Guide to the Perfect Flight Carry-On Luggage

Choosing the right carry-on suitcase can be a challenge. Every airline has its own rules regarding size and weight, and the vast array of models on the market doesn't make the decision any easier. This guide is designed to give you an overview of the key criteria and presents a selection of models suitable for short trips of three to five days. Our goal is to provide you with an informed basis for purchasing a functional and compliant travel companion.

What to Look for When Choosing a Carry-On Suitcase

To ensure your new cabin baggage meets requirements and makes your journey smoother, several features are particularly important.

1. Dimensions and Airline Compliance

The most common size for carry-on luggage, accepted by many major airlines, is 55 x 40 x 20 cm. A cabin trolley with these dimensions typically offers enough space for a multi-day trip. However, it is essential to check your airline's specific regulations before every flight, as they can vary. A suitcase that meets these standard dimensions minimises the risk of additional fees or the need to check your bag at the gate.

2. Material and Weight: The Advantages of a Hardshell

A hardshell carry-on offers robust protection for its contents. Materials like polycarbonate (PC) or polypropylene (PP) are not only resistant to impact but are also often surprisingly lightweight. Lightweight cabin baggage allows you to use more of your weight allowance for personal items. Hardshell suitcases are also easy to clean and reliably protect contents from moisture.

3. Functionality: TSA Lock and 4-Wheel System

Modern carry-on suitcases come with features that significantly enhance convenience.

• Trolley with a TSA Lock: An integrated TSA (Transportation Security Administration) lock is especially beneficial for travel to the USA. It allows security personnel to open and inspect the suitcase with a master key without damaging the lock.
• Suitcase with 4 Wheels: A so-called spinner suitcase with four 360° rotating wheels can be effortlessly glided alongside you and manoeuvred through narrow aisles at the airport or on a train. This reduces the strain on your arms and shoulders compared to models with only two wheels.

Frequently Asked Questions (FAQ)

What does a TSA lock on a suitcase mean?

A TSA lock is a special lock that can be opened by the U.S. Transportation Security Administration (TSA) with a master key. This allows for security checks at the airport without damaging the lock or the suitcase. For travel to the USA, a trolley with a TSA lock is highly recommended.

How big can a carry-on suitcase be?

The permissible dimensions for carry-on luggage vary by airline. A widely accepted guideline size is 55 x 40 x 20 cm. Some airlines allow slightly larger dimensions, while others (especially budget airlines) have stricter requirements. It is always advisable to check the exact regulations on the respective airline's website before your trip.

Is a hardshell or softshell carry-on better?

Both types have their advantages. A hardshell carry-on offers better protection for fragile items and is more resistant to impacts and moisture. Softshell suitcases are often more flexible and feature exterior pockets for quick access to documents or laptops. The choice depends on your personal travel habits and the contents you plan to transport.
