  • After that, both you and your carry-on bag will be X-rayed. To speed things up, take off anything that is likely to set the alarm off. Items like your belt, coat and headphones need to go through the machine.
  • All electronic devices, including your phone and tablet, are also required to be separately scanned.
  • Any gels or liquids, such as perfume or toothpaste, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), clear zip-close bag.
  • The right choice of footwear can save you several valuable minutes. Boots and heavy shoes are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Sharp or pointed objects (like knives and scissors) are not allowed in the cabin. They'll be seized at security, so pack them in your checked baggage.
