Can You Bring Aerosol on a Plane? A Comprehensive Guide

Aerosol products are commonly found in everyday items, such as deodorants, hairsprays, and insect repellents. However, when it comes to air travel, there are strict regulations in place to ensure the safety of all passengers and crew members. This often raises the question, “Can you bring aerosol on a plane?” In this article, we will discuss the guidelines and restrictions for carrying aerosol products on a flight, both in checked luggage and carry-on bags.

Understanding Aerosol Restrictions

Aerosols are restricted on planes due to their flammable nature and the potential risk they pose to air travel safety. The Federal Aviation Administration (FAA) and the Transportation Security Administration (TSA) have established specific rules for transporting aerosol products to minimize these risks. These regulations apply to both domestic and international flights and may vary slightly depending on the airline.

Carry-On Luggage

For carry-on luggage, aerosol products are subject to the TSA’s 3-1-1 rule for liquids, gels, and aerosols. This rule states that each passenger is allowed to carry:

  1. Containers with a maximum capacity of 3.4 ounces (100 milliliters) or smaller
  2. All containers must fit into a single, clear, quart-sized plastic bag
  3. One plastic bag per passenger

It is essential to comply with these restrictions, as any aerosol container exceeding the allowed size will be confiscated at the security checkpoint.

Checked Luggage

When it comes to checked luggage, aerosol products are generally allowed, with a few conditions:

  1. Personal care items: Aerosols containing personal care items such as deodorant, hairspray, and shaving cream are allowed in checked baggage as long as they are in containers with a capacity of no more than 18 ounces (500 milliliters) per item. The total net quantity of all such aerosols per passenger must not exceed 68 ounces (2 liters).
  2. Non-flammable, non-toxic aerosols: Aerosols such as cooking sprays, saline solutions, and static removers are permitted in checked luggage, provided they meet the same size and quantity restrictions as personal care aerosols.
  3. Flammable aerosols: Aerosols with flammable contents, such as spray paint, are generally prohibited in both checked and carry-on luggage. However, certain flammable aerosols may be allowed for professional or medical purposes with prior airline approval.

Prohibited Aerosols

Some aerosol products are strictly prohibited on planes, regardless of whether they are in carry-on or checked luggage. These include:

  1. Self-defense sprays: Products like pepper spray and mace are not allowed on planes due to their potential to cause harm.
  2. Explosive aerosols: Aerosols that are classified as explosives or present a significant risk of explosion are not permitted on aircraft.
  3. Other hazardous materials: Aerosols containing hazardous materials that pose risks to health, safety, or the environment are also prohibited.

Tips for Packing Aerosols

When packing aerosols for air travel, it is essential to follow these tips:

  1. Pack aerosols in their original containers, as these containers are specifically designed to prevent leakage and accidental discharge.
  2. Use additional protection, such as plastic bags or bubble wrap, to prevent damage to aerosol containers.
  3. Familiarize yourself with the airline’s specific guidelines for aerosol products, as they may have additional restrictions or requirements.


In summary, you can bring aerosol products on a plane, but you must adhere to the regulations and restrictions set by the FAA, TSA, and individual airlines. By following the guidelines outlined in this article and packing aerosols correctly, you can ensure a smooth
