How to get through airport security fast when traveling to O'Fallon
Make your trip to O’Fallon a little bit easier by following these handy security tips:

  • Ensure your boarding pass and passport are easy to reach. You’ll be required to present them straightaway.
  • Wallets, belts and wrist watches should be placed in a tray for X-raying. If you enter the body scanner with these items, you’ll be requested to turn back and remove them.
  • Ensure your phone, laptop and other electronic devices are easy to reach. These items need to be sent through the X-ray machine separately.
