How to Choose the Right Carry On Travel Backpack: Our Top Recommendations for 2026

Navigating the world of air travel can be complex, especially when it comes to baggage allowances. Finding a single bag that meets ever-changing airline rules, holds all your essentials and transitions smoothly from the airport to a business meeting can feel like a challenge. A well-chosen carry on travel backpack simplifies this process, offering a versatile solution for short trips, work and daily commutes.

As the Joybuy Product Recommendation Officer, my role is to help you find practical and reliable products. This guide will walk you through the key features to consider when selecting a hand luggage backpack and present a few standout options to streamline your search.

What to Look for in a Carry On Travel Backpack

Before diving into specific products, let's outline a few essential criteria to guide your decision. Focusing on these aspects will help you find a bag that truly fits your travel style.

1. Airline Size and Weight Compliance

The most critical factor for an airplane backpack is its dimensions. In the UK and Europe, standard carry-on limits are often around 55 x 40 x 23 cm. However, budget airlines like EasyJet have stricter under-seat allowances, often requiring a 45x36x20 backpack. Always check the specific requirements of the airline you fly with most frequently. Many modern travel backpacks are designed with these dimensions in mind, and some even feature expandable compartments for greater flexibility.

2. Organisation and Accessibility

A great travel backpack keeps your belongings organised and easy to access. Look for features that suit your needs, such as:

  • Clamshell Opening: This design allows the main compartment to open flat like a suitcase, making packing and unpacking far more efficient.
  • Dedicated Laptop Compartment: A padded backpack with laptop compartment is essential for protecting your tech during transit. Ensure it’s the right size for your device.
  • Multiple Pockets: Separate pockets for passports, water bottles, cables and toiletries prevent you from having to rummage through your bag at security or on the plane.

3. Versatility and Carry Options

Your travel needs may vary from one trip to the next. A versatile cabin bag can adapt to different situations. Consider a business travel backpack that has a sleek, professional appearance. For those who want to avoid shoulder strain during long walks through the terminal, a wheeled travel backpack offers a convenient hybrid solution. Convertible straps that can be tucked away are also a useful feature, allowing the bag to be carried like a briefcase.

Our Top Recommendations for 2026

Here are a few carry on travel backpacks that offer a strong combination of functionality, organisation and travel-friendly design.


1. 40L Expandable Travel Backpack

40L Expandable Travel Backpack in Blue

Why It Stands Out: This backpack’s key feature is its adaptability. It starts at a compact 50 x 35 x 15 cm but can be expanded to 50 x 35 x 20 cm using a side zipper. This allows it to meet the carry-on requirements for a wide range of airlines while offering extra space when you need it.

The main compartment opens 90-180 degrees, which can help streamline the airport security process. It is constructed from a water-resistant polyester fabric, providing a degree of protection against light rain.

  • Pros:

    • Expandable design for flexible capacity.
    • TSA-friendly flat-opening main compartment.
    • Convertible carry system (backpack or briefcase style).
    • Luggage strap for securing to a rolling suitcase.
  • Who is it for? This is an excellent choice for frequent flyers who travel on various airlines with different baggage allowances and appreciate having flexible packing capacity.

2. Airline Compliant Backpack with USB Charging Port

Airline Compliant Backpack with USB Port in Pink

Why It Stands Out: Specifically designed with dimensions of 45 x 36 x 20 cm, this backpack is sized to fit the under-seat allowance for airlines like EasyJet. Its standout feature is the integrated USB charging port, which allows you to connect your own power bank internally and charge devices on the move.

The full 180-degree clamshell opening simplifies packing, while dedicated compartments for a 15.6-inch laptop and even a separate section for shoes make it a highly organised option. This is a practical travel backpack for women and men alike, available in multiple colours.

  • Pros:

    • Sized to meet specific budget airline requirements.
    • External USB port for convenient device charging (power bank not included).
    • Suitcase-style 180-degree opening for easy packing.
    • Includes a separate shoe compartment and waterproof pockets.
  • Who is it for? Ideal for students, commuters and travellers who frequently fly on budget airlines and want a bag that maximises their free baggage allowance while keeping tech charged.

3. Travel Backpack with Wheels

Travel Backpack with Wheels in Black

Why It Stands Out: This bag offers the best of both worlds: the portability of a backpack and the convenience of a wheeled trolley. It’s a true 2-in-1 design, featuring tuck-away shoulder straps and a sturdy telescoping handle with smooth-rolling rubber wheels.

With a generous 36L capacity and a dedicated compartment for laptops up to 17 inches, it’s well-suited for carrying heavier loads. The construction includes heavy-duty, water-resistant fabric and a reinforced bottom panel, making it a durable choice for frequent use.

  • Pros:

    • Convertible design functions as a backpack or a wheeled trolley.
    • Large, padded compartment fits laptops up to 17 inches.
    • Durable, water-resistant construction with corner guards.
    • Multiple compartments for comprehensive organisation.
  • Who is it for? This is a great fit for business professionals, university students or any traveller who wants the option to roll their luggage through airports and train stations to avoid carrying weight on their back.

Frequently Asked Questions

What is a good size for a carry on backpack?

A good size for a carry on backpack generally falls within the dimensions of 55 x 40 x 23 cm, as this is accepted by many major airlines. However, for budget carriers, a smaller bag around 45 x 36 x 20 cm is often required for the free under-seat allowance. Always confirm the specific dimensions with your airline before you fly.

Can a backpack be used as a carry on bag?

Yes, a backpack is an excellent choice for a carry on bag, provided it meets the airline's size and weight restrictions. Backpacks offer great organisation and are easy to carry, making them a popular alternative to traditional rolling suitcases.

Is a 40L backpack too big for carry on?

Not necessarily. The suitability of a 40L backpack depends more on its dimensions than its volume. Many 40L backpacks are specifically designed to comply with carry-on size limits. For example, the expandable 40L backpack mentioned above fits within standard dimensions. The key is to check the length, width and depth of the bag against your airline's rules.
