Liquid 3-1-1 Rule
Liquids, gels or aerosols in 3.4-oz. containers or smaller may be carried on airplanes. One passenger may take one quart-sized or smaller clear, plastic bag with liquid containers. Be prepared to place the plastic bag in conveyor belt for screening during check-in.
Prohibited Items
Sharp objects (scissors, razors, knives, swords); sporting goods (bats, ski poles, golf clubs); guns and firearms; martial arts and self-defense items (stun guns, mace, brass knuckles); flammable items (fireworks, common lighters, parts of guns); and tools more than seven inches in length are not allowed.
Required Identification
In addition to providing a boarding pass, all passengers 18 and over must show at check-in a U.S. federal or state-issued photo ID that shows following: name, date of birth, gender and expiration date.
Carry-on Organization
Make sure electronics are accessible and easy to remove. Items such as laptops, DVD players, video cameras with cassettes and full-size video game consoles will have to go through conveyor belt separately. Avoid lengthy delays searching for items that may need to be individually inspected.
Clothing
Wear shoes that are easy to remove. Passengers are required to remove shoes and send them through conveyor belt. Consider wearing slip-on shoes.
Accessories
Avoid metal accessories when possible. While permitted for carry-on, items such as keys, mobile phones, heavy jewelry, metal on clothing or in hair, and heavy belt buckles may set off metal detectors and would need to be removed and sent through the conveyor belt.
