Are you a person who usually packs 20 percent over a bag’s capacity, then sits on the suitcase to get it to close? If so, you might want to opt for a soft case, since they have more “give” than a hard-shell case and are less likely to suffer a split zipper.
Hard cases are usually designed as two clamshell halves that bind together using a zipper in the middle, while soft cases are generally a single chamber that’s opened using a zippered opening on one end.
Hard-Sided or Soft: Hard-sided luggage is typically made of injection-molded plastic in bright colors and finishes, while soft-sided cases by contrast are made of durable fabric with external pockets. Two-wheeled luggage allows greater speed, since you can really make time running across a concourse with it gliding behind you spinner luggage, on the other hand, gives users greater agility, since its four externally-mounted wheels have 360-degree motion and easily stop and start as you weave your way through a crowded commuter gate access area. According to Travelpro, the luggage manufacturer founded by a former pilot who patented a two-wheeled suitcase in the early 1990s and now sells spinner luggage, deciding which type is for you depends on your needs. Four-wheeled suitcases, known as spinner luggage, allow the bag to be pushed alongside you. Four Wheels or Two: Two-wheeled luggage pieces were long the gold standard in rolling luggage, since the two parallel wheels allowed you to pull the case behind you, yet the non-wheeled front corners of the bag let it stand obediently in place where you parked it. And remember, expandable carry-on luggage pieces are great for convenience…until you realize that once you stuff all your shopping purchases in your bag, its dimensions no longer fit within airline parameters.
Exceptions abound, so check with your airline before expecting that your bag will be allowed to board with you. (Though there are exceptions, including Frontier Airlines, which requires bags be under 40 inches combined.) Internationally, a number of major airlines such as Air France, for example, ask that luggage be no more than 21 inches tall, and total less than 45 inches combined (Air France’s combined measurements are 43 inches).
Size: Each domestic carrier makes its own rules about exactly what dimensions they accept for on-board luggage, but generally, domestic carriers require that a bag’s dimensions be no more than 45 inches total-most commonly, 22 inches tall x 14 inches wide x 9 inches deep.
