TSA Carry-On Packing Checklist

A well-organized carry-on can make airport screening easier and reduce last-minute repacking. This checklist is based on current United States guidance, but security and airline requirements can change. Always confirm the latest instructions before departure.

Follow the current liquids rule

For standard U.S. screening, the TSA 3-1-1 rule generally limits carry-on liquids, aerosols, gels, creams, and pastes to containers holding 3.4 ounces or 100 milliliters or less. These containers must fit inside one quart-size clear bag, with one bag permitted per passenger.

Medication, infant nourishment, and certain other necessary items may qualify for exceptions. Review the official TSA liquids rule for current requirements and exceptions.

Place the liquids bag where it can be reached easily. Do not bury it beneath clothing or at the bottom of a compression compartment.

Keep batteries in the correct bag

Power banks and spare lithium batteries must generally remain in carry-on baggage rather than checked baggage. Protect battery terminals from short circuits and keep manufacturer capacity markings visible.

If your carry-on is checked at the gate, remove the power bank and spare batteries first. Review the current FAA lithium-battery guidance before departure because additional approval or capacity restrictions can apply.

Organize electronics for access

• Phone and charging cable
• Power bank with its capacity marking visible
• Laptop or tablet when needed
• Headphones
• Compact wall charger
• Camera or watch charger when applicable

Screening procedures can vary by lane and airport, so follow the officer’s instructions. Keep cables together in a dedicated organizer so they do not become tangled with clothing.

Pack medication carefully

Keep essential medication in your carry-on. Leave prescription medication in its original labeled packaging when practical, especially for international travel.

Review TSA instructions for liquid medication and medical equipment. International travelers should also verify whether their medication is restricted at the destination or requires supporting documentation.

Know what belongs in checked baggage

Some everyday objects are restricted from cabin baggage or prohibited entirely. Rules can vary based on an item’s size, type, packaging, and intended use.

Use the official TSA “What Can I Bring?” database to check tools, food, sporting equipment, liquids, sharp objects, and unusual items. Your airline may apply additional restrictions.

Prepare food and reusable bottles

Solid food is generally easier to screen than liquids or spreadable foods. Empty reusable water bottles before entering the checkpoint and refill them after screening.

If you are unsure how a food item will be classified, check the TSA database before packing it. International destinations may also restrict certain foods when you arrive.

Dress and organize for the checkpoint

Keep pockets organized and avoid burying travel documents. Place jackets, loose accessories, and items requested by the screening officer into a bin. Requirements can differ between standard screening, expedited programs, airports, and individual lanes.

The goal is not to remove items before being instructed. The goal is to know where everything is so you can respond quickly to the instructions used at your checkpoint.
