When you buy an aluminium suitcase, look past the shine. What decides whether it lasts is the shell and frame, the wheels and handle, the closure and lock, the interior, the size and the guarantee behind it. This guide walks through each point, so you can recognise a quality suitcase in a shop or online, whatever it is made of.
Start with how you travel
Before comparing models, be honest about your trips. Mostly weekends and business travel with hand luggage only? Then a carry-on is the suitcase you will use most. Longer holidays, or packing for two? Then a check-in size earns its place. Many travellers end up with both: a carry-on for short trips and a larger case for the long ones.
A suitcase is bought for years, not for one journey. Thinking about the next five or ten years of travel usually leads to a better choice than thinking about next month.
The shell and the frame
The material decides much of how well your belongings are protected and how long the suitcase lasts. Aluminium is rigid and strong. It does not crack the way some plastics can, and it keeps its shape under pressure on the belt or in the hold. That is why it protects fragile things well and why it ages slowly.
How to recognise good construction
- The shell feels solid, with no flex when you press the sides.
- The two halves close evenly, without gaps or play along the frame.
- Corners and edges are cleanly finished, with nothing sharp or loose.
- Rivets and hinges sit flush and feel firm when you open and close the case.
One note on character: aluminium dents and scratches over time. That is not a defect but the nature of the material, and many owners come to value it. Every dent tells the story of where you have been.
Weight: a little more, for good reason
Aluminium is slightly heavier than polycarbonate. Check the empty weight, especially for hand luggage, where airlines often allow around 10 to 12 kg in total. Amice suitcases weigh between 4.1 and 5.5 kg depending on the model and size, which leaves sensible room for your things. What you get in return is a shell that protects rather than bends.
Wheels and handle
The wheels are what you notice every day. Look for four spinner wheels that turn a full 360 degrees and roll quietly and steadily on hard floors. Wheels that rattle or wobble in the shop will not improve after a few flights. Replaceable wheels are a real advantage, because wheels take more wear than any other part. The Florence, for example, has wheel sets that can be replaced.
The telescopic handle should extend without play and lock at more than one height, so it suits your stride. Pull it out fully and give it a gentle shake: a well-made handle barely moves.
Closure and lock
Many aluminium suitcases close with a frame closure instead of a zip. There is no zip on the shell that can split or be forced open, and the case shuts with a firm, definite click. Check that the latches close evenly and open smoothly, without effort.
A TSA-approved lock is the standard to look for. Airport security, including in the United States, can open it with a master key without damaging the case. A combination lock that you set with your own code means there is no key to lose. Our lock guide explains how to set it.
Interior and lining
Open the suitcase and look inside. A fully lined interior protects your clothes and covers the construction neatly. Good organisation usually means a strap or buckle on one side and a zipped divider on the other, so both halves stay in place when you open the case on a hotel rack. The stitching of the lining and the quality of the inner zips say a lot about the care taken elsewhere.
Choosing the right size
For hand luggage, most European airlines use limits of around 55 × 40 × 20 to 25 cm, including wheels and handles, but the details differ per airline and per fare. As of 2026, KLM allows 55 × 35 × 25 cm and TUI fly 55 × 40 × 20 cm, while Transavia and Corendon work with 55 × 40 × 25 cm. Always check with your airline before you fly.
- Original Carry-on: 53 × 39.5 × 22 cm, 38 L. Fits the Transavia and Corendon limits.
- Original Carry-on Front Pocket: 53 × 39.5 × 23.5 cm, 40 L, with a front pocket for a laptop and documents.
- Florence Carry-on: 53 × 34 × 20 cm, 38 L. Fits stricter limits such as those of KLM and TUI fly.
- Check-in sizes: the Original Check-in (65 × 48 × 25 cm) and the Florence Check-in (69 × 45 × 27 cm) for longer trips.
The size guide compares each model with the main airline limits.
Guarantee and repair
A guarantee shows how much a maker trusts its own work, so read what it actually covers. Amice gives a lifetime guarantee on the Original collection against material and manufacturing defects, such as faults in closures, locks or construction. Normal wear, scratches and dents are not covered, and neither is damage caused by an airline, which you report to the airline itself. The full terms are on the guarantee page.
Ask as well whether parts such as wheels can be replaced. A suitcase that can be repaired is a suitcase you keep.
Price and value
Aluminium suitcases cost more than most alternatives, and it helps to know why before you compare. Material, hand finishing and a guarantee that runs for life all play a part. Rather than looking at the price on the day, divide it by the years you expect to use the suitcase. We explain this in more detail in why aluminium suitcases cost more.
A short checklist
- A solid shell without flex and a frame that closes evenly.
- Four quiet 360° spinner wheels, ideally replaceable.
- A telescopic handle without play, with more than one height.
- A frame closure and a TSA-approved combination lock.
- A fully lined interior with a strap on one side and a divider on the other.
- A size that matches your airline and the way you travel.
- A clear guarantee that covers defects for the long term.
If you would like to see how these points come together, the full Amice collection is a calm place to start.
FAQ
Is an aluminium suitcase worth buying?
For anyone who travels regularly, usually yes. Aluminium protects well, keeps its shape and ages with character, and with a lifetime guarantee against manufacturing defects you buy once rather than every few years.
Are aluminium suitcases heavy?
They are slightly heavier than polycarbonate. Amice models weigh between 4.1 and 5.5 kg, which leaves enough room within the usual hand luggage allowance of around 10 to 12 kg.
Do dents affect how an aluminium suitcase works?
Small dents and scratches are cosmetic and part of how aluminium ages. They do not affect the closure, lock or wheels. They are not covered by the guarantee, because they belong to the material.
Which aluminium suitcase fits KLM hand luggage?
As of 2026, KLM allows 55 × 35 × 25 cm. The Florence Carry-on, at 53 × 34 × 20 cm, fits that limit. Always check the current rules with the airline before you fly.
Why does a suitcase need a TSA lock?
A TSA-approved lock can be opened by airport security with a master key, so your suitcase can be inspected without the lock being forced. It is especially useful on flights to and from the United States.
