Spirit is a smoke-free airline. Use of tobacco products (including smokeless tobacco) is prohibited on all Spirit flights.
While electronic cigarettes (or e-cigarettes) are marketed as a healthier alternative to smoking and are used to assist users in their efforts to quit smoking, the use of electronic, simulated smoking materials including cigarettes, pipes, and cigars, is prohibited on all Spirit flights. They are only permitted in a passenger's carry-on luggage for all Spirit flights.
