How to Choose the Right Suitcase for Carry-On Luggage

Fly Light: Your Ultimate Carry-On Suitcase Guide

If you’re a jet-setting adventurer who likes to keep things simple, you already know the struggle of finding that perfect carry-on suitcase—one that meets airline size rules, holds all your must-haves, and is easy to maneuver. No one wants to wrestle a bulky bag into the overhead bin! As a fellow traveler in my late 20s, I’ve tested countless bags (including some best branded travel bags and a few cool luggage brands), so let me share my hard-earned wisdom with you, my dear travel buddy.


1. Know Your Airline’s Size Rules

Most airlines allow carry-on dimensions of around 55 cm x 40 cm x 20 cm (about 21.5 x 15.5 x 7.5 inches). However, sizes can vary significantly:

  • European Budget Airlines often have stricter rules, sometimes as low as 40 cm x 25 cm x 20 cm (about 15.7 x 9.8 x 7.9 inches).
  • American Carriers generally allow something around 22 x 14 x 9 inches (about 56 x 36 x 23 cm).
  • Certain Asian Airlines might have even more unique limits.

Pro Tip: Always double-check your airline’s website. Some low-cost carriers (like Ryanair or Wizz Air) have smaller allowances, while major airlines like Delta or Emirates may be more generous. The last thing you want is an unexpected fee for your trolley bag at the gate!


2. Hard Shell vs. Soft Shell: Which One to Pick?

Hard Shell Luggage

  • Pros: Better protection for fragile items, water-resistant, and often more stylish for those who love luggage designers.
  • Cons: Less flexibility (you can’t overstuff) and can be heavier; some brands like tumi or other tumi competitors might offer premium hard-shell options at a higher cost.

Soft Shell Luggage

  • Pros: Lighter, can expand a bit more for souvenirs, comes with plenty of pockets.
  • Cons: Less protective for electronics or breakables, and may absorb water in the rain.

If you typically pack electronics or valuables, a hard-shell bag might be your best friend. If you prefer flexibility and want to squeeze in an extra sweater, a soft-shell from one of the durable luggage brands out there could be a winner.


3. Wheels: 2 vs. 4 (or Even 8!)

  • Two-Wheel Suitcases: Great for pulling on uneven surfaces but can be tiring on your arm if your bag is heavy.
  • Four-Wheel (Spinner) Suitcases: Effortless to push and pull in all directions, ideal if you’re weaving through busy airports.
  • Eight-Wheel Suitcases: Basically four-wheel spinners with double wheels, offering extra stability and smooth rolling.

For quick and easy maneuvering in crowded terminals, I personally love a four-wheel spinner suitcase—it just glides!


4. Secure Locks and Safety

We all want to keep our belongings safe. TSA-approved locks are the gold standard in the U.S. because they allow airport security to open and re-lock your bag without breaking anything. This is especially important if you’re traveling with best branded travel bags from trolley bag brands like Samsonite, Delsey (often compared in delsey vs tumi debates), or even luggage similar to Tumi itself.


5. Does Color Matter?

A bright pink or neon green suitcase is a breeze to spot among the sea of black bags. However, a classic black or gray carry-on is timeless and versatile. If you like a pop of personality, go bold! If you want to keep it sleek and professional, pick a neutral color. Either way, a colorful luggage tag can also be a stylish option for easy identification.


6. Brand Loyalty: Is It Worth It?

Some travelers swear by specific trolley bag brands, and many of them do live up to the hype:

  • Rimowa: Known for top-quality, durable hard-shell cases. Pricey, but built to last.
  • Samsonite: Offers a wide range of sizes and styles, reliably made, at moderate price points.
  • Delsey: Popular for being a stylish French brand with both hard and soft shell options, often compared in delsey vs tumi conversations.
  • Travelpro: Many flight crews love them for being lightweight and sturdy.
  • American Tourister: Fun colors, friendly prices, perfect for casual travelers.

If you’re searching for luggage similar to tumi but more budget-friendly, check out tumi competitors like Briggs & Riley or Delsey. Ultimately, the brand name can matter if you’re looking for consistent performance and reliability, but always read reviews. Look for brands for travel bags that invest in quality materials, from zippers to handles.


7. Awesome Luggage Brands on the Market

  • Rimowa – Iconic aluminum cases, high-end looks, and known among the world’s most durable luggage brands.

      So get ready to travel light and conquer the skies with confidence. You’ve got this!

      The lighter you pack, the more memories you’ll bring home.
