Yes, you can generally fly with an electronic cigarette (e-cigarette) or vape, but there are important regulations you must follow. These rules are primarily for safety reasons and to ensure the comfort of all passengers.
Regulations for Carrying E-cigarettes
- Carry-on Baggage Only: Electronic cigarettes, vaping devices, vape pens, and e-cigars must be transported in your carry-on baggage. They are strictly prohibited in checked baggage. This is because the heating elements and lithium batteries in these devices pose a fire risk if accidentally activated in the cargo hold.
- Spare Batteries: All spare lithium batteries (including those for e-cigarettes) must also be in carry-on baggage and individually protected to prevent short circuits. This can be achieved by keeping them in their original retail packaging, taping over the exposed terminals, or placing each battery in a separate plastic bag or protective pouch.
Usage and Charging Onboard Aircraft
It is strictly prohibited to use or charge electronic cigarettes or any vaping device onboard an aircraft. This rule applies at all times: during boarding, while the aircraft is on the ground, and throughout the flight. Using these devices can trigger aircraft smoke detectors and is considered a serious offense.

Transporting E-liquids
- Carry-on Liquids: E-liquids are subject to standard liquid restrictions for carry-on baggage. Typically, this means each container of liquid must be 100 milliliters (3.4 ounces) or less. All such containers must fit comfortably within a single, transparent, resealable plastic bag of no more than 1-liter (or 1-quart) capacity.
- Checked Baggage: You can pack larger quantities of e-liquids in your checked baggage. Ensure they are well-sealed to prevent leakage due to pressure changes during flight.
Important Reminders
- Airline Variations: While these are general guidelines, specific airlines may have additional or slightly different rules. Always check the policy of the airline you are flying with before you travel.
- Destination Regulations: The legality of possessing and using e-cigarettes and e-liquids varies significantly from country to country. Some countries have strict bans. Research the laws of your destination and any transit countries to avoid legal issues.
Failure to comply with aviation security regulations can lead to confiscation of your device, fines, or denial of boarding.
