Gimpo International Airport (GMP)

Gimpo International Airport (GMP), serving the Seoul metropolitan area, maintains a somewhat restrictive but manageable smoking policy for travelers. For those departing or arriving, smoking is strictly prohibited inside the terminal buildings, both before and after security checkpoints, with the exception of designated areas within the International Terminal. Before passing through security, passengers can find designated smoking zones located outside the terminal buildings. These outdoor areas are the only places where smoking is permitted prior to boarding, and travelers should look for clear signage indicating these zones near the main entrances. The policy differs significantly between the Domestic and International Terminals once you've cleared security. In the Domestic Terminal, all smoking areas after security have been permanently closed. This change, implemented to "improve the atmosphere" within the terminal, means that domestic travelers who wish to smoke after security will need to exit the terminal, re-enter South Korea, use an outdoor designated smoking area, and then re-clear security for their connecting or departing flight. This process can be time-consuming and is only feasible if you have ample layover time and the necessary visa/entry requirements. Conversely, the International Terminal at Gimpo does offer facilities for smokers after security. Multiple updates from travelers confirm the presence of a smoking room or lounge airside. One such location is situated near Gate 38, specifically between the Shilla Duty-free store and Gate 38. Another description places a smoking lounge at the very end of the building, on the left side, after Gate 34. These descriptions likely refer to the same general area or very close facilities within the International Terminal's departure concourse. These indoor smoking rooms are enclosed, ventilated spaces designed to contain smoke, allowing international passengers to smoke without needing to leave the secure area. Travelers are advised to plan accordingly, especially if flying domestically or connecting between domestic and international flights. Always look for official signage and follow airport staff directions. While vaping is not explicitly mentioned in the provided content, it is generally treated similarly to traditional smoking in South Korean airports, meaning it would likely be restricted to the same designated smoking areas. Adhering to these rules is crucial to avoid potential fines or penalties, though no specific warnings about fines were detailed in the provided text. The availability of smoking facilities in the International Terminal provides a convenience for international travelers, but domestic passengers should be prepared for a complete absence of post-security smoking options.
