Are There Weight Restrictions For Carry On Luggage?
In my search for the answer, I found that carry-on weight limits vary widely by airline, with some enforcing lower limits and others relying on whether passengers can lift and stow the bag themselves. The conclusion I came to is each airline sets the weight limit, and it is according to the size of the plane you will fly. Some airlines say if you can lift a carry on above your head to place it in the overhead compartment, it is not too heavy.
But what happens if your carry on is too big? Not to worry, because if this happens you can gate check it. If it doesn’t fit, it is often gate checked and placed into the cargo hold. You can do this as you step onto the plane and it will be waiting for you when you exit the plane.
If you are flying economy, the weight limit will be lower than a large international flight. To ensure you do not exceed the weight limit, check the airline you will fly for their individual recommendations.
Most of the time, I fly Southwest Airlines, which does not publish a specific carry-on weight limit but requires passengers to stow their bags unassisted. I have never exceeded or even come close to going over that limit. However, if you are packing heavy items like large books, please check the recommendations and weigh your bags in advance.
