Carry-on bags should be 22 inches long, 14 inches tall and 9 inches wide or smaller. The baggage should be able to fit underneath the passenger seat or in the overhead storage compartment. Many airlines have size-checking devices at the aircraft gate.
The maximum weight of a carry-on bag is 40 pounds.
You may carry one piece of hand baggage plus a briefcase, purse or laptop computer bag. You can also carry a coat, umbrella, cane or another "special" item. Special items include crutches, wheelchairs, strollers, infant car seats or diaper bags, two golf clubs, reading material, cameras or two-wheeled luggage strollers.
You are restricted in the amount of liquid that you can have in your carry-on luggage. You can have the maximum of one 4.3 ounce bottle of liquid, such as cosmetics. This should be packed in a one-quart sized, clear plastic zip-top bag.
