Do I need to check-in my carry-on bag?

Airlines publish the maximum dimensions allowed for carry-on bags. For example, American Airlines states that a carry-on bag's dimensions cannot exceed 22 by 14 by 9 inches, including handles and wheels. The carry-on must also fit into the sizer at the airport; if it doesn't, you'll be required to check it.
