How to get through airport security fast when traveling to O'Fallon
If you like the idea of spending more time at the airport restaurants and less time navigating your way through security on your way to O'Fallon, follow these useful tips:

  • Keep your passport and boarding pass somewhere handy. They'll be the first things you'll be asked for by security personnel.
  • Belts, coins and keys are to be put in a bin for X-raying. If you enter the body scanner with any of these items, you'll be requested to turn back and remove them.
  • All laptops must be taken out of their protective cases and placed in a tub prior to being X-rayed.
  • When you approach the security checkpoint, you'll be asked to put all creams, liquids and gels in a separate tray for scanning. Make sure they're all stored in containers smaller than 3.4 ounces (100 milliliters) and sealed in a clear zip-lock bag.
  • Think about your choice of footwear. Slippers are great because they're super easy to remove when you're at the security checkpoint. Try wearing some on your next journey!
  • Pack any pocketknives or other sharp metal items inside your checked luggage. Security won't allow these on the aircraft.
