What is considered a “liquid” in a carry-on bag?
Water, other drinks, creams, lotions, oils, perfumes, sprays, gels, pressurized containers such as deodorant and shaving foam, toothpaste, mascara and other similar items. To be carried aboard, these items must be 3 oz. or less and carried in 1 clear plastic bag. REI also offer pre-made kits designed for this.
