how many fluid ounces in an airplane bottle?
But you aren't limited to just one bottle. In fact, according to the TSA… Travelers may carry as many 3.4 ounce bottles of liquid (mini bottles of liquor are 1.7 ounces) that fit comfortably in one, quart sized, clear plastic, zip-top bag. Comfortable means that the bag will seal without busting at the seams.
