Packing Toiletries? Use the 3-1-1 Rule

Transportation Security Administration

At the screening checkpoint, remove liquids, gels, and aerosols from your luggage and send them through the detector in a separate tray.

Remember the 3-1-1 rule:

  • Three ounces is the maximum size for any liquid, aerosol or gel. 
  • One-quart clear zip-top bag has to hold all your liquids, aerosols and gels. 
  • One zip-top bag per person

Note that the Travel Security Administration allows you to bring more than three ounces of breast milk, baby formula or liquified baby food in your carry-on bag as long as you declare it for inspection at the security checkpoint. Breast milk and baby formula are categorized with liquid medications and you will not be required to taste it in front of a TSA agent.
