A cabin suitcase can help reduce hold-luggage fees and make your journey through the airport easier. However, its size, weight and features must match the airline you are travelling with. Many unsuitable purchases are not caused by missing features, but by unclear dimensions, impractical interior layouts or excessive empty weight.
This buying guide explains what travellers in Germany should look out for before making a purchase and which model could suit a short break, business trip or flight with Ryanair.
The term cabin suitcase does not refer to a standard size. Depending on its design, wheels and handles, a 20-inch suitcase can have different external dimensions. The permitted size for free cabin baggage also varies between airlines.
Before buying, you should therefore:
For example, a cabin suitcase for Ryanair may not need to meet the same requirements as a cabin bag on another airline.
A large capacity is only useful if you do not exceed the permitted total weight. A heavy hard-shell suitcase leaves less room for clothing, electronics and shoes. For short trips, the combination of empty weight, capacity and packed dimensions is therefore crucial.
“360° wheels” make manoeuvring easier, but the number, design and attachment method also matter. Double-spinner wheels can roll smoothly across flat airport floors. On cobblestones or uneven paths, however, you should still expect greater rolling resistance.
When choosing a handle, it is worth checking for:
The term 20-inch suitcase only describes a size category. Airlines usually consider the specific combination of height, width and depth. A model measuring 55.88 × 35.56 × 22.86 cm should be assessed differently from a suitcase measuring 56.5 × 38 × 23 cm.
If you are unsure, measure the suitcase when fully closed, including:
A hard-shell suitcase made from PC or PC+ABS has a firm outer shape and can accommodate delicate items in an organised way. The NINETYGO models featured here use interior compartments, X-shaped packing straps and zipped sections to help keep everything organised.
A soft under-seat travel bag made from Oxford fabric is more flexible and usually lighter. It may fit under the seat more easily, but does not protect the contents from pressure in the same way as a hard shell. Its suitability depends on what you are packing and the fare you have booked.
A suitcase with a TSA lock can be more convenient during security checks in countries that use the relevant procedures. However, the lock is no substitute for checking your luggage carefully and does not protect against every possible form of access.
Useful features include:

The technical specifications state dimensions of 56 × 38.5 × 23 cm and provide load ratings for the zip. Compatibility with the relevant airline must still be checked individually.

This depends on the airline, the fare you have booked and the type of baggage. Always check the external dimensions, including wheels and handles. Under-seat baggage is usually smaller than a suitcase stored in the overhead compartment.
For personal belongings on a short flight, 14 litres may be sufficient. For a weekend trip with additional clothing, 20 litres in a bag or around 38 litres in a cabin suitcase can serve as a useful guide. The actual packing capacity depends on your clothing, shoes and the interior layout.
A hard-shell suitcase offers a firm shape, wheels and often greater protection for its contents. An under-seat travel bag is lighter, more flexible and easy to access. The key factors are your flight fare, what you are packing, how you want to carry it and the permitted dimensions.
