Aluminum luggage is more durable than polycarbonate or soft-sided luggage, though it's still prone to scratches and dents. It's also more secure, as aluminum suitcases typically close via latches rather than zippers.

Whether an aluminum suitcase is "worth it" depends on your priority between aesthetic longevity and weight efficiency. Aluminum luggage, pioneered by brands like Rimowa and Zero Halliburton, is prized for its high-fidelity durability and security. Unlike polycarbonate or ABS plastic, aluminum does not crack under the extreme pressure of baggage handling systems; instead, it develops "character" through small dents and scratches over time, which many frequent travelers find appealing. It offers superior protection for fragile items and is nearly impossible to slice open, providing a higher level of theft deterrence. However, the primary drawback is weight. A standard aluminum carry-on can weigh 10 to 12 lbs (4.5 to 5.5 kg) empty, which can consume nearly half of the weight allowance on international or low-cost carriers in 2026. Furthermore, they are significantly more expensive, often costing three to four times more than high-quality hardshell plastic alternatives. If you are a business traveler seeking a "lifetime" bag that makes a professional statement and you don't mind the weight penalty, aluminum is a premier investment; otherwise, modern high-grade polycarbonate is often more practical for the average vacationer.
