By now, everyone knows that liquids need to be kept to a minimum in any carry-on luggage when flying – no more than 3 oz. per item. Also, remember these bottles must be placed together in ONE QUART-sized plastic bag, and the bag must be removed and put through the x-ray machine separately. A few other helpful tips to speed up getting through security and minimizing your chance of a secondary screening by an agent include: avoid wearing a hat or excess jewelry, place your coat in your carry-on bag, wear slip-on shoes, and remember to remove any laptop from its case and place in the screening bin by itself.
