How to get through airport security fast when traveling to Boulder
Make your flight to Boulder a little easier by reading over these clever security tips:

  • Keep your travel ID and boarding pass easily accessible. They’ll be the first things you’ll be instructed to produce by security personnel.
  • You’ll have to place your music on pause for a little while. Earphones and headphones must be taken off and put in a tub to be X-rayed. The same applies to items such as keys and coins.
  • Electronic devices such as tablets, laptops and phones need to be sent through the X-ray machine separately. Make sure they’re easily accessible.
  • When you get to the security checkpoint, you’ll be asked to put all gels, liquids and creams in a separate tub for scanning. Make sure they’re all in containers smaller than 3.4 ounces (100 milliliters) and sealed in a clear zip-lock bag.
  • Loosen your shoelaces before approaching the body scanner. Depending on the style of shoes you’ve got on, security may ask you to take them off.
  • Some countries have stringent quarantine laws. Think about where you’re journeying to and whether or not it’s permissible to fly with fresh fruit and other foods.
