Mr Benn, you asked Wiley for a solution. He offered you more than one. There’re few things certain in this world. Death, taxes - and the fact that you're not going to find a solution to this problem without ruffling someone's feathers.
If, as you say, the captain is continually smoking all through a nine hour sector, you've got a potential health problem on your hands. But if you're not game to confront him over this, just suffer in silence, because that's what you're going to have to keep doing if you don't have the balls to front him over this matter.
Are you inferring in your last post that the captain will deny he's smoking on the flight deck if you bring this before management? Give your Manager a bit of credit. He will know the captain’s a heavy smoker. He’ll also know his reputation well enough to know he’s the kind of person to ignore SOPs like the non-smoking rule. Do you think he's so stupid as to think that you, a junior FO, would bring such a complaint to him if the captain wasn't smoking on the flight deck?
If you're not willing to stand up and be counted, do yourself a favour and stop complaining - for you're going to have a lot more experience in the future of many others riding roughshod over you in all areas of your life.
