There are now two smoking areas in the departure lounge at Antalya airport. They are situated immediately after coming through the final passport control, just before the duty free.
One is to the left, by the side of Popeye's/Burger King, and one to the right by the side of gate 15.
There is stainless steel mesh above the railings and a retractable canopy. Not much seating and no departure board information yet. There are also wall-mounted fans and heaters which have yet to be connected.
