Choosing suitcases and travel bags: how to avoid a disappointing purchase for every trip

Choosing a new suitcase or travel bag seems simple, until you find yourself at the gate with an oversized carry-on suitcase, a wobbly handle or wheels that struggle over cobbled streets. When choosing suitcases and travel bags, there are three common pitfalls to watch out for:

  • Looking only at the capacity in litres: a larger capacity doesn’t automatically mean the bag will fit within the permitted dimensions.
  • Assuming “lightweight” means strong: weight alone tells you nothing about the construction, zips, wheels or handle.
  • Taking airline claims at face value: dimensions and baggage rules vary by airline and can change. Always check your airline’s latest requirements.

The right choice depends on how long you’re travelling, your mode of transport, how you pack and how you’ll carry your luggage. For example, a cabin suitcase for a business trip needs different features from a large bag for camping gear.

Which specifications should you check?

1. Dimensions and baggage allowance

Measure a suitcase including its wheels, handles and any parts that stick out. One airline might accept a 55 × 40 × 20 cm model as cabin baggage, while another may have a smaller limit.

When choosing a lightweight suitcase, consider the balance between size, net weight and capacity. A 20-inch model weighing 2.5 kg with a capacity of 30 litres is practical for short trips, but offers less space than a model with a capacity of around 40 to 46 litres.

Examples from the range:

  • A ProWorld Explorer measures 34 × 22 × 52 cm, has a capacity of 30 litres and weighs 2.5 kg.
  • According to the product specifications, the Beneunder LC363 has a capacity of 46 litres and a net weight of 6.83 lb, approximately 3.1 kg.
  • The KONO Underseat travel backpack measures 40 × 30 × 20 cm and has a capacity of 24 litres. This matches Ryanair’s stated free personal item dimensions, but always check the latest rules before you travel.

2. Materials and construction

A hard-shell suitcase made from ABS, polycarbonate or polypropylene offers a different balance of shape retention, weight and flexibility. ABS is generally lightweight and widely used in affordable luggage. Polycarbonate and polypropylene are also used in models described as shock-resistant or flexible. These are product specifications, not a guarantee of a particular lifespan.

A soft-sided trolley or foldable travel bag may be more convenient if you value a front pocket, flexible compartments or compact storage. When choosing a fabric bag, check:

  • the type of fabric, such as polyester or nylon;
  • the quality of the seams and zips;
  • the protection on the base;
  • whether it has a reinforced frame;
  • how it can be stored when empty.

Water-repellent fabric will generally protect against light rain and splashes. That’s not the same as being fully waterproof. For outdoor luggage, it’s wise to add extra rain protection.

3. Wheels, handles and security

Four 360° spinner wheels make it easy to manoeuvre a suitcase at the airport, as you can move it in several directions. Two wheels are often lighter and work well when pulling a bag directly behind you, but you’ll need to tilt it more on uneven ground.

Also check whether:

  • the telescopic handle locks securely;
  • the wheels spin freely;
  • the zips run smoothly;
  • the interior has compression straps or a zipped pocket;
  • it has a TSA lock if you’re travelling internationally.

A TSA lock doesn’t prevent a suitcase from being opened, but it’s designed to allow authorised security checks without the lock being forced. According to their product descriptions, several KONO and NINETYGO models have a TSA-approved combination lock.

Frequently asked questions about suitcases and travel bags

What size carry-on suitcase can I take on a plane?

It varies by airline, ticket type and sometimes fare class. Check the maximum height, width and depth on your airline’s website. Measure your suitcase, including the wheels and handles.

How long does a suitcase typically last?

Its lifespan depends on how it’s used, how much it carries, the surfaces it’s taken over and how it’s stored. The wheels, zips and telescopic handles tend to take the most wear. Clean the wheels, avoid pulling a trolley over unnecessarily rough ground, and store your bag somewhere dry without overloading it.

Is a luggage set better value than buying suitcases separately?

A luggage set can be practical for families or travellers going on trips of different lengths. Nesting models take up little space. However, only buy a set if you’ll actually use several sizes; otherwise, you may end up paying for and storing luggage you don’t need.
