner, or body wash, must be in a container that holds no more than 3.4 ounces or 100ml. The quart-sized bag allows you to easily consolidate all your liquids in one place, making it convenient to take them out of your carry-on bag when going through security.
The 3-1-1 rule helps standardise the process of carrying liquids and makes it easier for security personnel to screen your liquids. It is important to note that the rule applies to liquids, gels, and aerosols. So, if you are carrying items such as toothpaste, hair gel, or spray deodorant, they also need to adhere to the 3-1-1 rule.
Some airports have implemented new scanners that allow you to leave liquids in your bag during the scanning process. However, it is still recommended to follow the 3-1-1 rule and use a quart-sized bag for your liquids. This ensures that you are prepared for any security measures and helps speed up the screening process.
If you require larger amounts of liquids, gels, or aerosols for medical reasons, these are allowed by the TSA. However, you must declare them to the TSA officers at security and expect additional inspection. It is advisable to carry a doctor's note or prescription as proof of the medical necessity of these items.

Electronics: Expect additional screening for personal devices when flying into the US
When passing through airport security, you may bring an extra bag, such as a carry-on suitcase, backpack, purse, or laptop bag, in addition to your personal item. However, it's important to be mindful of the specific regulations and restrictions enforced by the Transportation Security Administration (TSA). These rules apply to all items in your carry-on luggage.
When it comes to electronics, additional screening procedures are often implemented. Officers may request that you power up your electronic devices, including cell phones and laptops. If your device is powerless, it will not be permitted onboard the aircraft. This measure is in place to address security concerns. As such, it is advisable to ensure your devices are charged before reaching the airport.
Small appliances like electric razors or toothbrushes are generally exempt from removal and can remain in your bag during screening. Starting in 2025, select airports will introduce new scanners that enable passengers to leave their electronics inside their bags during the screening process. However, until this technology is universally adopted, you should anticipate removing your electronics at the checkpoint.
Power banks and portable chargers are restricted to carry-on luggage only and must adhere to a rating of 100 watt hours (Wh) per battery. With airline approval, you may carry up to two larger spare batteries with a maximum capacity of 160 Wh.

Sporting equipment: Check with your airline for specific policies
When travelling with sporting equipment, it is important to check with your airline for specific policies. Each airline may have different rules and restrictions, so it is always good to be prepared. It is advisable to inform your airline as soon as you have booked your flight that you will be travelling with sporting equipment. This can be done by contacting the airline via their website, as some airlines offer an online chat function.
Some airlines may allow certain sports items as hand luggage, while others may require them to be checked in. It is worth noting that some items, such as golf umbrellas, will need to be checked in and will count towards your checked baggage allowance. If you are bringing multiple pieces of equipment, you may need to pay for an extra checked bag. It is best to check with your airline to see if your equipment will be considered checked baggage and if there are any associated fees.
When packing your sporting equipment, planning ahead and packing properly can facilitate the screening process and ease your travel experience. Each airline will have specific weight and size restrictions for checked baggage, so it is important to be aware of these limitations. Some airlines may also have policies regarding the type of container or covering your equipment must be packed in. For example, if you are travelling with Zamzam water, it must be sealed in a plastic covering to prevent leakage.
It is also important to be aware of any restricted items that are not allowed on board an aircraft. These may include sporting equipment with sharp or pointed edges, such as swords or sabres, or items that can be used to cause serious injury, such as bats or clubs. By understanding which items are forbidden, you can plan the contents of your baggage accordingly and ensure a smooth travel experience.

Medical devices: Declare medically necessary liquids to TSA officers
It is important to plan ahead and pack properly to facilitate the screening process and ease your travel experience at the airport. If you are carrying medically necessary liquids, gels, or aerosols, you must declare them to TSA officers at the checkpoint for inspection. This includes liquid medications and associated accessories such as freezer packs, IV bags, pumps, and syringes.
TSA allows larger amounts of medically necessary liquids in reasonable quantities for your flight, but they must be declared and inspected. If you have an insulin pump or glucose monitor, additional screening may be required if it alarms during the WTMD or AIT screening. In this case, a TSA officer will direct you to pat down the medical device and test your hands for any trace of explosives.
You can facilitate the screening of medications in pill or solid form by clearly labeling them. These may be subject to visual inspection, X-ray screening, or testing for traces of explosives. If you do not want your liquid medication to be screened by X-ray or opened, inform the TSA officer, and additional steps will be taken to clear the liquid. This may include AIT screening, a pat-down, and additional screening of your carry-on property.
If you need assistance during the screening process due to a disability or medical condition, you or your travelling companion may speak to a TSA officer about the best way to complete the screening. You can inform the officer verbally, by using a TSA Notification Card, or by providing medical documentation. At TSA PreCheck® lanes, certain items such as liquids do not need to be removed from your carry-on luggage during the screening process.

Location: Rules vary by location, so check local rules when travelling outside the US
While airport security rules tend to be similar worldwide, they can vary by location. So, it's important to check the local rules when travelling outside the US. For instance, while the US allows powders in carry-on baggage, they may be prohibited in other countries. In the UK, food items and powders in hand luggage can obstruct x-ray images, so they may need to be checked manually by security. To minimise delays, you may want to put these items in your hold luggage.
Additionally, while the US allows lighters on board, the UK only permits one lighter, which must be stored in a resealable plastic bag and kept on your person throughout the flight.
It's also worth noting that the US Transportation Security Administration (TSA) has specific rules for carry-on bags, including the 3-1-1 rule for liquids, aerosols, gels, creams and pastes. This rule may differ in other countries, so it's important to check with the relevant airlines and airports before travelling.
Furthermore, if you are flying into the US, you may experience a more extensive screening process, including additional screening of your property and personal electronic devices. This is due to enhanced security measures implemented by the US Department of Homeland Security at foreign airports with direct commercial flights to the US.
To ensure a smooth travel experience, it's always best to research the specific rules and regulations of your destination country and airport.
