Carry On Sizes, Allowances & Policy for Baggage Guide
What is Carry on Baggage?
By definition, a carry-on bag is “small or compact enough to be carried aboard and stowed on an airplane, train, or bus by a passenger”.
Most people who know the word carry on or have used a carry-on typically use them by way of airplane for 2-4 day trips.
A carry-on bag is typically one that you carry onto the plane and store in the overhead bin. All airlines and planes have different requirements and restrictions as to what sizes are allowed, what the maximum weight allowed it as well as what can be carried in the bag.
Domestic airplanes typically provide a larger size to be allowed in comparison to international airplanes (we’ll get more into that later).
Carry On Luggage Airline Regulations
Recently, airlines have become much stricter enforcing their carry-on luggage size requirements.
Previously, airlines measured the size of the actual bag (not including the wheels).
Now, airlines are measuring from the floor to the top of the bag, including the wheels and handle, effectively tightening the restrictions and rendering older carry-ons too large.
Today, most domestic airlines in the United States allow carry-ons up to 22” by 14” by 9,” for a total of 45” linear inches. Many international flights have even tighter restrictions allowing bags sized only 42” linear inches or smaller. These dimensions do not apply to all airlines.
Some airlines have dimensions slightly larger, or slightly smaller, so it is extremely important to check with the airline before using a bag as a carry-on.
Below we have provided a breakdown of most major airlines and their carry-on restrictions.
Although we update this periodically, please be sure to check with the airlines for their most up to date restrictions and fees.
