This is specifically for Terminal 1 NBO - There is also a smoking room on the ground (apron) level below gate 17 area. There is a lift and escalator to take you down just across from gate 15 or the lift down next to gate 17.

I don’t think the KQ Simba lounge has a smoking area any longer (or they didn’t when I asked last year). Definitely a smoking room in the Pride lounge above gate 17. KQ have opened a new lounge called the Asante lounge, I believe near gate 9/10 and hoping to be able to investigate smoking options there too (will report back).

Not sure if the pay-in lounges at NBO have any dedicated smoking areas.

When I was last in T2 (the very big tent), there were no airside smoking areas.
