Yes, you can bring a vape on a private jet, but the rules regarding its usage are determined by the aircraft owner or the charter operator. Legally, the same FAA and international safety rules apply to private jets as they do to commercial ones: vapes and lithium batteries must never be in checked luggage due to fire risks; they must be kept in your carry-on or on your person. While usage is strictly banned on commercial flights, some private jet operators may allow vaping in the cabin if the owner permits it. However, many luxury charter companies still prohibit it to protect the cabin's high-end upholstery and air filtration systems, or to avoid setting off sensitive smoke detectors. If you are chartering a flight, it is standard etiquette to ask the "pilot-in-command" or the broker for permission before using it. If permitted, it is best to use a discreet device with minimal vapor production. Charging vapes is also generally discouraged on board due to the same battery safety concerns that exist on commercial airliners.
