Remember 3-1-1 for liquids, gels, and aerosols in carry-on luggage:
Three ounces per container
In a clear, one-quart bag
One per passenger.
These bags should be placed in bins going through x-ray like other personal belongings such as keys. This will speed up the process as TSA will not have to search through carry-ons for liquids. For a comprehensive list of exempted liquids and banned items, visit the Transportation Security Administration's (TSA) Web site at www.tsa.gov.
