Jeju International Airport (CJU)

Jeju International Airport (CJU) maintains a traveler-friendly policy regarding smoking, offering designated areas both before and after security checkpoints. This ensures that passengers have options regardless of their stage of travel, a welcome feature for many, especially given the airport's high domestic traffic. Before passing through security, passengers can find designated smoking areas located outside the terminal buildings. These outdoor zones are clearly marked and easily accessible for all airport users, including those arriving, departing, or simply waiting for friends and family. It's crucial to only use these specified areas to avoid any penalties or inconveniences, as smoking is strictly prohibited elsewhere within the airport premises. After clearing security, Jeju International Airport provides several options for smokers. According to the most recent updates from August 2025, there is a notable terrace area situated near the food court. This terrace offers an outdoor smoking experience with a pleasant view overlooking the airport tarmac, allowing travelers to relax and smoke while watching aircraft movements. To access this, passengers should head up the escalators to the food court area after check-in and security. For those on international flights, a dedicated smoke lounge is available downstairs, located on the far side after passing through the duty-free zone. While the exact amenities of this lounge were not detailed, it is confirmed as an active smoking facility. Older reports, though potentially subject to change, also indicated a smoking area opposite Gate 2, serving both international and domestic flights, and another smoking room specifically within the international departure area, directly in front of the departure gates. While an update from October 2018 mentioned the closure of a smoking room after security due to refurbishment, the more recent August 2025 information suggests that new or reopened facilities are now available, indicating an improved situation for smokers. For connecting flights, passengers should be aware that they must exit the terminal, re-enter South Korea, use the outdoor smoking facilities, and then re-clear security for their onward journey. Vaping policy is not explicitly stated, so it's advisable to treat it similarly to traditional smoking or inquire locally. Travelers should always look for clear signage and adhere to airport staff instructions regarding smoking locations to ensure a smooth experience.
