Regulations on E-Cigarettes During Air Travel
The use of electronic cigarettes, or e-cigarettes, is banned on all commercial flights globally, as enforced by aviation authorities like the FAA and ICAO.
Key reasons for the ban include:

- Fire hazards from lithium-ion batteries overheating in cabin pressure.
- Health concerns over aerosol emissions affecting passengers and crew.
- Compliance with anti-smoking laws under the Clean Air Act and similar regulations.
Carrying e-cigarette devices:
- Must be placed in carry-on luggage only; never in checked bags to prevent battery fires.
- E-liquids must adhere to liquid rules: containers under 100ml in a quart-sized bag.
Penalties for violations:
- Immediate fines and potential flight removal per TSA guidelines.
- Criminal charges in some jurisdictions for endangering safety.
Consult airline policies and destination laws before traveling to ensure compliance.
