The TSA allows passengers to bring liquids, aerosols, gels, creams, and pastes in their carry-on bags, with the condition that they must be less than 3.4 ounces or 100 milliliters. These items must also fit into a quart-sized bag and follow the 3-1-1 liquids rule. Any non-flammable liquids, gels, or aerosols can be brought in carry-on as long as they follow the 3-1-1 rule. Larger liquid or gel food items are not allowed and should be placed in checked bags. Additionally, carry-on bags must not exceed a certain size limit and should be able to fit into the sizer at the airport. Firearms are not allowed in carry-on bags and must be declared and stored in a locked hard-sided container in checked baggage. The maximum size and weight for carry-on baggage on Hawaiian Airlines is 24 inches tall, 16 inches long, 10 inches wide, and 35 pounds in weight.
