When it comes to air travel, understanding the rules and regulations regarding the items you can carry with you is crucial. One item that often raises questions is the electronic cigarette. Southwest Airlines, a major player in the aviation industry, has clear guidelines relating to this. This article aims to elucidate the Southwest Airlines electronic cigarette policy and provide travelers with a comprehensive guide.
LIST
What Are Electronic Cigarettes?
Electronic cigarettes, also known as e-cigarettes or vapes, are devices that allow users to inhale nicotine or other substances in a vaporized form. They have gained popularity as an alternative to traditional smoking, particularly for individuals looking to reduce or quit smoking combustible tobacco products.
Southwest Airlines’ Stance on E-Cigarettes
Southwest Airlines permits passengers to bring electronic cigarettes onboard. However, there are stringent rules governing their use and storage during flights. E-cigarettes must be in the hands of the traveler, ensuring they’re not packed in checked luggage. The volatile nature of the batteries used in these devices poses a risk when stored in cargo holds.
Can You Use E-Cigarettes on the Plane? No. Southwest Airlines, in compliance with the U.S. Federal Aviation Administration (FAA) regulations, prohibits the use of e-cigarettes onboard any of its flights. This ensures consistency with the broader smoke-free policy prevalent across all commercial airlines.

Understanding the Safety Measures
While e-cigarettes are allowed in carry-on baggage, it’s important for passengers to understand the safety measures associated with these devices. For instance, the removable batteries should be adequately protected or carried in battery cases to prevent accidental activation or combustion.
- Battery Precautions: Always cover the battery terminals, possibly using masking tape, to ensure no direct contact with metal objects or other batteries, preventing short-circuiting.
- Refill Restrictions: It’s advisable to carry only as much e-liquid as you plan to use throughout your journey, keeping within the 3.4 ounces (or 100 milliliters) limit for liquids in carry-on bags.

Regulations on E-Liquids
E-liquids, used in e-cigarettes, follow the same regulations as other liquids. They need to be placed in a quart-sized clear plastic bag with other carry-on liquids. This rule conveniently aligns with the Transportation Security Administration (TSA) guidelines, making the security check process smoother.
Why Such a Policy?
There are numerous reasons why Southwest Airlines enforces this policy on electronic cigarettes. Ensuring passenger safety is paramount, as is maintaining comfort for all travelers. The potential harm of secondhand vapor and the unpredictable behavior of lithium batteries necessitate strict control measures.
FAQs About Traveling with E-Cigarettes
- Can I charge my e-cigarette on the plane?
- No, charging e-cigarettes or any vaping devices during the flight is prohibited due to fire risks associated with lithium batteries.
- What if my e-cigarette is my nicotine replacement therapy?
- While e-cigarettes are not allowed to be used during the flight, passengers are encouraged to consult their health professionals regarding approved nicotine replacement therapies permissible onboard.
- Is there any chance my e-cigarette could be confiscated?
- If the device or its components are not packed according to airline or TSA regulations, security has the right to confiscate them. Always comply with the given guidelines to avoid inconvenience.
By adhering to these guidelines, passengers can ensure a seamless and safe travel experience, highlighting the importance of staying informed about airline policies. Travelers can enjoy both convenience and peace of mind by respecting the electronic cigarette policies upheld by Southwest Airlines.
