My airline allows it and even changed the ops manual 6 months ago. These guys fire up after: every takeoff, turn on the ground, meal, top of decent...

My FO's are kind to me and generally don't smoke with me. If they ask I request them to light up on the ground, window open down wind. I just go into the terminal if there is a Starbucks and let them do everything.

The people are the nice part of the job. The other things can wear you down. Today I can see my shadow, so it's a special day
