What You'll Learn

Packing tips to get through security smoothly
Packing your luggage strategically can significantly speed up your time at security. Here are some tips to get through airport security smoothly:
Plan ahead
If your schedule allows, try to travel during off-peak hours. Early mornings, late evenings, and midweek flights tend to be less crowded, resulting in shorter lines and a faster security experience. It is recommended to arrive at the airport at least two hours before a domestic flight and three hours before an international flight. This allows you to address any unexpected issues calmly, such as long lines or additional screenings.
Know the rules
Knowing the rules can prevent the inconvenience of discarding items or undergoing further inspections. For example, powder-like substances greater than 12 oz/350 ml must be placed in a separate bin for X-ray screening and may require additional screening. Liquids should follow the 3-1-1 rule: 3.4 ounces or less per container, all containers in a 1-quart plastic bag, and one bag per traveller.
Pack efficiently
Keep your electronics and liquids easily accessible. Use packing cubes or clear bags to compartmentalise your items. This makes it easier to find and remove necessary items when required. Avoid overpacking, as a cluttered bag can lead to longer screening times and potential delays.
Dress appropriately
Choose clothing and shoes that are easy to take off and put back on. Avoid wearing belts, jewellery, or complicated shoes that require a lot of effort to remove. Instead, opt for slip-on shoes and minimal accessories to make the process smoother.
Stay calm and polite
Remaining calm and polite can positively impact your security experience. Security personnel are there to ensure everyone's safety, and cooperating with their instructions can expedite the process. Remember that everyone is trying to get to their destination, and a little patience can make the experience more pleasant for everyone.

International travel rules
When travelling internationally with protein powder, it is important to be aware of the rules and regulations of your destination country, as well as any countries you will be transiting through. While protein powder is allowed in both carry-on and checked luggage, different countries may have varying restrictions on the importation of food products.
If your protein powder exceeds 12 ounces (350ml) in your carry-on luggage, it will need to be placed in a separate bin for X-ray screening. This rule applies to both domestic and international flights. The powder may trigger a secondary screening process, where TSA agents will perform additional checks and may need to open the container to evaluate its contents. To streamline this process, it is recommended to use single-serving packets or the original container for your protein powder. Alternatively, you can use resealable or freezer ziploc bags, which are more space-efficient and help identify the contents for TSA agents.
To avoid potential mess and spills, opt for sturdy, airtight containers such as plastic screw-top containers, metal canisters with latching lids, or silicone sealable bags. Packing your protein powder in a checked bag may also be more convenient and efficient, especially if you are concerned about meeting TSA requirements.
Some travellers may prefer to avoid bringing protein powder altogether and opt for protein-rich snacks or meals before their flight. Protein bars, cheeses, and baked goods are all TSA-friendly options that can be easily carried through security checkpoints. Additionally, you can check if your destination offers a variety of protein powder options for purchase, allowing you to buy it when you arrive.

TSA rules for carry-on and checked bags
The Transportation Security Administration (TSA) has specific rules and guidelines for carry-on and checked baggage to ensure the safety of passengers and staff. Here are the key TSA rules for each type of baggage:
Carry-on Baggage:
- Liquids, Gels, and Aerosols: The TSA has a 3-1-1 rule for liquids, gels, and aerosols in carry-on baggage. Each passenger is allowed to carry liquid items that are 3.4 ounces or 100ml in size. These items should fit comfortably in a 1-quart-sized, clear plastic bag. This includes items like shampoo, toothpaste, hair gels, and aerosols like hairspray.
- Electronics: All personal electronic devices larger than a cell phone, such as laptops, tablets, e-readers, and handheld game consoles, must be removed from carry-on bags and placed in a separate bin for X-ray screening.
- Prohibited Items: Sharp objects, such as knives, scissors, and razors, are not allowed in carry-on baggage. Firearms and other weapons are also prohibited. Hazardous materials, including explosives and flammable substances, are strictly forbidden.
- Food and Powders: Solid foods, such as fruits, health bars, and sandwiches, are typically allowed in carry-on bags. However, powder-like substances, including protein powders, that are greater than 12 ounces or 350 ml, may require additional screening and are encouraged to be placed in checked bags.
Checked Baggage:
- Firearms: Firearms are only permitted in checked baggage and must be unloaded, placed in a locked, hard-sided container, and declared to the airline.
- Locks: When purchasing a lock for your checked baggage, look for those that are TSA-recognized. TSA has master keys that can open certain branded locks to inspect baggage without cutting them.
- Inspection Notices: If your checked baggage is physically inspected by a TSA officer, they will place a notice of baggage inspection inside your bag.
- Hazardous Materials: Similar to carry-on baggage, most hazardous materials are not allowed in checked bags. This includes explosives, pressurized gases, and flammable liquids.
- Powders: It is recommended to place non-essential powder-like substances greater than 12 ounces or 350 ml in checked bags to avoid additional screening at the checkpoint.
It's important to note that the final decision on whether an item is allowed through the checkpoint rests with the TSA officer. Passengers are encouraged to arrive early at the airport to allow sufficient time for the screening process and to cooperate with TSA officers' instructions.

Alternative protein sources for travel
While it is possible to take protein powder through airport security, there are a few things to keep in mind. Powder-like substances over 12 oz/350 ml must be placed in a separate bin for X-ray screening, and their containers may need to be opened. To avoid this inconvenience, some travellers suggest buying a small pack of protein powder at your destination, or placing non-essential powders in checked bags. If you do decide to bring protein powder in your carry-on luggage, it is recommended to use a sturdy, airtight container to prevent leaks and spills. Plastic screw-top containers or metal canisters with latching lids can be good options. Alternatively, you can use silicone sealable bags or vacuum-sealed storage bags to maximise space in your luggage.
If you are looking for alternative protein sources for travel, there are several portable, protein-rich foods that can fuel your journey:
- Chicken pouches: Fully cooked chicken pouches, such as StarKist's, offer 13g of protein for only 80 calories. They are shelf-stable, convenient, and make for a tasty snack.
- Trail mix: Create your own trail mix with nuts and protein-rich cereal. This provides protein, fibre, and healthy fats to stabilise your energy levels and reduce cravings.
- Protein bars: These bars are designed to be a convenient and nutritious option when you're on the go.
- Cheese sticks and snacks: Cheese is a good source of calcium and protein, supporting your energy and bone health. Cheese sticks or pre-wrapped cheese snacks are easy to toss into your bag.
- Jerky: Jerky is a classic travel snack, offering protein and flavour to keep you satisfied during your trip.
- Protein oats: For long flights, you can pack a ziplock bag of dry oats and protein powder. Ask for hot water on the plane and mix your own meal. You can also add crushed nuts, chia seeds, hemp seeds, or dried fruit.
- Protein chips: Instead of regular potato chips, opt for protein-packed versions like Quest Protein Chips, Crisp Power Protein Pretzel Crisps, or Kindling Protein Pretzels. These provide a crunchy and filling option with added protein and fibre.

What to do if you need a large quantity
If you need to travel with a large quantity of protein powder, it is recommended that you place it in your checked luggage. According to the Transportation Security Administration (TSA), non-essential powders exceeding 12 ounces (350 mL) in carry-on luggage must be declared and may be subject to additional screening. They may even ask you to separate it from the rest of your luggage during the security screening. To avoid any potential issues, it is best to pack large quantities of protein powder in your checked bags.
When packing protein powder in checked luggage, make sure to follow the guidelines and regulations of the country you are travelling to. While protein powder is generally allowed in both carry-on and checked luggage, some countries may have specific restrictions. It is always a good idea to check beforehand to ensure a smooth travel experience.
To facilitate the screening process, consider using single-serving packs or the original container for your protein powder. This will make it easier for TSA officers to identify and inspect the contents. If you are using a different container, clearly label it as "whey protein" or "protein powder" to avoid any confusion.
Additionally, you can divide the powder into multiple large Ziplock bags. This helps to reduce the amount of air pressure that can build up during travel and also makes it easier to pack. However, some travellers have reported that using Ziplock bags may attract extra attention from customs officers, so it is important to be prepared for potential additional screening.
Finally, consider alternative options to reduce the amount of protein powder you need to carry. For example, you could send the protein powder to your destination in advance, especially if you are staying at a hotel or with family. Alternatively, you can buy protein powder when you arrive, as it is available in many places, especially tourist spots or fitness-oriented cities.
