Can you vape in an airport?

Whether one can smoke electronic cigarettes at the airport varies and depends on the specific location within the airport.

In general, smoking electronic cigarettes is strictly prohibited in the cabin, but in the terminal building, it needs to be differentiated between the pre-security check area and the post-security check area, with varying regulations.

Here is a detailed explanation of the regulations to help you understand:

✈️ On the plane: Absolutely prohibited (legal red line)
On any commercial flight, smoking electronic cigarettes is strictly prohibited. This is not only the airline's rule but also a legal red line.

Legal aspect: In China, the newly revised "Civil Aviation Law of the People's Republic of China" has clearly included electronic cigarettes in the no-smoking area on board, giving them the highest legal effect.

Consequences of violation: Smoking electronic cigarettes on the plane is an illegal act. The smoke produced by the e-cigarette is highly likely to trigger the smoke alarm on the aircraft, and the lithium batteries in the equipment have the risk of causing a fire in specific environments such as the cargo hold. The violators will face severe penalties, including being taken away for investigation by the airport police, fines, and even being added to the airline's "permanent no-fly" list.

In the terminal building: Dependent on location and airport
The regulations in the terminal building are more complex. The key lies in distinguishing between the "pre-security check" area and the "post-security check" area.

Pre-security check area (Landside): Usually, you can smoke or vape in the designated open-air area outside the terminal building entrance. You need to look for ashtrays or clearly marked smoking spots. Inside the terminal building, most airports prohibit it.

Post-security check area (Airside): This is the most likely to cause trouble, as regulations vary greatly from airport to airport.

Most airports prohibit: Many international airports, such as Gatwick Airport in the UK, Leeds Bradford Airport, and Miami Airport, have no smoking areas in the indoor areas after security check, completely prohibiting vaping.

Some airports have smoking rooms: Some large airports have designated smoking rooms after security check. For example, Berlin Brandenburg Airport (BER) has five smoking rooms near the A, B, and C boarding gates in Terminal 1; Miami Airport (MIA) may also have a smoking area near the D36 boarding gate in the D hall.

 Carrying electronic cigarettes on board: Must follow the rules
Although not allowed on the plane, you can carry electronic cigarettes. The regulations of the Transportation Security Administration (TSA) and most airlines are as follows:

Must be carried with you: Electronic cigarette devices and spare batteries must be placed in carry-on luggage and are strictly prohibited from being checked in. This is to prevent lithium batteries from accidentally starting in the cargo hold and causing a fire.

Prevent accidental start-up: Please ensure the device is turned off and take protective measures (such as removing the atomizer, putting the device in its original packaging or an insulated box) to prevent accidental heating in the luggage.

Carry e-liquid: The e-liquid carried must comply with liquid carry regulations. Generally, a single bottle should not exceed 100 milliliters (3.4 ounces) and must be placed in a transparent 1-liter capacity resealable bag.

Note on prohibited countries: Some countries or regions (such as Vietnam, Myanmar, Singapore, Hong Kong, China) have strict bans on electronic cigarettes, not only prohibiting use but also prohibiting carrying them into the country. Before traveling, be sure to check the laws of the destination to avoid breaking the law.

Summary and practical suggestions
In summary, the regulations for vaping at the airport can be summarized as:

On the plane: At all times, it is absolutely prohibited.

In the terminal building: Before security check, usually only in the designated outdoor area; after security check, depending on the airport, most are prohibited, and some have smoking rooms.

Carry: Devices must be carried with you, and must not be checked in.

For a smooth journey, here are two most practical suggestions:

Advance check: Before departure, be sure to visit the official website of the airport you are going through, search for "Smoking Areas" or "Vaping Policy", and obtain the most accurate information.

Prepare alternatives: Considering that you may not be able to use your e-cigarette for a long time after security check, you can prepare alternatives such as nicotine gum or lozenges in advance to deal with discomfort.
