Many airlines allow one free carry-on bag and one personal item. The carry-on bag is subject to size regulations and must be able to fit either in an overhead bin or under the seat in front of the passenger. If a carry-on item does not fit inside the aircraft, many airlines will check it at the gate and transport it to the passenger's final destination. Personal items may include laptops, purses, briefcases, diaper bags or camera bags.
In addition to the free carry-on bag and personal item, there are other items that are small enough to come onto the plane for free. Examples include personal coats or jackets and drinks purchased beyond the security checkpoint.
Liquid items within carry-on luggage are also subject to regulations. As of 2015, the TSA allows passengers to carry on certain liquids in containers of no more than 3.4 ounces, and all containers must fit in one clear, sealed quart-sized plastic bag.Learn more about Geography
