Travel light, travel smart: How to choose the best carry-on suitcase

Master the art of choosing the right carry-on suitcase. This guide explores size, material, features, and more to help you travel smarter and lighter.

Whether you're a seasoned traveller or preparing for your first international flight, finding the perfect carry-on suitcase can significantly enhance your journey. From breezing through airport security to navigating cobblestone streets, your suitcase becomes an extension of your travel style. But with so many options on the market—ranging from sleek aluminum hardshells to soft-sided bags that flex to fit—how do you choose the one that's right for you?

This comprehensive guide walks you through all the essential features to consider when choosing a carry-on: from size and airline restrictions to durability, organization, and even aesthetics. With a bit of insight and planning, you’ll discover how the right carry-on can offer freedom, efficiency, and a more enjoyable travel experience. Let’s unpack what makes a suitcase not just a bag, but a reliable travel companion.

Size matters: Domestic vs. international

One of the most crucial factors when choosing a carry-on suitcase is understanding airline size regulations. A few inches can be the difference between success in the overhead bin and a last-minute gate check.

Domestic flights—particularly in North America—tend to allow slightly larger dimensions than international carriers. Airlines enforce different size limits depending on your destination:

• Domestic flights (e.g., within Canada or the United States) often allow larger carry-ons, typically measuring around 22 x 14 x 9 inches.
• International flights (especially on budget airlines) are stricter, with common limits of 21 x 13 x 7 inches.

Here’s a quick comparison:

These size guidelines include handles and wheels. If you frequently travel internationally, it’s smarter to err on the side of caution and choose a more compact carry-on that meets stricter requirements.

Key tips:

• Always check airline-specific restrictions before you fly.
• If flying multiple airlines on one itinerary, choose luggage that complies with the strictest standard.
• Don’t forget weight limits—especially on budget airlines.

Airline restrictions: Know before you go

Airlines differ not only in size allowances but also in weight restrictions. Some carriers are notoriously strict and will weigh your carry-on at the gate. Always check your airline’s specific rules before purchasing. Key considerations:

• Weight limits: Some airlines impose strict weight restrictions (e.g., 7–10 kg).
• Measurements include wheels and handles: A bag that fits when empty might exceed limits when packed.
• Budget airlines: Carriers like Ryanair or Spirit often have smaller allowances.

Here’s how to stay compliant:

• Use a digital luggage scale at home.
• Opt for lightweight suitcases to maximize packing capacity.
• Measure your bag, including handles and wheels.

Being prepared saves you from last-minute repacking chaos at the airport—and potential fees.

Material choices: Balancing durability and weight

When choosing the perfect carry-on, the exterior material is more than just an aesthetic preference—it directly affects the suitcase’s durability, weight, and performance in real-world travel scenarios. Whether you’re squeezing into overhead compartments, braving unpredictable weather, or packing delicate items, the right material can offer peace of mind and practicality.

Suitcases generally fall into two main categories: hard-shell and soft-shell. Each has its own set of advantages, depending on your travel style and priorities. Hard-shell luggage offers a sleek, protective barrier for your belongings, while soft-shell options tend to be more flexible and forgiving, especially when space is tight or you need extra compartments. Here's how they compare:

Hard shell vs. Soft shell

• Hard shell (Polycarbonate/ABS/Aluminum):

  • Superior protection against impacts and weather.
  • Sleek, modern look, but can show scratches.
  • Ideal for fragile items or environments with high humidity.

• Soft shell (Nylon/Polyester):

  • Lightweight and flexible, often with expandable compartments.
  • External pockets for easy access to documents or snacks.
  • Less protection for delicate items.

Durability and weight comparison

Tip: Frequent travellers might prefer hard shells for durability, while backpackers or minimalists may prioritize lightweight soft shells.

Wheels and handles: Smooth mobility

A suitcase’s mobility can make or break your travel experience. While sleek aesthetics and smart compartments are essential, your ability to glide smoothly through airports, cobblestone streets, or packed train stations depends heavily on the quality of the wheels and handle. Not all luggage is built for all terrain, and understanding the pros and cons of different designs will help you choose a carry-on that performs well wherever your journey takes you.

Types of wheels

• Spinner wheels (4-wheel):

  • 360-degree rotation for easy maneuvering.
  • Best for smooth surfaces like airports.

• Inline wheels (2-wheel):

  • More durable for rough terrain.
  • Requires tilting to pull, which can strain the arm.

Telescoping handles

Look for:

• Adjustable height for comfort.
• Sturdy materials like aluminum.
• Comfortable grips to reduce hand fatigue.

Pro Tip: Test the handle’s wobble—cheap models often have shaky handles that break over time.

Storage and organization

Smart interior design can significantly elevate your travel experience by keeping your belongings neatly organized and easily accessible. When selecting a carry-on, consider whether the main compartment is spacious enough and offers quick access to your essentials. Integrated mesh pockets are beneficial for storing smaller items, such as socks, chargers, or toiletries, keeping them separated and within easy reach.

Zippered sections provide secure storage for important documents or valuables, while dedicated laptop compartments are indispensable for business travellers who need to protect their devices. Compression straps also play a crucial role by securing your clothes in place and minimizing wrinkles during transit.

Some carry-ons feature expandable sections with zippered panels, offering extra space when needed; however, it’s important to note that this added room can sometimes cause your bag to exceed airline size restrictions. Choosing a suitcase that balances all these features will help streamline your packing and keep everything in its place.

Your perfect carry-on awaits

The best carry-on suitcase aligns with your travel habits, budget, and personal style. Prioritize airline compliance, durability, and ease of use—whether that means spinner wheels for seamless airport gliding or a lightweight nylon design for backpacking trips.

Whether you're exploring a new continent, dashing through an airport, or embarking on a weekend getaway, the right suitcase offers reliability and convenience that helps you focus on what truly matters: the journey ahead.

Choose wisely, and your carry-on will be more than luggage—it’ll be your trusted travel ally for years to come.
