Can you bring a vape on a plane delta?

According to the regulations of Delta Air Lines and the Transportation Security Administration (TSA), electronic cigarettes can be carried on board the aircraft, but only in carry-on luggage and must not be placed in checked luggage.

✈️ Key rule: Carry-on only, no check-in
This regulation is mandatory because the lithium batteries inside electronic cigarettes pose a difficult-to-control risk of catching fire in the cargo hold.

Carrying location: The electronic cigarette device must be placed in carry-on luggage or carried with you. Delta Air Lines' official website clearly states that such devices "can only be brought as carry-on items" (only can be carried as carry-on luggage). The TSA's regulations are also consistent with this, listing it as "Checked Bags: No" (cannot be checked in). If the carry-on luggage is required to be temporarily checked at the boarding gate, the electronic cigarette must be removed and carried into the cabin with you.

Usage restrictions: Only for personal use. Passengers or crew members can carry them, but they must not be used for commercial purposes.

⚠️ Prohibited behavior on board
On the aircraft, there are strict prohibitions for electronic cigarettes:

Prohibited use: On all flights, it is strictly prohibited to use electronic cigarettes or any electronic smoking devices.

Prohibited charging: Similarly, it is strictly prohibited to charge electronic cigarette devices on board, including using a power bank to charge them.

 Important safety advice
To pass through security checks smoothly and ensure safety, please pay attention to the following points:

Prevent accidental activation: TSA requires passengers to take effective measures to prevent the heating elements of the device from accidentally activating. Delta Air Lines also recommends storing the device in a protective case to prevent damage or accidental activation.

Lithium-ion battery limit: The rated energy of the lithium-ion battery inside the device must not exceed 100 Wh (the lithium content of lithium-metal batteries must not exceed 2 grams). If the battery is a detachable spare battery, it can only be carried with you as well.

E-liquid (smoke oil) regulations: If carrying e-liquid, you must comply with the TSA's liquid regulations. Containers with a volume of no more than 100 milliliters (3.4 ounces) can be carried with you and must be placed in a transparent plastic bag with a capacity of 1 quart (approximately 1 liter). E-liquid with a volume exceeding 100 milliliters must be checked in, but the device itself must not be checked in.

Check customs regulations at the destination: Different countries have different restrictions on the import and use of electronic cigarettes. Some countries may completely prohibit them. Delta Air Lines suggests researching the customs laws of the destination before traveling, as the airline is not responsible for items confiscated by local authorities.

In summary, when carrying electronic cigarettes on a Delta Air Lines flight, the key is to remember "carry-on only, no check-in; prohibited use, prohibited charging". Take precautions to prevent accidental activation of the device and follow the relevant regulations on lithium-ion batteries and liquids to pass through security checks smoothly.
