3-1-1 for carry-ons = 3.4 ounce bottle or less (by volume) ; 1 quart-sized, clear, plastic, zip-top bag; 1 bag per passenger placed in screening bin. One-quart bag per person limits the total liquid volume each traveler can bring. 3.4 oz. container size is a security measure.
Consolidate bottles into one bag and X-ray separately to speed screening.
Be prepared. Each time TSA searches a carry-on it slows down the line. Practicing 3-1-1 will ensure a faster and easier checkpoint experience.
3-1-1 is for short trips. If in doubt, put your liquids in checked luggage.
Declare larger liquids. Medications, baby formula and food, and breast milk are allowed in reasonable quantities exceeding three ounces and are not required to be in the zip-top bag. Declare these items for inspection at the checkpoint.
Come early and be patient. Heavy travel volumes and the enhanced security process may mean longer lines at security checkpoints.

不超过100是指总的,体积是指瓶子的大小不是具体装的多满
香水多小都不能带,肥皂ok
我不建议你带化妆品,同学被收掉过粉饼,口红。.当然化妆品也有出travel size的,很小
.
简单的办法:找一个20X20的密封袋(密保诺之类),用那种travel size(酒店用品之类的大小)的瓶子,然后都扔进去,就好了。你扔的进去的他一般都ok,大多数机场不会那么具体查你到底带了几个小瓶子,但是大瓶子是肯定不行的,一般单个30ml,50ml就行了
