Airport Backpack Essentials: What To Bring And Why

When it comes to air travel, being prepared is key to ensuring a smooth trip. Knowing what to pack in your carry-on bag is essential, especially with budget airlines constantly changing weight limits and bag sizes. Planning ahead and packing properly can make for a more seamless travel experience. While the final decision rests with the TSA officer, it's important to know what items are generally permitted and which ones are prohibited. So, what should you bring in your airport backpack?

Liquids, electronics, and powders

Liquids

The Transportation Security Administration (TSA) has specific guidelines for liquids, aerosols, and gels, collectively referred to as the 3-1-1 liquids rule. You are allowed to bring a quart-sized bag of liquids in your carry-on. This includes liquids, aerosols, gels, creams, and pastes. Each liquid item must be in a container of 3.4 ounces (100 milliliters) or less. This facilitates the screening process and ensures ease of passage through the checkpoint. Any liquid not meeting these requirements will require additional screening and may not be permitted in your carry-on.

Electronics

When packing electronics in your backpack for airport security, it is recommended to place them in a separate layer for ease of screening. Additionally, consider taping a card with your name and contact information to your electronic devices. This helps identify your devices and ensures they can be returned to you if needed.

Powders

As of June 30, 2018, the TSA implemented new rules for powder-based substances in carry-on baggage for flights departing to the United States. Powder-like substances over 12 ounces (350 milliliters) may require additional screening. If the powders cannot be resolved at the central checkpoint, they will not be permitted in the cabin and will be disposed of. It is recommended to place powders in checked baggage to avoid any issues.

Travel documents

Passport:

The passport is the most important travel document. Keep it easily accessible as you will need it at airport security, when boarding the plane, and when filling out entry forms. Some countries, like the United Kingdom, require you to inform them about the passport you plan to use for travel in advance. Additionally, ensure your passport details are up-to-date if you are using an eVisa. If you are a US citizen, consider using the "mobile passport" app from US Customs and Border Protection for a smoother re-entry process.

Other Forms of Identification:

In addition to your passport, bring multiple forms of identification or at least copies of them. This could include a driver's license, state photo identity card, or birth certificate. Adult passengers (18 and older) are required to show valid identification at the airport checkpoint. Starting May 7, 2025, ensure that your state-issued ID or license is REAL ID-compliant for flying within the US.

Visa and Travel Authorizations:

Research the visa requirements for your destination country. Some countries, like Canada, may only require a valid passport for US citizens, while others may need an Electronic Travel Authorization (eTA) or a visa. For example, the UK requires an ETA for short stays of up to 6 months, and New Zealand requires an NZeTA for permanent residents of Australia or travellers from visa waiver countries.

Health Requirements:

Some countries have specific health requirements for entry. For example, Cuba requires visitors to have a visa and health insurance. Keep in mind that due to the COVID-19 pandemic, some destinations may also require proof of vaccination or a negative COVID-19 test within a specified timeframe.

Travel Insurance Information:

Keep your travel insurance information easily accessible. Most travel insurance companies offer mobile apps that can store your plan information and provide quick access to starting the claims process. Having a digital or hard copy of your insurance details is beneficial if you need to make a claim during your trip.

Itinerary and Proof of Purchase:

Carry copies of your itinerary, flight bookings, and hotel reservations in your backpack. This helps in case there are any issues with your reservations when you arrive. It is also a good idea to have proof of purchase or tickets for any events or activities you have booked during your trip.

Customs and Immigration Declarations:

Some countries, like Canada, allow you to complete your customs and immigration declaration in advance using an app or online platform. This can simplify your arrival process and save you time at the airport.

Remember to keep your travel documents organized and easily accessible in your backpack. It is also a good idea to make digital copies of your essential documents and leave them with a trusted contact who can help if you need access to them while abroad.

In-flight entertainment

Electronic Devices

It is essential to pack your favourite electronic devices, such as a laptop, tablet, or e-reader, to keep yourself entertained. Download movies, TV shows, books, or games beforehand so that you can access them offline during your flight. Make sure your devices are fully charged before your flight, and consider investing in a portable power bank to ensure your devices stay charged throughout your journey. Additionally, don't forget to bring your headphones for a more immersive experience.

Traditional Entertainment

If you prefer more traditional forms of entertainment, bring a book, magazine, or puzzle book. A Kindle or other e-readers are also great options as they allow you to carry multiple reading options without adding bulk to your bag.

Games and Activities

For those who enjoy interactive entertainment, consider packing a miniature colouring book and a small set of coloured pencils, or small packable games. A deck of cards or portable two-player games can also be a fun way to pass the time with a travel companion.

Comfort Items

Enhance your comfort during the flight with items such as an eye mask, earplugs, and a travel pillow, especially for long-haul flights. An eye mask can help block out light from overhead lights, seatback screens, and plane windows, while earplugs can reduce noise distractions. A travel pillow can provide much-needed neck support and make your journey more comfortable, especially if you plan to sleep during the flight.

Clothing and comfort items

For comfort items, staying hydrated is a top priority. Bring a reusable water bottle and fill it up before boarding the plane. Insulated bottles are an excellent choice as they can keep your drink cold for hours. It is also a good idea to bring your own snacks, such as fruits, protein bars, dried fruits, crackers, and chocolate, to save time and money.

To make your flight more enjoyable, pack some entertainment options. This can include a book, e-reader, tablet, magazine, or your laptop. Don't forget to fully charge your devices before leaving, and download movies or games if you wish to use them during the flight. Noise-canceling headphones or earbuds can also enhance your in-flight entertainment experience and help you relax.

For added comfort, consider bringing an eye mask and earplugs if you plan to nap during the flight. A cozy blanket, especially for family travel, can also make your journey more comfortable. Lastly, don't forget to pack your essential toiletries, such as a lip mask, moisturizer, and antibacterial lotion, to keep yourself refreshed and hydrated throughout the journey.

Snacks and medication

When it comes to snacks, solid food items are permitted in carry-on and checked baggage. However, it is important to note that only foods, powders, and other materials that can clutter bags and obstruct clear images on the X-ray machine may be instructed by TSA officers to be separated from carry-on bags. To facilitate the screening process, it is recommended to keep your carry-on bag organised and uncluttered.

As for medication, it is allowed in both carry-on and checked baggage. Nevertheless, it is highly recommended to place your medication in your carry-on bag for immediate access. While the Transportation Security Administration (TSA) does not require medication to be in prescription bottles, individual state laws regarding the labelling of prescription medication must be followed. Medication is typically screened by X-ray, but passengers can request a visual inspection instead if they do not want their medication X-rayed. This request should be made before sending any items through the X-ray machine. Additionally, medically necessary liquids, medications, and creams exceeding 3.4 ounces or 100 milliliters are permitted in carry-on bags. If your medical condition requires it, you may bring a juice box or other liquids over 3.4 ounces, but expect additional screening.
