Airport security regulations vary by country and airport, so it's always a good idea to check the specific rules for your departure airport and destination country before travelling. In general, solid foods like sweets are permitted in hand luggage, but they may be subject to additional screening if they trigger an alarm or pose security concerns. Liquids, on the other hand, are subject to strict restrictions. Most airports limit the amount of liquid allowed in hand luggage to containers of 100ml or less, although some airports allow up to 2 litres. These restrictions apply to drinks, soups, jams, toiletries, cosmetics, sprays, pastes, gels, and contact lens solutions. It's important to note that food items and powders can obstruct X-ray images, so your bags may need to be manually checked by security.
| Characteristics | Values |
|---|---|
| Liquids | Liquids are permitted in hand luggage, but there are restrictions on the amount. Liquids must be in containers no larger than 100ml and must fit comfortably inside a clear, resealable plastic bag. Some airports may allow containers up to 2 litres. |
| Food | Solid foods are generally allowed, but sauces may be considered liquids. Food items can obstruct X-ray images, so bags may need to be checked manually. |
| Dangerous items | Anything considered dangerous by airport security staff will not be allowed, even if typically permitted in hand luggage. |
| Electronic items | Small electronic items like mobile phones, iPods, and laptops can be kept in hand luggage. Larger items, such as tablets, may need to be screened separately outside the bag. |
| Medical items | Essential medical items are allowed with a prescription or doctor's note. This includes liquid medicines and food for special dietary requirements. |
| Duty-free items | Liquids bought at duty-free shops can be taken through security if sealed inside a security bag with the receipt visible. |

Powders and delays
Powder-based substances in carry-on baggage above a certain quantity may require additional screening at checkpoints. For instance, since June 30, 2018, passengers travelling to the US with powder products larger than 350 ml (12 oz) in their hand luggage may face restrictions. These powders may be disposed of if they cannot be resolved at the central checkpoint.
Some travellers have reported varied experiences with carrying powders through airport security. While some have faced no issues with powdered makeup, laundry detergent, or protein powder, others have experienced additional scrutiny or had their items snapped or dropped by security personnel.
To avoid delays and ensure a smooth journey through airport security, it is advisable to check the latest guidelines and restrictions for the specific airport and country of travel. Placing powders in checked baggage or hold luggage can help streamline the security screening process and minimise potential delays.

Dangerous items
The Transportation Security Administration (TSA) is the government agency responsible for the traveling public in the U.S. and is focused on preventing dangerous items from being carried onto airplanes. While there are no explicit mentions of sweets being prohibited, food items and powders can obstruct images on X-ray machines, which may cause delays.
- Firearms: Special instructions are provided for carrying firearms and ammunition. These items are typically prohibited in carry-on baggage but may be allowed in checked baggage under certain conditions.
- Hazardous Materials: This includes items such as flammable liquids, compressed gases, and corrosive substances. These are typically prohibited in both carry-on and checked baggage.
- Sharp Objects: Items such as knives, scissors, and razor blades are not allowed in carry-on baggage due to their potential use as weapons. However, they may be permitted in checked baggage.
- Explosives and Flammable Substances: Items such as fireworks, flares, and lighter fluids are strictly prohibited in both carry-on and checked baggage.
- Sporting Equipment: Certain sporting equipment, such as baseball bats, golf clubs, and ski poles, may be subject to restrictions due to their potential use as weapons. These items are typically allowed in checked baggage but may need to be transported in a specific manner.
It is important to note that even if an item is generally permitted, it may be prohibited if it triggers an alarm during screening, appears tampered with, or poses security concerns. The final decision rests with the TSA officer at the checkpoint. Passengers are advised to plan ahead, pack properly, and familiarize themselves with the restrictions to facilitate a smooth screening process.

Electronics
When it comes to electronics, there are a few things to keep in mind when passing through airport security. Firstly, it is important to ensure that all your electronic devices are fully charged before reaching the airport. This is because an uncharged device might be considered a security risk, as explosives or other prohibited substances could be hidden in the battery compartment. If a device cannot be turned on when requested, you may not be allowed to take it on board. Most airports have charging stations, so you can always charge your devices before passing through security if needed.
Another important point to remember is that you will likely need to remove electronic devices from your hand luggage when going through security. This is to ensure that the devices can be screened separately and that they do not obstruct the X-ray images of other items in your bag. Generally, any electronic devices larger than a cell phone or camera will need to be removed and placed in a separate bin for X-ray screening. This includes items such as laptops, tablets, e-readers, handheld game consoles, and cameras. It is recommended to keep your electronics easily accessible to facilitate a smoother security process.
Some airports have implemented advanced 3D X-ray machines that may not require the removal of electronics from your bag. However, it is always a good idea to check with your specific airline or airport beforehand, as requirements may vary. Additionally, certain countries may have unique security processes that differ from those of other nations. For example, one person reported that they were required to remove electronics from their backpack in an airport in India.
When travelling with electronic devices, it is also crucial to be aware of any restrictions or requirements for your destination country. Some countries may have specific regulations regarding the types or quantities of electronics that can be brought into the country. Checking the website or contacting the relevant embassy or customs office of your destination country can help you stay informed about any applicable rules and avoid potential issues during your travel.
Lastly, it is worth noting that there may be additional screening procedures for flights departing to the United States. The U.S. Department of Homeland Security has been working to enhance aviation security measures at foreign airports with direct flights to the U.S., which may result in a more extensive screening process for personal electronic devices. Therefore, if you are travelling to the U.S., it is advisable to arrive at the airport early to allow sufficient time for any necessary checks.
