When going through airport security, you will need to remove a few items from your bag. These include your liquids, electronics, and anything metal. You will need to take all of your liquids out of your bag and put them in a clear, quart-sized bag. This includes any gels, creams, pastes, and aerosols. You are only allowed to bring one bag per person.    You will also need to take out any electronics larger than a cell phone. These must go through the X-ray machine separately. Be sure to take everything out of your pockets as well. Finally, anything metal will need to be removed from you and placed in a bin. This includes jewellery, belts, shoes with metal accents, and more. Remember to empty your pockets before sending your belongings through the scanner.
