Liquids and gels that are not allowed in quantities greater than 3.4 ounces in carry-on baggage include face creams and body lotions, toothpastes, and food stuffs such as yogurt, syrup, oils and vinegars. Passengers traveling with smaller quantities of liquid in their carry-on baggage are required to place such items in sealed, see-through plastic bags when passing through security checks.

Other personal items that can travel in carry-on baggage include small aerosols such as deodorants, and scissors, which are allowed if they have rounded tips and a blade length smaller than 4 inches as measured from the fulcrum. Disposable razors can travel in carry-on baggage, as can safety razors without blades, but razor blades must be placed in checked baggage.

Passengers must sheath or wrap sharp objects safely before placing them inside checked baggage, to avoid causing injury to baggage handlers and inspectors. The Transport Security Administration's website contains up-to-date information on prohibited items and the liquids rule under Security Screening in the Travel section.
