Most airlines charge for checked baggage. To avoid the fees, many people have started carrying on all of their bags. Because of the increase in carry-on luggage, airlines have begun enforcing their carry-on restrictions more diligently. If your carry-on bag doesn't meet the airline's requirements, you will be required to check it, which will cost you money. Avoid the extra fees by making sure your carry-on meets the requirements for the airline you are flying.
Check the website of the airline you are flying to see what the size restrictions for carry-on luggage are. Restrictions vary, but most airlines require that bags be no more than 22 to 24 inches tall and 14 to 17 inches wide.
Measure your carry-on bag and compare its measurements to the airline's size restrictions.
Check the airline's website to see what counts as a purse or personal item. The airline may restrict the size of a woman's purse. Make sure your purse fits within the size restriction.
Decide what you want your personal item to be. Passengers are allowed one carry-on bag plus a personal item. Personal items include purses, diaper bags and laptops. You may have to combine your purse and your laptop bag to carry everything on.
Weigh your luggage at home. Weight restrictions vary among airlines, so check out what the weight restriction is for your carrier. Make sure your bag weighs in under the weight restriction.
