Buying travel luggage: how to choose a suitcase, rucksack or travel bag to suit your trip

Buying a suitable bag or suitcase sounds simple, until you find yourself at the airport with an oversized cabin suitcase, a trolley with poor-quality wheels or a laptop rucksack that becomes uncomfortable after a few days. If you are planning to buy travel luggage, it is therefore wise to look beyond colour and price.

Three common pitfalls deserve extra attention:

  1. Confusing dimensions with permitted cabin baggage. An 18- or 20-inch suitcase will not automatically comply with every airline’s rules. Airlines set their own maximum length, width, height and weight requirements.
  2. Overestimating capacity. A high litre capacity does not tell you everything. The layout, zip opening and shape determine how much clothing and how many accessories you can actually pack.
  3. Treating extra features as proof of quality. A TSA lock, USB port or 360-degree wheels can be useful, but on their own they say nothing about the strength of the zips, handles or wheels.

The most important specifications when buying travel luggage

1. Dimensions, capacity and weight

For a short flight, a cabin suitcase of around 28 to 40 litres may be sufficient. Always check the external dimensions, including the wheels and handle. A model may appear to meet the cabin baggage limit on paper, but still be refused because of protruding parts.

Also pay attention to the empty weight. A lightweight suitcase leaves more room for clothing within the airline’s weight limit. For example, the ProWorld Explorer has a capacity of 30 litres, dimensions of 34 x 22 x 52 cm and a weight of 2.5 kg. The dimensions are suitable for many cabin layouts, but check your airline’s current requirements before departure.

For longer holidays, a suitcase set with different sizes may be more practical. The KONO set includes a cabin-size case of approximately 40 litres, a medium suitcase of approximately 65 litres and a large model of approximately 100 litres. The suitcases can be nested inside one another, which is useful in a hallway, storage area or cupboard.

2. Materials and protection

A hard-shell suitcase made from ABS has a firm exterior and is easy to clean with a damp cloth. ABS can be damaged by impacts or rough baggage handling, so pay particular attention to the corners, fastening and handle attachment.

A soft bag is more flexible when you want to pack extra clothing. For camping, fishing or trips involving lots of bulky equipment, a 110-litre camping bag is more suitable than a compact trolley. With a foldable travel bag, check the base, wheel attachments and handles. A large capacity is of little value if you cannot move the bag easily.

For everyday use, a water-repellent rucksack is practical in light rain. “Water-repellent” does not automatically mean waterproof. Protect a laptop and important documents with a sleeve or separate waterproof covering.

3. Carrying comfort and freedom of movement

A wheeled travel bag is convenient on flat surfaces such as station concourses and hotel corridors. On stairs and uneven streets, you will often still need to carry it. Four swivel wheels move in several directions and are useful in busy spaces. Two wheels can be easier to use on pavements or uneven floors, but generally require you to tilt the bag while pulling it.

For a laptop rucksack, padded shoulder straps, a supportive back panel and a separate laptop compartment are more important than simply having lots of pockets. If you are looking for a 15.6-inch laptop rucksack, compare the stated laptop dimensions with those of your own laptop. A USB connection is usually a pass-through or connection for your own power bank, so check whether the power bank is included.

Useful checks before you order

Use this short checklist before buying travel luggage:

  • Measure the luggage with the wheels and handle included.
  • Check the permitted dimensions and weight with your airline.
  • Compare the empty weight with the available baggage allowance.
  • Check whether the zips, locks and handles are positioned sensibly.
  • Make sure a laptop compartment is genuinely suitable for your laptop size.
  • Choose a hard-shell suitcase for shape retention or a soft bag for flexibility.
  • For a TSA lock, check the setting instructions and keep your chosen code somewhere safe.
  • Allow a foldable travel bag to dry after use before storing it.

Frequently asked questions about buying travel luggage

What size cabin suitcase can I take on a plane?

This varies by airline and sometimes by ticket type. Check the airline’s current rules on its website. Measure the suitcase’s full exterior, including wheels, handles and any protruding pockets.

How long does a trolley suitcase last?

Its lifespan depends on how it is used, the surface it is pulled over, how heavily it is packed and how well it is maintained. Clean the wheels when sand or dirt gets caught in them, avoid pulling the suitcase over unnecessarily rough surfaces and do not exceed the stated capacity. Products from Koopman International, including certain ProWorld models, are listed as having a minimum statutory guarantee of two years under EU consumer rules.

Is a suitcase set with a TSA lock necessary for every trip?

Not for every trip. A TSA lock is particularly relevant when travelling to countries where airport security may open luggage with an official key. The lock does not prevent luggage from being lost and is no substitute for carefully checking your baggage requirements.
