  • 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.
