Before heading to your flight, it is helpful to understand the smoking policy at LAX Airport Smoking Areas. Smoking is permitted only in approved outdoor locations outside the terminals. Indoor smoking and vaping are generally prohibited throughout the airport. Travelers should follow posted signs and use only designated areas to avoid inconvenience. If you leave the secure section of the airport, remember that you may need to complete security screening again before boarding. A little preparation can help make your journey more comfortable and stress free.
