Carry-On Suitcase Buyer's Guide: How to Choose the Right Model

Choosing the right carry-on suitcase can make a major difference to the efficiency and comfort of your journey. With ever-changing airline baggage policies and a vast array of models on the market, it can be challenging to keep track. The goal of this guide is to provide you with objective orientation and highlight the features that are crucial for making an informed decision. We will introduce you to various models tailored to different travel needs.

What to Look for When Choosing a Carry-On Suitcase

To find the perfect model, it helps to be familiar with a few fundamental criteria. These factors determine not only the durability of your luggage but also its handling and compliance with airline regulations.

Material: Choosing Between Polycarbonate, ABS, and Polypropylene

A hard-shell suitcase offers superior protection for its contents. The most common materials have distinct properties:

• Polycarbonate (PC): This material is known for its flexibility and impact resistance. It can absorb shocks by deforming slightly and then returning to its original shape.
• Acrylonitrile Butadiene Styrene (ABS): ABS is a lighter and often more cost-effective material. It is rigid and scratch-resistant but less flexible than polycarbonate. Many suitcases combine ABS with a PC layer to achieve a balance of lightness and durability.
• Polypropylene (PP): PP is extremely robust and resilient, even at low temperatures. It is also very light, making it an excellent choice for a lightweight suitcase.

Mobility and Security: The Importance of 4 Wheels and a TSA Lock

A suitcase's manoeuvrability is critical in a busy airport terminal. A suitcase with 4 wheels, also known as spinner wheels, can rotate 360° and be pushed effortlessly alongside you, making it easier to navigate through narrow aisles.

A trolley with a TSA lock is important for travel to the USA and several other countries. This special lock allows security authorities (like the U.S. Transportation Security Administration) to open the luggage with a master key if necessary, without damaging the lock.

Dimensions and Weight: Airline Compliance

The permitted dimensions for cabin baggage vary by airline. The IATA (International Air Transport Association) recommends a size of 55 x 35 x 20 cm, but many airlines, especially low-cost carriers, have stricter requirements. It is therefore essential to check the specific regulations of your airline before you travel. A lightweight cabin trolley offers the advantage of allowing more weight for your belongings without exceeding the baggage allowance.

Frequently Asked Questions (FAQ)

How large and heavy can a carry-on suitcase be?

There is no universal rule. Most airlines follow a size guideline around 55 x 40 x 23 cm and a weight limit between 8 and 10 kg. However, these figures can vary significantly. It is essential to check your airline's exact regulations before every flight to avoid extra fees.

What is the advantage of a hard-shell suitcase for carry-on?

A hard-shell suitcase offers better protection for fragile items and is generally more water-resistant than a soft-shell suitcase. Soft-shell suitcases, on the other hand, are often more flexible and feature external pockets for quick access to travel documents. The choice depends on whether you prioritise protection or flexibility.

Is a TSA lock necessary for every flight?

A trolley with a TSA lock is not mandatory for every flight. Its primary function is to facilitate security checks in the USA (and some other countries) without the lock having to be broken. However, it also offers a security advantage over a simple lock on other journeys.
