Smoking, vaping, and the use of electronic cigarettes are not allowed inside the terminal or beyond the security checkpoint. If you've already cleared security and wish to smoke, you'll need to leave the terminal and complete the screening process again before returning to your gate. Arriving early gives you enough time to use the designated smoking areas and continue your journey without unnecessary delays or added stress.
