Rules for carry-on luggage vary by airline, but there are common guidelines. Typically, passengers are allowed one carry-on bag and one personal item (e.g., purse, laptop bag). The carry-on should fit in the overhead bin and usually must not exceed 22 x 14 x 9 inches. For personal items, they should fit under the seat in front of you. Always check your airline's specific restrictions before packing, as sizes, weights, and prohibited items may differ. Liquids in carry-ons must be in containers of 3.4 ounces (100 milliliters) or less and placed in a clear, quart-sized bag.
