Step-by-Step Instructions
- 1. First, let’s talk about liquid essentials. I never pack my full-size toiletries in my carry-on, and I recommend you don’t either. Instead, decant your favorites into travel-sized containers to save space and avoid any potential issues with security.
- 2. Next up, it’s time to consider your electronic devices. While it’s tempting to pack your laptop, tablet, and portable charger in your carry-on, I advise against packing irreplaceable items like your favorite portable hard drive or expensive smartwatch. If you must bring them, make sure they’re fully protected in a sturdy case.
- 3. Now, let’s think about sharp objects. As a flight attendant, I’ve seen my fair share of confiscated scissors, nail clippers, and pocket knives. To avoid any drama at security, it’s best to pack these items in your checked luggage or check with your airline for their specific policies on sharp objects in carry-ons.
- 4. When it comes to valuables, I always err on the side of caution. I never pack cash or jewelry in my carry-on, and I recommend you do the same. Instead, consider using a money belt or a secure wallet to keep your valuables close to you.
- 5. It’s also important to consider perishable items. If you’re planning to bring snacks or fresh fruit on board, be sure to check with your airline for their policies on food and drink. Some items may be prohibited, and you don’t want to get stuck with a bag of confiscated goodies.
- 6. Another thing to keep in mind is restricted materials. Certain items like flammable liquids, chemicals, or sprays are strictly prohibited in carry-ons. Familiarize yourself with the Transportation Security Administration’s (TSA) list of restricted items to avoid any issues at security checkpoints.
- 7. Finally, let’s talk about bulky items. I never pack my bulky winter coat or hiking boots in my carry-on, as they take up too much space and can be a real hassle to deal with during security screening. Instead, consider wearing your bulkiest items on the plane or packing them in your checked luggage to save space in your carry-on.
What Not to Pack

As I’ve learned from my time as cabin crew, it’s essential to be mindful of restricted items in carry on bags. These can range from the obvious, like scissors and knives, to the less apparent, such as certain types of batteries. When packing, I always double-check the airline’s list of prohibited items to avoid any issues during security checks.
Packing smart is also about considering airline carry on size restrictions. Each airline has its own rules, and exceeding these limits can result in your carry-on being checked, which may lead to delays or even damage to your belongings. I’ve seen it happen to many passengers, and it’s easily avoidable with a bit of planning.
For international flights, packing essentials like adapters, converters, and a portable charger can be a lifesaver. However, it’s crucial to pack these items correctly, especially electronic devices in carry on luggage, to ensure they are protected and easily accessible during security screenings.
Packing Essentials to Ditch
Now that we’ve covered the restricted items, let’s talk about the packing essentials you can actually ditch. I used to swear by packing my favorite hair straightener, but honestly, it’s just extra weight. Most hotels have hair dryers and irons, and if you’re really in a pinch, you can always use a hair tie or bobby pins to keep your hair looking decent.
I’ve also learned to skip packing full-size toiletries. Not only are they heavy, but they’re also a hassle to deal with at security checkpoints. Opt for travel-sized essentials or decant your favorites into smaller containers instead. Trust me, your back (and the TSA) will thank you!
Restricted Items to Avoid
As a flight attendant, I’ve seen my fair share of security scares due to restricted items in carry-ons. To avoid any hassle, it’s best to leave certain things behind. I never pack sharp objects, like scissors or knives, and I always check the airline’s policy on tools like screwdrivers. Liquids, aerosols, and gels are also a no-go in large quantities – I’ve learned to decant my essentials into travel-sized containers to avoid any issues.
It’s also a good idea to check the TSA’s website for their list of prohibited items, which includes things like fireworks, flammable liquids, and even certain types of batteries. I like to think of it as better safe than sorry – if you’re unsure about an item, it’s best to pack it in your checked luggage or leave it at home altogether.
