Choosing a cabin case for hand luggage: how to compare size, weight and features

A cabin case for hand luggage might seem easy to choose at first. But problems often only arise at the airport. Your case may turn out to be too large for the permitted dimensions, its empty weight may take up a large share of your baggage allowance, or its wheels may be less practical than you expected.

For travellers from the Netherlands, these are the three main pitfalls to watch out for:

  • Looking only at “20 inches”: a 20-inch case can have different external dimensions depending on the model. Airlines generally check the actual dimensions, including wheels and handles.
  • Confusing “lightweight” with a low net weight: always check the weight in kilograms. A hard-shell cabin case weighing 2.8 kg leaves less room for clothes than a model weighing around 1.5 kg.
  • Assuming airline compatibility is guaranteed: Ryanair, easyJet, British Airways and other airlines may have different dimensions and conditions for different ticket types. Check the current baggage rules before you travel.

Which specifications matter most?

1. External dimensions and permitted baggage

Don’t just measure the case body. The relevant measurement is usually the total external size of the cabin case, including wheels, handles and any protruding parts.

For example, a small Ryanair hand luggage case that goes under the seat needs to be considerably more compact than a trolley case you can put in the overhead locker with priority boarding. A bag measuring 40 × 20 × 25 cm is a different type of luggage from a 20-inch case that is around 55 cm high.

Keep these points in mind:

  1. Note the height, width and depth separately.
  2. Check whether the stated dimensions include the wheels.
  3. Compare the dimensions with your ticket, not just the airline’s general information.
  4. Bear in mind that your case will be full. Soft-shell models may give a little, but don’t assume they will.

2. Weight, capacity and ease of packing

A lightweight cabin case is especially useful when your airline has a strict weight limit. A model weighing 1.46 to 1.7 kg, such as the soft-shell Kono, leaves more room for clothes on paper than a hard-shell case weighing 3.45 kg.

Capacity is often given in litres, but how practical the case is also depends on its layout:

  • 30–33 litres: suitable for an overnight stay, a weekend or a compact business trip.
  • 36–39 litres: suitable for several days if you pack efficiently.
  • A fully opening front panel makes it easier to stack and organise your belongings.
  • Internal packing straps and a zipped pocket keep clothes and accessories in place.

Bear in mind that the stated capacity may only be a guide. The shape of the shell, the lining and the internal compartments all affect how much you can actually take.

3. Material, wheels and lock

A hard-shell cabin case made from ABS, ABS+PC or PC provides a sturdy outer shell around your belongings. PC is a commonly used material in the product descriptions for NINETYGO models. However, a hard shell isn’t automatically lighter or more practical.

A soft-shell cabin case, made from materials such as 600D polyester, can offer benefits such as:

  • a lower empty weight;
  • a front pocket for your passport, laptop or boarding pass;
  • flexible storage when the case isn’t in use.

Also consider the type of wheels. A case with spinner wheels has four swivel wheels and can be pushed in several directions. This is useful in a busy station or at Schiphol Airport. A two-wheeled hand luggage trolley often rolls steadily behind you and may weigh less, but you’ll need to tilt it more often when turning.

A case with a TSA lock can be opened with a special key during certain security checks. The lock won’t prevent someone from opening the case if they know the combination. So change the default code straight away and keep your new combination somewhere safe.

Frequently asked questions about cabin cases

Is a 20-inch case suitable for every airline?

No. A 20-inch case doesn’t have a fixed international external size. Check the height, width and depth of the model you’ve chosen and compare them with the conditions for your ticket. A bag that goes under the seat in front of you is often smaller than a trolley case intended for the overhead locker.

Is a hard-shell or soft-shell cabin case more practical?

It depends on how you’ll use it. A hard-shell cabin case has a fixed shape and a structured interior. A soft-shell cabin case is often lighter and has front pockets that are easier to access. A front pocket can be useful for a laptop, documents and short business trips, while a hard shell may be preferable for fragile belongings.

How long does a hand luggage case last?

Its lifespan depends on how heavily it’s used, the surfaces it’s rolled over, how much it’s packed with and how it’s handled in transit. Don’t overload the handle or wheels, avoid dragging the case over rough paving for long periods and clean the outside with a soft cloth. Before buying, also check the warranty conditions and the seller’s contact details.
