The primary difference between the Travelpro Maxlite and Platinum Elite collections is the build quality, features, and price point. The Maxlite (currently Maxlite 5 or Air V2) is designed as the "ultra-lightweight" budget option, using thinner fabrics and basic spinner wheels to keep the weight of a carry-on under 5.4 lbs. It is perfect for casual travelers who want to avoid overweight baggage fees. The Platinum Elite is the "professional-grade" flagship, made from higher-density nylon with genuine leather accents and a much more robust "PowerScope" handle system. It features MagnaTrac self-aligning wheels, which use magnets to keep the wheels tracking straight, and a built-in fold-out suiter for business attire. While the Platinum Elite is nearly 2 lbs heavier and twice as expensive, it comes with a much better "Worry-Free Warranty" that covers airline damage. Essentially, Maxlite is for the budget-conscious traveler looking for lightness, while Platinum Elite is for the frequent flyer who demands durability, organization, and a premium "executive" aesthetic.
