Need a carry-on bag for your next trip?

What Is A Domestic Carry-On Bag? 

A domestic carry-on bag is any piece of luggage that can be stowed in the overhead bin of a domestic flight. 

The standard domestic carry-on luggage size is 22″ x 14″ x 9″ (or smaller) for most domestic airlines in the United States. 

From quick escapes to weekend getaways, a domestic carry-on bag is your ideal companion to avoid long waits at baggage claim when traveling within your country’s boundaries. 

What Is An International Carry-On Bag? 

An international carry-on bag is any piece of luggage that is small enough to fit in the overhead bin of an international flight. 

The standard international carry-on luggage size is 21” or below for most international airlines outside of the United States. 

Whether you’re traveling to Italy’s cosmopolitan cities steeped in glitz and glamour or the wild mountainous landscapes of the United Kingdom, an international carry-on bag can help you get your travel essentials from point A to point B. 


What’s The Difference Between Domestic & International Carry-On Luggage? 

So an international carry-on bag typically has to be a tad smaller than a domestic carry-on — but to avoid travel hiccups, it’s best to check the size and baggage weight limits for the specific carrier you’re traveling with. 

We created some handy comparison charts to ensure that packing for your next flight is a breeze!

Most major airlines in the U.S. don’t have weight restrictions for carry-on bags. As long as they fit securely in the overhead bin, you’re good to go.  

But here’s the maximum weight limit for a few American carries that list weight requirements: 

U.S. Domestic Airlines  Weight In lbs 
Frontier Airlines  35 lbs 
Hawaiian Airlines  25 lbs 

Here’s the maximum weight limit for carry-on bags on major international airlines: 

International Airlines   Weight In lbs/kg

You might be wondering, “Why does weight limit matter in an airplane?” 

Well, proper weight distribution plays a key role in an airplane’s overall performance. It affects the plane’s speed, fuel consumption, controllability and structural integrity. 

So, think twice before cheating on your baggage weight! You might need to leave a heavy pair of boots at home, but the good news is you can pack an extra chunky sweater instead — check out our blog on how to pack a suitcase to maximize space and we’ll explain how! 

Rollink tip: No clear carry-on weight limit on the airline’s website? Just make sure that you can lift your carry-on bag over your head with ease! 


3. Domestic vs. International Carry-on: Restrictions 

When it comes to packing your carry-on, restrictions are the same across the board, regardless of whether you’re flying domestically or internationally. 

From alcoholic beverages to sharp objects, it’s essential to know what you can and can’t pack in your carry-on bag to avoid run-in’s with Transportation Security Administration (TSA). 

When packing your carry-on bag, leave these items out: 

  • Alcoholic beverages over 140 proof 
  • Ammunition 
  • Liquids, pastes or gels in containers over 100ml 
  • Self-defense tools such as brass knuckles or pepper spray 
  • Sharp objects such as razor blades or pocket knives 

Rollink tip: Follow the 3-1-1 liquids rule and pack shampoo and other liquids in travel-sized containers. Need to keep your toiletries organized during your trip? Look no further than our water-proof Rollink Hanging Toiletry Bag
