Yes, you can smoke at Guanajuato International Airport (Bajío) (BJX) — open-air smoking outside the terminal building, landside, is permitted; the airport publishes no designated area. VIP Lounge Bajío, the only airside amenity, publishes smoking and vaping as prohibited activities, so no smoking facility after security is confirmed.
BJX sits between León and Silao in Guanajuato and is operated by Grupo Aeroportuario del Pacífico (GAP) — the same group behind the open-air smoking areas inside Guadalajara Airport’s airside VIP lounges.
After Security — VIP Lounge Bajío
VIP Lounge Bajío sits airside in the last-wait area past security, up the escalators opposite Gate 3, open 4:00 am–11:00 pm. Its own published lounge conditions list smoking as a prohibited activity, together with vaping; a connecting passenger who wants a cigarette would need to exit landside and clear screening again.
E-Cigarettes and Vaping
VIP Lounge Bajío’s published conditions rule out vaping alongside smoking; BJX publishes no separate vaping rule beyond that. Mexico’s constitution was amended in January 2025, adding a paragraph to Article 4 that prohibits the production, distribution, sale and transfer of e-cigarettes and vapes nationwide.
