Before arriving at Chicago O’Hare International Airport Smoking Areas, it is helpful to understand the airport's smoking policy. Smoking is prohibited inside all terminal buildings, making outdoor designated smoking areas the only option for travelers. These areas are available before entering the secure section of the airport. If you leave after passing through security, you should allow enough time to return through the screening checkpoint. Checking your airline's boarding time and giving yourself extra time can make the process much easier and help you avoid unnecessary stress.
