Many airlines are now adding e-cigs to their list of prohibited inflight items. This may come as a response to passengers that were not courteous with their vaporizing or because the fake cigarettes may be interpreted as real cigarettes and inspire other passengers to light up. Regardless, it’s now more important than ever to call ahead and ask your airlines policy. You don’t want to be expecting a fix at 35,000 feet only to discover that you’re not allowed to partake. As of February 2010 the following airlines have policies against e cigarettes:

• Continental: “The use of electronic, simulated smoking materials (cigarettes, pipes, cigars) is prohibited on Continental Airlines”
• American: “Devices that are not allowed to be activated at any time are those, including e-cigarettes….”
• Southwest: People report seeing ecigarettes are prohibited in the onboard literature
• Air Canada: “Electronic cigarettes (or ‘e-cigarettes’), provided they remain stowed and unused in your carry-on baggage.”
