To help us recommend the absolute best luggage to our readers, more than a dozen Condé Nast Traveler editors and contributors spent months (and in some cases, years) road-testing the newest and best-selling bags from top travel brands. These bags accompanied us near and far on planes, trains, buses, and cruises, from local staycations and Hamptons getaways to the Paris Olympics and Marlon Brando’s private island in French Polynesia. We packed these bags to the brim, lifted them into overhead bins, rolled them down cobblestone streets, and inspected every bump and scuff they endured. We considered each bag’s weight, capacity, functionality, price point, and how well it held up after several trips. We also identified smart design features that make a bag stand out from its competitors, like having weight indicators, separate shoe compartments, or ample pockets. After traveling with each bag, we carefully reviewed them, keeping the aforementioned criteria in mind to determine which ones are worth the cost and a spot in our Luggage Week lineup.
