2. Domestic vs. International Carry-on: Weight 

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 
Air Canada No limit, as long as you can lift it in the overhead bin 
Air France 26.4 lbs 
Aeromexico 22 lbs for Basic Fare and 33 lbs for Classic, AM Plus and Class Premier passengers 
Air New Zealand 15 lbs for Economy and 22 lbs for Premium Economy and Business Premier passengers 
All Nippon Airways (ANA) 22 lbs 
British Airways 51 lbs 
easyJet 33 lbs 
Iberia Airlines 10 kg for Economy and Premium and 14kg for Business Class passengers

Philippine Airlines 15 lbs 
Ryanair 22 lbs 
Singapore Airlines 7 kg 
Thai Airways 15 lbs 
WestJet No limit, as long as you can lift it in the overhead bin 

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
