Choosing a cabin suitcase: how to find the right one for your flight

A cabin suitcase might seem simple to choose, until you reach the gate and discover that it’s the wrong size or your bag is too heavy. Even small differences in size can matter, especially with budget airlines. Terms such as “20 inch”, “lightweight” and “airline approved” don’t always tell you how practical a suitcase will be.

Before you buy, look out for these three common pitfalls:

  1. Inch size isn’t a fixed standard. Two 20-inch suitcases can have different external dimensions. Wheels, handles and rigid frames all count.
  2. A low weight doesn’t automatically mean more packing space. Check the capacity in litres and the interior layout as well as the weight.
  3. A product claim isn’t a guarantee that every airline will accept it. Cabin baggage rules vary by airline, ticket type and route. Always check your airline’s latest requirements.

What size is a cabin suitcase?

First, check the maximum external dimensions allowed with your ticket. With Ryanair cabin baggage, for example, a small bag that fits under the seat can measure up to 40 x 20 x 25 cm. A larger cabin bag may only be allowed with an additional ticket or priority option. easyJet cabin baggage and British Airways have different combinations of dimensions and conditions.

Keep these points in mind:

  • Measure the suitcase including wheels, handles and any protruding parts.
  • Compare the product dimensions with the cabin baggage rules for your specific booking.
  • Check whether “cabin size” refers to a bag for the overhead locker or one that fits under the seat.
  • Use 20-inch suitcase as a starting point only; the exact measurements in centimetres are what matter.

A compact cabin suitcase around 53 to 56 cm tall is often suitable for short trips, but there’s no universal guarantee it will be accepted. A weekend bag or soft-sided cabin case can sometimes be easier to fit within the limit than a rigid hard-shell suitcase.

Comparing weight, capacity and materials

A lightweight suitcase leaves more of your total weight allowance for clothes and electronics. So compare the empty weight with the capacity. A soft cabin suitcase weighing 1,46 to 1,7 kg can be a practical choice if you want to take as much as possible. A hard-shell suitcase weighing 2,5 to 3,45 kg usually has a more rigid exterior, but leaves less weight allowance for your belongings.

Hard-shell or soft-sided suitcase?

A hard-shell suitcase made from ABS, ABS+PC or polycarbonate protects your belongings with a rigid shell. This can be useful for fragile items, but a hard case may be less forgiving if you’re just over the size limit.

A soft-sided suitcase made from polyester often has extra external pockets, making it handy for documents, a tablet or a boarding pass. It offers different protection from a hard shell. Check the construction: a reinforced frame or EVA panels can help the bag keep its shape, but won’t automatically make it suitable for every airline.

Wheels and compartments

Four spinner wheels turn in multiple directions and are handy at stations and on smooth airport floors. Two wheels can be lighter and take up less space, but you’ll usually need to pull the case behind you.

Also check for:

  • an adjustable telescopic handle;
  • cross straps to keep clothes in place;
  • a mesh or zipped pocket for accessories;
  • a separate front pocket for travel documents;
  • a divider to keep dry and damp items apart.

A suitcase with a TSA lock can be opened by authorised staff during security checks in certain countries without forcing the lock. It won’t prevent someone who knows the combination from opening the suitcase. Set a new code as soon as you receive it and keep the combination somewhere safe.

Frequently asked questions about cabin suitcases

Can you always take a cabin suitcase on a plane?

That depends on the airline, your ticket and the size of the suitcase. Check the latest baggage rules for Ryanair, easyJet, British Airways or the airline you’re travelling with. A suitcase that counts as cabin baggage with one airline may only be allowed with another for an additional fee.

Is a hard-shell or soft-sided suitcase better for a weekend away?

A soft-sided suitcase often has external pockets and is relatively lightweight. A hard-shell suitcase keeps its shape and can protect the contents better from external pressure. For a weekend case, the most important things to consider are its empty weight, capacity in litres and exact external dimensions.

How long does a cabin suitcase last?

Its lifespan depends on how often and how heavily you use it, the surfaces you take it over and how well you maintain it. Don’t overload the handle or wheels, avoid dragging the suitcase over rough paving unnecessarily and clean the exterior according to the product instructions. When buying, also check the warranty information and your statutory consumer rights in the EU.
