Choosing a carry-on can feel harder than it should. There are dozens of sizes, materials, and features, and the wrong bag can mean extra gate fees or a suitcase that just doesn't fit your trip. Knowing a few basics makes it much easier to find a carry-on that works for you.
What Is Carry-On Luggage and Why It Matters
Carry-on luggage is a bag small enough to bring on the plane and store in the overhead bin. Traveling with only a carry-on can save you time at baggage claim, reduce the risk of lost luggage, and help you avoid checked bag fees. Most carry-on suitcases are around 20 to 22 inches tall.
How to Choose the Right Carry-On
1. Check the size limits
Many U.S. airlines allow carry-ons up to about 22 x 14 x 9 inches, including wheels and handles. Limits vary by airline, especially on budget and international flights, so always check before you fly. A 20-inch suitcase like the NINETYGO 20 Inch Carry-On Suitcase is a safe choice for most airlines.
2. Consider the weight
Some airlines also limit carry-on weight. A lightweight bag leaves more room for what you actually need to pack.
3. Look at the wheels
Four spinner wheels roll easily in any direction and are great for smooth airport floors. Two-wheel bags are often sturdier on rough surfaces like sidewalks and cobblestones.
4. Think about organization
Compression straps, zippered dividers, and expandable sections help keep your things neat and give you extra space when you need it.
Common Types of Carry-On Luggage
- Hard-shell carry-ons: Durable and protective, with a sleek look. Great for fragile items. Try the LEVEL8 Airline Approved Carry-On.
- Soft-sided carry-ons: Flexible, often lighter, and usually have handy exterior pockets.
- Carry-on luggage sets: A good value if you also need larger bags for longer trips, like this 20 Inch Carry-On Luggage Set.
Tips and Mistakes to Avoid
- Don't forget that wheels and handles count toward the total size.
- Avoid overpacking an expandable bag, since it may no longer fit in the overhead bin.
- Pack liquids in a clear bag that's easy to reach at security.
- Add a luggage tag so your bag is easy to identify. Browse our Luggage Tags collection for simple options.
