How do you pack aerosol cans for flying?

Traveling with aerosol cans—whether for personal care, first aid, or household use—requires understanding both TSA (Transportation Security Administration) and FAA (Federal Aviation Administration) guidelines. Aerosol cans contain compressed gases, making them potentially hazardous if not packed correctly. Mishandling can lead to leaks, explosions, or confiscation at security checkpoints. This article breaks down the rules, offers practical packing strategies, and compares different aerosol can products to ensure a smooth travel experience.

Understanding the TSA 3-1-1 Rule for Aerosol Cans

The TSA 3-1-1 rule governs liquids, gels, and aerosol cans in carry-on luggage. The rule states:

• 3.4 ounces (100 milliliters) is the maximum allowed per item.

• All aerosol cans and liquids must fit into a single, quart-sized, clear, resealable bag.

• Only one bag per passenger is allowed.

Aerosol cans exceeding 3.4 oz cannot be carried on and must be packed in checked baggage, if permitted. However, even in checked luggage, restrictions apply.

What Types of Aerosol Cans Are Allowed?

The TSA website (https://www.tsa.gov/travel/security-screening/liquids-aerosols-gels-rule) specifies that the following aerosol cans are generally permitted in carry-on and checked baggage, provided they meet size and quantity limits:

• Personal care aerosols (e.g., hairspray, deodorant)

• First aid sprays (e.g., antiseptic sprays, sunscreen)

• Medicinal aerosols (e.g., asthma inhalers, allergy sprays)

However, certain aerosol cans are prohibited entirely, such as:

• Flammable aerosols (e.g., spray paint, cleaning agents)

• Self-defense sprays (e.g., pepper spray)

Packing Aerosol Cans in Carry-On Luggage

If you need to bring aerosol cans in your carry-on, follow these steps:

1. Check Size and Quantity Limits

• Only aerosol cans ≤ 3.4 oz (100ml) are allowed in carry-on.

• Place them in a clear, resealable quart-sized bag.

• Do not exceed one bag per person.

2. Secure the Aerosol Can

• Ensure the nozzle is fully closed to prevent accidental discharge.

• Consider using a protective cap (available from brands like Hengyu Can) to avoid leaks.

3. Place in the Designated Bag

• Keep the aerosol cans upright in the bag to prevent tipping.

• Place the bag in an easily accessible pocket for TSA screening.

4. Declare if Necessary

• If you have medicinal aerosol cans, inform the TSA officer during screening.

Packing Aerosol Cans in Checked Baggage

While aerosol cans are more flexible in checked luggage, they still face restrictions.

1. Size and Weight Limits

• Aerosol cans up to 18 oz (500ml) are generally allowed in checked baggage.

• The FAA restricts the total weight of all aerosol cans to 2 kg (70 oz) per person.

2. Safe Packing Practices

• Place aerosol cans upright in a protective sleeve or case.

• Wrap in plastic wrap or a sealed bag to contain potential leaks.

• Avoid overpacking to prevent pressure buildup.

3. Prohibited Aerosol Cans in Checked Luggage

• Flammable aerosols (e.g., hair spray with high alcohol content)

• Aerosol insecticides (unless specifically permitted for travel)

Frequently Asked Questions (FAQ)

F: What are the FAA rules for aerosol cans?

Q: The FAA limits the total amount of restricted medicinal and toiletry articles, including aerosol cans, in checked baggage. The total aggregate quantity per person cannot exceed 2 kg (70 ounces) or 2 L (68 fluid ounces). The capacity of each container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).

F: How many 3 oz bottles can I take on a plane?

Q: You can bring as many 3-ounce (or 100ml) bottles as you can fit into a single, quart-sized, clear, resealable bag. This typically allows for about 6 to 9 small bottles, depending on their size and how they are packed. Remember that the bag needs to be clear and resealable for TSA screening.

F: Can I bring hairspray on a plane?

Q: Yes, but only if it’s ≤ 3.4 oz (100ml) in carry-on. Larger sizes must go in checked baggage, provided they are ≤ 18 oz (500ml).

F: Are sunscreen sprays allowed on planes?

Q: Yes, sunscreen sprays are permitted in both carry-on (≤ 3.4 oz) and checked baggage (≤ 18 oz). However, they must be in their original packaging.
