  • Be aware that metal belt buckles can set off the body scanner's alarms. If you have one on, you may be instructed to step back and remove it before moving forward.
  • Ensure your laptop and electronic devices are easily accessible. These items need to be sent through the X-ray machine separately.
  • When it comes to flying with liquids and gels, all passengers are allowed a quart-sized clear resealable bag to transport containers no bigger than 3.4 ounces (100 milliliters).
  • The airport security will likely tell you to take off your shoes before entering the body scanner. Wear a pair that you can take off easily. There's nothing worse than having to do up your laces over and over again.
