Taking a few minutes to prepare may help to prevent some real hassles at security or even the frustration of having some personal property confiscated. Most countries now prohibit or strictly limit the size of containers with liquids, gels, aerosols, and pastes that you can take in your carry-on luggage. Empty containers that could contain liquids are usually prohibited as well.

Examples of liquids and gels included in these security measures are:

• Beverages
• Creams
• Hair gel
• Hair spray
• Shampoo
• Suntan lotion
• Toothpaste
• Other items of similar consistency

You ll go smoothly through the security checkpoints in most countries if you follow these guidelines for your carry-on baggage.

• Do not pack or carry any empty containers.
• Limit all liquids, gels, aerosols, and pastes to a maximum container size of 3.4 oz/100ml.
• Place all such items in a quart-size, clear plastic, zip-top bag
• Remove your quart-size bag from your carry-on and place in the provided bin as you approach the checkpoint.

In some airports it is possible to purchase these type of items and take them on board the aircraft once you ve cleared security. However, if your continuing travel takes you through additional checkpoints where they re prohibited, they could be confiscated.

Special provisions are usually made for necessary items such as medications and baby formula. For specific guidelines, visit the additional resources below for links to the appropriate government agency.
