Luggage & Carry‑ons
Carry‑on rules vary by airline. A 20–22 inch roller fits most international limits, while a 21–22 inch case suits US domestic carriers. Hardshell polycarbonate resists impact with low weight; aluminum looks premium but dents and weighs more. Soft‑sided cases offer external pockets and better expansion.
- Wheels: four spinner wheels glide in narrow aisles; two inline wheels excel on rough sidewalks.
- Handles: seek sturdy telescoping handles with minimal wobble and multiple stop heights.
- Locks: TSA‑approved locks simplify inspections; zippers with puncture‑resistant chains deter prying.
