Choosing the best backpack for air travel requires balancing internal storage capacity with the strict dimension requirements set by global airlines. Carrying a single bag allows you to skip the baggage carousel and move through the airport with greater speed and mobility. This guide explains the technical specifications you need to know and recommends top bags for your next flight.
What size backpack can you carry on an airplane?
Most major domestic and international airlines allow carry on bags that do not exceed 22 by 14 by 9 inches. These dimensions include handles and wheels if your bag has them. If your backpack exceeds these measurements, you may be forced to check the bag at the gate, which often incurs additional fees. It is important to check the specific requirements of your airline because budget carriers often have smaller limits, sometimes as restrictive as 18 by 14 by 8 inches for personal items.
A personal item must fit entirely under the seat in front of you. While a standard carry on goes in the overhead bin, the personal item is usually a smaller backpack or laptop bag. For those looking for a compact solution that fits these smaller requirements, the Hoodie Backpack at $79 is a versatile choice for short trips or daily use.

Is a 40L backpack ok as a carry on?
A 40 liter backpack is generally the maximum size allowed for carry on travel, but volume alone does not guarantee acceptance. The physical dimensions of the bag matter more than the liter capacity. A 40L bag that is long and thin might exceed the 22 inch height limit, while a boxier 40L bag might fit perfectly. When a bag is fully packed, it can bulge and expand beyond its rated dimensions, so using internal compression straps is vital to stay within airline limits.
According to FAA regulations, all carry on items must be stowed securely during takeoff and landing. If a 40L bag is too large for the overhead compartment, flight attendants will require it to be checked. Many travelers prefer 35L to 40L bags because they provide enough space for a week of clothing without the bulk of a traditional suitcase. For travelers who need organized storage within these limits, the Luhxe Travel Bag 2.0 offers a structured design priced at $179.
What is a TSA friendly backpack?
A TSA friendly backpack is designed to speed up the security screening process by allowing you to keep your laptop inside the bag. These bags feature a dedicated laptop compartment that unzips and lies flat on the conveyor belt. This allows the X ray machine to get a clear image of the computer without other items obstructing the view. According to TSA screening guidelines, if a bag is not specifically designed to lie flat, the laptop must be removed and placed in a separate bin.
Beyond the laptop compartment, a good travel bag should have easy access pockets for liquids and electronics. This ensures you are not digging through your main compartment while standing in the security line. For those who prioritize organization, exploring specialized bags for the organized traveler can help you find a layout that fits your specific tech and accessory needs.
Essential features for the best backpack for air travel
The best backpack for air travel must offer more than just storage space. It needs to provide comfort for long walks through terminals and security for your belongings. Look for these specific features when evaluating a new bag:
- Clamshell Opening: This allows the bag to open like a suitcase, making it easier to pack and organize compared to a top loading bag.
- Stowable Straps: When you need to place your bag in a tight overhead bin or check it, being able to tuck the shoulder straps away prevents them from getting snagged.
- External Water Bottle Pocket: Staying hydrated is essential during flights, and an accessible pocket saves you from opening your main compartment.
- Load Lifters and Hip Belts: For bags over 35L, these features help distribute the weight from your shoulders to your hips, reducing fatigue.

How to measure your backpack for flight compliance
To ensure your bag fits the airline's sizing bin, you must measure it when it is fully packed. Use a tape measure to check the height from the bottom of the bag to the top of the handle. Check the width across the widest part of the back panel. Finally, check the depth by measuring how far the bag sticks out from your back. If the bag is overstuffed, use the compression straps to pull the material tight and reduce the depth.
Many modern airports now use digital scanners to check bag sizes. These machines take a 3D image of your bag and can detect if any part of it exceeds the limit. If you are close to the limit, avoid putting bulky items in the front pockets, as this is the most common reason a bag fails the size test. Instead, distribute heavy and bulky items toward the center of the bag near the back panel.
Maximizing space in your carry on backpack
Packing efficiently is the key to traveling with just a backpack. Use packing cubes to group similar items together and compress your clothing. This not only saves space but also keeps your bag organized so you can find what you need without unpacking everything. Roll your clothes instead of folding them to minimize wrinkles and fill small gaps in the bag.
Wear your largest items on the plane. If you are traveling with a heavy jacket or boots, wearing them during the flight frees up significant space in your backpack. Utilize every small pocket for chargers, cables, and toiletries. By following these methods, even a smaller bag like the Hoodie Backpack can hold enough gear for a multi day excursion.
