Packing a good carry-on isn’t about stuffing your backpack with every travel gadget you own. It is about keeping the things you truly need safe, organized, and easy to reach during the flight.

After years of traveling with my family, I have developed a system that keeps me surprisingly organized on airplanes—even though organization does not always come naturally to me! I use a small Fjällräven Kånken backpack and give everything a specific place. My passport stays in the front pocket, medication and electronics remain safely inside the main compartment, and one small pouch holds everything I need once I am seated.

This carry-on essentials list includes the items I personally use, along with practical advice for deciding what deserves space in your own bag. You may not need every item I carry, but the goal is the same: keep important belongings with you and avoid digging through an overstuffed backpack every twenty minutes.

Carry-On vs. Personal Item: What Is the Difference?

A carry-on suitcase generally goes into the overhead bin, while a smaller personal item fits underneath the seat in front of you. Airlines may treat them as two separate pieces of luggage, but both are belongings you carry onto the airplane.

The essentials I want during the flight stay in my personal-item backpack rather than my overhead suitcase. This keeps my medication, passport, electronics, food, and comfort items within reach—and prevents me from opening the overhead bin every time I need something.

How I Pack My Personal Item Perfectly After Years of Flying

I am not naturally the most organized person, but my airplane personal item is an exception. After taking countless flights, I have figured out exactly where everything belongs and which items I actually need during the flight.

I use a Fjällräven Kånken backpack because it is small enough to carry comfortably but large enough to hold my medication, electronics, food, water bottle, sweater, and compression socks. I don’t fill it with “just in case” items that I am unlikely to use. Everything inside has a purpose and a designated place.

The small front pocket holds my passport so I can reach it quickly without opening the entire backpack. My medication, laptop, and iPad stay protected inside the main compartment. The items I might need before or after the flight—such as my sweater, compression socks, beef jerky, and water bottle—are packed where I can reach them without completely unpacking the bag.

My best trick is using one small in-flight pouch. It contains everything I am likely to need once I sit down, including my AirPods, Bluetooth airplane adapter, phone charger, lip balm, tissues, and gum. I remove that one pouch before placing my backpack under the seat and put it into the seat-back pocket. That way, I am not constantly bending down and digging through my bag during the flight.

The key is to pack according to when you will need each item. Keep documents accessible, protect medication and electronics inside the bag, and place everything you will use during the flight into one removable pouch. It is a simple system, but it makes flying considerably easier.

 

 

Documents and Medication

The first things in your carry-on should be the items that would be difficult—or impossible—to replace after you leave home. Entertainment and comfort items are helpful, but your identification and medication are the real essentials.

1. Passport or Identification

Your passport or identification needs to be secure but easy to reach. You will need it several times between arriving at the airport and boarding the plane, so burying it at the bottom of your bag creates unnecessary stress.

I carry a Fjällräven Kånken backpack, and its small front pocket is the perfect size for my passport. I always put it in the same place, which means I never have to search through my backpack while standing in a security or boarding line.

2. Prescription Medication

Never pack essential medication where you could become separated from it. I learned this the hard way in Scotland when I discovered that I had not brought enough of a medication I need. We lost an entire vacation day visiting an emergency room and trying to navigate treatment with American health insurance.

Now, I carry a pill container that holds enough medication for trips of up to three weeks. It stays in the main compartment of my backpack and remains with me throughout the journey. Medication is one of the few things I double-check before leaving for the airport.

Food and Hydration

Food and drinks sold at airports can be expensive, and the snack served during a flight may not be enough to keep you satisfied. I always pack one filling snack and a water bottle that is small enough to fit comfortably inside my backpack.

3. A Filling Snack

I usually bring a bag of beef jerky. It contains plenty of protein, takes up very little room, and doesn’t crumble or become smashed inside my backpack. More importantly, it keeps me from becoming desperately hungry if the flight is delayed or the onboard food is unappealing.

Whatever snack you choose, look for something filling, easy to pack, and unlikely to leak. Protein bars, nuts, crackers, or dried fruit can also work well.

4. A Small Reusable Water Bottle

Full-sized water bottles take up too much space in my small backpack, so I carry a kid-sized Owala bottle. It holds enough water for the flight without dominating the entire bag.

I take it through airport security empty and fill it before boarding. A smaller bottle may require an extra refill, but I would rather do that than carry a bulky bottle that leaves no room for anything else.

My In-Flight Pouch

The best part of my packing system is a small pouch containing everything I might need while sitting in my seat. I remove it before placing my backpack under the seat and put the pouch into the seat-back pocket.

This prevents me from repeatedly bending down, pulling out my backpack, and searching through it during the flight.

5. A Small Zippered Pouch

The pouch itself is an essential part of my system. It keeps small objects from disappearing into the bottom of my backpack and gives me one thing to grab when I sit down.

Choose something small enough to fit inside the seat-back pocket without taking up all the available space.

6. Phone Charger With a USB-A Connection

I pack a phone charger with the larger, traditional USB-A connection. Many airplanes still have USB-A charging ports rather than the smaller USB-C ports used by newer devices.

Charging options vary considerably between planes, but carrying the correct cord gives me the best chance of being able to charge my phone during the flight.

7. Bluetooth Airplane Adapter

My Bluetooth airplane adapter plugs into the seat-back entertainment system and sends the sound to my AirPods. It means I don’t have to use the disposable airline headphones or carry a second pair with a cord.

This is one of those small gadgets that sounded unnecessary until I tried it. Now it always goes into my in-flight pouch.

8. AirPods

I use my AirPods for the airplane entertainment system, my downloaded movies, music, and anything I watch on my iPad. They take up almost no space and are much easier to pack than large headphones.

9. Lip Balm

Airplane cabins can feel incredibly dry, so lip balm is one of the small comfort items I actually use. Keeping it in the pouch prevents it from becoming lost at the bottom of my backpack.

10. Tissues

A small travel pack of tissues is useful for spills, runny noses, and bathrooms that have somehow run out of toilet paper. Someone in my family always ends up needing one.

11. Gum

I carry gum to help with ear pressure during takeoff and landing. It also helps me feel a little fresher after spending hours on a plane. Also my breath is awful after sitting on a dry plane for so long!

Comfort Items for the Flight

Airplane temperatures are unpredictable, and even a pleasant flight can become miserable when you are cold or uncomfortable. I don’t carry a large blanket or travel pillow, but I always make room for two comfort items that I actually use.

12. A Sweater

I carry a sweater even when I am traveling somewhere warm. Airplane cabins can become surprisingly cold, and the thin blankets offered on some long flights are not always enough.

A sweater is also useful after landing if the weather is cooler than expected. I choose one that is warm but still flexible enough to fit inside my backpack. I was recently on a Breeze flight to Phoenix and it was so cold that I had my hoodie tied around my face and I was still freezing! Take something warm!

13. Compression Socks

Compression socks always go into my personal item, particularly for a long flight. They take up very little space and make my legs feel much better after sitting for hours.

Keep them somewhere accessible so you don’t have to unpack your entire bag when you are ready to put them on. If you have a medical condition or circulation concerns, ask your healthcare provider whether compression socks are appropriate for you.

Tip: Put them on while you are the airport and before you get on your flight. I have had to do some major contortioning to get them on in flight!

14. J-Pillow Travel Pillow

I bring my J-Pillow on long flights. It supports my head, neck, and chin better than a traditional U-shaped travel pillow, which makes it easier for me to rest without my head constantly falling forward. It works best with a window seat tha tyou can lean on.

The pillow would take up too much room inside my small backpack, so I snap it to the outside of my personal item. It remains easy to carry through the airport without using any of the valuable space inside my bag.
