Buying a Suitcase: How to Avoid the Most Common Mistakes

A broken wheel at the airport, a zipper that won't close after packing, or a crack in the shell after the first flight. Choosing a new travel suitcase can feel like a gamble. Manufacturers make big promises, but in practice, many suitcases disappoint. Before you invest in new luggage, it's wise to know the common pitfalls.

Many travelers fall for the same traps:

1. The "ultra-lightweight" myth: A lightweight suitcase is convenient, but not if it comes at the cost of durability. Extremely light materials are often thinner and can crack or dent more easily under the pressure of baggage handling.
2. Incorrect carry-on dimensions: Buying a carry-on suitcase that is just a few centimeters too large for airline regulations like those of KLM or Transavia is a classic mistake. This leads to unexpected fees at the gate.
3. Weak components: Wheels that get stuck on an uneven street or a wobbly trolley handle are common annoyances. These parts largely determine the ease of use of your trolley.

By focusing on the right specifications, you can find a model that will last for years.

Choosing the Right Suitcase: Key Specifications to Check

To avoid buyer's remorse, it's helpful to look beyond just the color and price. Three components are crucial for the quality and lifespan of your suitcase.

Material: Is a Hardside Suitcase the Right Choice?

The exterior of a hardside suitcase determines how well your belongings are protected. The two most commonly used materials are ABS and polycarbonate.

• ABS (Acrylonitrile Butadiene Styrene): This is a hard and rigid plastic. It is often cheaper, but also heavier and less flexible. ABS can crack more easily upon hard impact.
• Polycarbonate (PC): This material is more flexible and lighter than ABS. It may dent on impact but often springs back to its original shape. This makes it more resistant to the rough handling at airports. Many suitcases also use a mix of PC and ABS to strike a balance between price and durability.

Wheels: The Convenience of a Four-Wheel Spinner Trolley

Modern suitcases usually have four wheels, also known as 'spinner wheels'. These allow you to rotate the suitcase 360 degrees and roll it upright beside you, which puts much less strain on your arm and shoulder. Suitcases with two wheels must be pulled behind you. With spinner wheels, pay attention to the quality: double wheels offer more stability, and models described as 'quiet' roll more smoothly over various surfaces.

Security and Convenience: The Function of a Suitcase with a TSA Lock

A suitcase with a TSA lock is especially useful if you are traveling to the United States. The Transportation Security Administration (TSA) has the right to inspect luggage. Using a special master key, they can open a TSA lock without forcing it. If you have a different type of lock, you risk it being broken open. Even for travel outside the US, a built-in combination lock offers a secure and practical way to lock up your belongings.

Frequently Asked Questions About Suitcases

How do I set the combination lock on my suitcase?

Most suitcases with a built-in combination lock (including TSA locks) come with the default code 0-0-0. To set your own code, look for a small, often recessed button next to the number dials. Press this button with a pen, set your personal code, and then slide the opening button to confirm the new code. The exact steps may vary by brand, so consult the product information.

What is the difference between ABS and polycarbonate for a hardside suitcase?

ABS is a more rigid and often cheaper material, but it can crack under hard impact. Polycarbonate (PC) is more flexible, lighter, and more resistant to impact because it can bend and return to its original shape. For frequent air travel, a 100% polycarbonate suitcase generally offers better durability.

What size suitcase do I need for a one-week vacation?

For a one-week vacation, a medium suitcase about 60-70 cm high (approximately 50-75 liters in volume) is usually sufficient. This provides enough space for clothes, shoes, and toiletries. If you are a minimalist packer or traveling to a warm destination, you might even manage with a large carry-on suitcase of about 55 cm high (approximately 35-40 liters).
