Outside: Smoking is permitted in marked areas outside the terminal buildings.
Inside: Once you have made it past security, smoking is permitted only in Terminal 1 on the outside terrace which can be accessed from within The Garden Terrace bar/restaurant which is located in “The Loop”. Head towards Food Court 2 to find it, it’s upstairs.
Thanks to Bobby Byrne for recommending this airport.
