The TSA implemented the 3-1-1 rule for liquid items in carry-on bags on August 10, 2006, in an effort to enhance security. Three (3) refers to the clear plastic containers that the TSA limits to a size of 3.4 ounces each. The "ones" (1-1) stand for the one quart-sized, zip-top, clear plastic bag permitted for each passenger who passes through airport security. Any liquids, gels and aerosols need to be packed following the 3-1-1 rule. TSA requires that you remove your clear plastic bag and allow it to be scanned separately at the security checkpoint. TSA does allow medications, baby formula, baby food and breast milk to exceed 3.4 ounces as long as these items are pre-screened and approved by a TSA representative.
TSA regulates the items you can pack in carry-on bags and checked luggage as well as what items are prohibited from air travel altogether. For example, all sharp objects, with the exception of scissors with a blade less than four inches, must go in checked baggage rather than carry-ons. All large sporting goods, such as hockey sticks and golf clubs, receive the same treatment. While you must pack tools such as saws, hammers and crowbars in checked bags, tools, including screwdrivers and wrenches, can go in carry-on bags as long as they are shorter than 7 inches in length. The TSA outlaws all explosives and flammable materials in both checked and carry-on luggage, though common lighters can go in your carry-on bag.
A major concern for some parents and caregivers regards airline safety for unaccompanied minors. Delta Airlines provides a representative look at the major carriers' policies in this regard. You must pay a $100 unaccompanied service fee for all children between the ages of five and 14 who are traveling alone. Delta allows five-to-seven-year-olds to travel only on non-stop or direct flights where there is no need to change planes. Children age eight to 14 can travel on connecting flights, but Delta does not permit them to connect to other airlines, with few exceptions. While 15-to-17-year-olds do not have to use unaccompanied service, Delta will provide it when requested. Rules do vary slightly from airline to airline. For example, United requires unaccompanied service for children between five and 11 years of age, while it is optional for 12-to-17-year-olds.
