How to get through airport security fast when traveling to Thornton
Make your flight to Thornton a little easier by following these practical security tips:

  • Make sure you know the location of your passport and boarding pass. You don’t want to hold up the queue when you’re asked to hand them over.
  • Coins, belts and keys must be placed in a tray for X-raying. If you enter the body scanner with any of these items, you’ll be instructed to turn back and remove them.
  • Laptops and other electronic devices must be placed in separate trays to be X-rayed.
  • When you approach the security checkpoint, you’ll be asked to put all creams, liquids and gels in a separate tub for inspection. Make sure they’re all in containers no larger than 3.4 ounces (100 milliliters) and sealed in a clear zip-lock bag.
  • Security personnel will likely ask you to remove your shoes prior to entering the body scanner. Pick a pair that you can take off easily. There’s nothing worse than having to do up your laces again and again.
  • Pocketknives and corkscrews are not allowed on board the plane. Stash them away in your checked luggage to avoid leaving them at the security checkpoint.
