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

  • Airport security staff will ask to see your travel ID and boarding pass as part of their checks. Store them in an accessible place, so they’re ready for inspection.
  • Belts, wallets and wrist watches are to be placed in a bin for X-raying. If you pass through the body scanner with any one of these items, you’ll be turned back and instructed to remove them.
  • Laptops and other electronic devices must be placed in a tray to be X-rayed.
  • When you get to the security checkpoint, you’ll be asked to place all creams, gels and liquids in a separate tub for inspection. Make sure they’re all stored in containers smaller than 3.4 ounces (100 milliliters) and sealed in a clear zip-lock bag.
  • Untie your shoelaces as you approach the body scanner. Depending on the sort of shoes you’re wearing, security may ask you to take them off.
  • The list of prohibited items is forever changing. Read over your airline’s website to learn about what is not allowed on board their flights.
