  • Wallets, USB sticks and power banks must be placed in a tub for X-raying. If you walk into the body scanner with any of these items, you'll be asked to turn back and remove them.
  • Ensure your phone, laptop and other electronic devices are easily accessible. These items need to be sent through the X-ray machine separately.
  • When it comes to flying with gels and liquids, each passenger is allowed a quart-sized clear zip-lock bag to transport containers no bigger than 3.4 ounces (100 milliliters).
  • Loosen your shoelaces before approaching the body scanner. Depending on what sort of shoes you've got on, security may instruct you to take them off.
  • Put any multi-tools or other dangerous items inside your checked luggage. Airport security won't permit such things in carry-on baggage.
